Improved Performance of Direct Torque Control of Induction Motors
Miss. Neha P. Nemade, Prof. Suraj R.Karpe
DOI: 10.17148/IJIREEICE.2015.3501
Abstract: This paper presents an improved Direct Torque Control (DTC) of induction motor. DTC drive gives the high torque ripple. In DTC induction motor drive there are torque and flux ripples because none of the VSI states is able to generate the exact voltage value required to make zero both the torque electromagnetic error and the stator flux error. To overcome this problem a torque hysteresis band with variable amplitude is proposed based on fuzzy logic. The fuzzy logic controller is used to reducing the torque and flux ripples and it improve performance DTC especially at low speed.

A prototype for secret based data Encryption Scheme for Smart Grid Wireless Communication
Gadi Anvesh
DOI: 10.17148/IJIREEICE.2015.3502
Abstract: Integrating information network into power system is the key for realizing the vision of smart grid, but also introduces many security problems. Moreover, smart grid is an attractive target for various hackers with diversified motivations, e.g. unethical customers may want to modify their meter readings to evade the electric charge; malicious users are able to extract the behaviors of household by eavesdropping the communications of smart meters. Wireless communication offers the benefits of low cost, rapid deployment, shared communication medium and mobility at the same time, it causes many security and privacy challenges. In this paper, the concept of dynamic secret is applied to design an encryption scheme for smart grid wireless communication. Dynamic wireless encryption works in a different concept where the master key is changed during time. Master key, the key which is needed to communicate between sender and receiver. Even if a hacker captures the key, he will not be able to receive data continuously from sender since the master key will change with time. In our project, a smart grid platform is built, employing the ZigBee protocol for wireless communication. Thus a data encryption standard (DES) algorithm has been developed to transmit our data securely. The length of the key that is generated in data encryption standard (DES) is 64 bits out of which 8 bits are removed for parity so now the key is of length 56 bits .So there are 72 quadrillion number of keys that can be generated. A dynamic secret-based encryption demo system is designed based on this platform. The results show that it is impossible for the adversary to track the updating of the dynamic encryption key.

DOI: 10.17148/IJIREEICE.2015.3504
Abstract: Data publishing is recently focused more for the data analysis. In recent days, the data creation is enormous in all the fields. Predictive analytics uses all the data collected from various sources for predicting the future even though there is uncertainty in information gathered. The data used for analysis should not affect the privacy for the record owners. In all the sectors, organizations use their data for predictive analytics. The organizations should not reveal the sensitive details of the record owners for any cause. In general the data privacy is preserved with data anonymization. There are algorithms such as k-anonymity, l-diversity and t-closeness for data anonymization. On anonymizing the data, there are threats that can disclose the information about the record owner. In this paper we discussed about the threats that affects the privacy of record owners in data publishing.

DOI: 10.17148/IJIREEICE.2015.3505
Abstract: Wind Power is one of the fast growing renewable energy source in India and the world. India, in particular, is among top five countries in wind power generation with present Installed capacity of over 18000 MW and more. As demand grows, generation capacity in modern wind turbine goes in Megawatt scale. A modern big turbine requires sensing and controlling of various parameters like temperatures of moving parts. Fibre Optics with its electrical isolation and being light weight characteristics can have great potential to sense control parameters of wind turbine and to communicate to the control unit. Fibre optic sensors are precise and reliable under electrical hazardous environment of wind energy. Fibre Optic Technology has proved itself in present generation Communication system. The same high speed long, distance communication Networking can apply in onshore and offshore wind farm. The lower attenuation, greater bandwidth compared to copper cables and above all, immunity to high electric power, fibre optics are proving its significant role in automation of wind turbines. The signals that carry optical fibre provide reliable information for health monitoring and controls of wind turbines.

Neutral Point Voltage Balancing in Three Level Neutral Point Clamped (NPC) Multilevel Inverter Using Carrier Based Offset Addition PWM
Uthaya Suresh Balu E
DOI: 10.17148/IJIREEICE.2015.3511
Abstract: Three-level Neutral Point Clamped (NPC) converters are widely applied in high power medium voltage electrical drive systems. A significant problem related to the three-level NPC converters is the fluctuation of the neutral-point voltage. In this paper, a neutral point voltage balancing technique is proposed that injects an offset voltage into the sinusoidal modulating signals of the conventional Carrier-Based Pulse Width Modulation (CBPWM) method. Furthermore, when the injected offset voltage is maximized, it is not only balance the dc-link capacitors voltages, but also reduce output voltage distortions and switching losses. And also, the CBPWM offset addition method has reduced the switching commutations number to the lesser values. The performances of the strategies were verified by simulation tests. Modulation (PWM) strategies developed with continuous offset addition is demonstrated by MATLAB/SIMULINK based simulation presented in this paper.

A Survey on Novel method of Efficient Boost Rectifier using Fuzzy Logic Controller
Hemalatha B.N, Jagadheesh Kanade
DOI: 10.17148/IJIREEICE.2015.3515
Abstract: A single stage ac-dc power electronic converter is proposed to efficiently manage the energy harvested from electromagnetic generators. The conventional ac-dc converters for energy harvesting system with diode rectifiers suffers considerable voltage drop results increase in power loss of circuitry and complexity. The proposed topology combines a boost converter and buck boost converter to condition the positive and negative half portions of the input ac voltage, respectively. The proposed converter avoids the use of bridge rectifier and converts the ac input to the required dc output. By using Fuzzy compensator we can increase the dc output voltage compare to PI compensator system. The simulation is done with the help of MATLAB using simulink.

Design of Internal Model Controller for an Open Loop Unstable CSTR Process
S. V. Prasanna Kumar, Ritesh Singh, S. Nagammai
DOI: 10.17148/IJIREEICE.2015.3516
Abstract: A CSTR is an Continuously Stirred Tank Reactor with the main function of agitation and to achieve constant composition. It has an important role in chemical process plants. A CSTR has an higher degree of nonlinearity when compared with other chemical reactors, this is mainly due to the temperature variations that occur because of uncertainity in feed. Hence, temperature control is a strenuous task. The proposed work focusses on control of temperature in a jacketed chemical reactor, by effectively designing a internal model controller (IMC). The process is a open loop unstable system due to the effect of scale-up on the steady state and other dynamic characteristics. The proposed digital controller is capable of providing system stability, set point tracking and disturbance rejection. The simulation result shows the suitability of using the proposed controllers for control of the unstable CSTR process.

Energy Efficiency Improvement of DWEHC Protocol Using Fuzzy Logic
Komal Bhoite, Pramodkumar Kulkarni
DOI: 10.17148/IJIREEICE.2015.3517
Abstract: The WSN is a specialized wireless network made up of a large number of sensors and at least one base station. The foremost difference between the WSN and the traditional wireless networks is that sensors are extremely sensitive to energy consumption. Energy saving is the crucial issue in designing the wireless sensor networks. Since the radio transmission and reception consumes a lot of energy, one of the important issues in wireless sensor network is the inherent limited battery power within network sense in order to maximize the lifetime of sensor nodes; it is preferable to distribute the energy dissipated throughout the wireless sensor network. In this paper we are aiming to present new energy efficient routing protocol for WSNs. We are going to propose a Extended Distributed Weight-based Energy- efficient Hierarchical Clustering protocol (EDWEHC). Each node first locates its neighbours (in its enclosure region), then calculates its weight which is based on its residual energy and distance to its neighbours. The largest weight node in a neighbourhood may become a clusterhead. Neighbouring nodes will then join the clusterhead hierarchy. The clustering process terminates in O(1) iterations, and does not depend on network topology or size. To improve the energy consumption performance fuzzy logic rules are integrated in DWEHC.

A Compact Two Element UWB MIMO Antenna
Vikash Kumar, Ankit Pawaria
DOI: 10.17148/IJIREEICE.2015.3518
Abstract: In this Paper we design two- element MIMO antennas and various isolation structures and mechanisms to reduce the mutual coupling between the two elements, out of which two major antenna designs are proposed and analyzed separately for their isolation, bandwidth and radiation characteristics. The MIMO antenna system consists of two semicircular radiating elements on a single low-cost FR4 substrate of a compact size of 35 mm × 40 mm and is fed by a 50-Ω microstrip line. A T- shaped slot is etched on the radiating elements to enhance the impedance bandwidth. The proposed antenna system operates over a wide frequency range from 4.4 to 10.7 GHz. A fork-shaped structure is introduced in the ground plane to increase the isolation between the antennas. Simulated results of S-parameters of the proposed antenna system are obtained and a high isolation of -20 dB is achieved in most of the band, which is found suitable for MIMO applications.

Maximization of Throughput in Cognitive Radio using non-persistent CSMA combined with Reinforcement Learning
Nisha Kiran, Ravi Raj, Alisha Khan
DOI: 10.17148/IJIREEICE.2015.3523
Abstract: The Cognitive Radio project aims to develop radios that can sense the existing spectrum and identify and use free frequency bands. Primary users using time division multiple access (TDMA) are licensed users who are assigned with certain channels, and secondary users using carrier sense multiple access (CSMA) are unlicensed users who are allowed to use the channels assigned to a primary user when it is free. This paper introduces a novel spectrum sharing protocol for secondary users combining multichannel non-persistent carrier sense multiple accesses (CSMA) and reinforcement learning.

Pramod Sharma, Neelam Saraswat
DOI: 10.17148/IJIREEICE.2015.3524
Abstract: The objective of this paper is to present recent developments in the field of Induction motor fault signature analysis with particular regard to Sound signature analysis of induction motor of fan. The different types of fan faults that can be identified from the sound signature analysis [1] are, for example, rotor faults, bearing faults, unbalances wings etc. Corresponding to the above-mentioned faults, many types of machine fault signature analysis techniques [2] have been proposed for motor faults detection and diagnosis. These techniques include vibration monitoring, motor current signature analysis (MCSA) [3–6], electromagnetic field monitoring [7], chemical analysis, temperature measurability [8, 9], infrared measurement, acoustic noise analysis [10], and partial discharge measurement [11, 12]. Among these methods, vibration analysis, current analysis and Sound signature analysis are the most popular due to their easy measurability, high accuracy, and reliability.

Mrs. V. V. Joshi, Gaurav Kumbharde, Jagrup Prasad
DOI: 10.17148/IJIREEICE.2015.3525
Abstract: Cognitive radio network (CRN) is an intelligent system that gives solution to underutilization of spectrum by detection of spectrum holes. For this purpose, important tasks including spectrum sensing, spectrum analysis and spectrum decision are required to be performed. Spectrum sensing is the crucial step as it provides fast and reliable detection of primary users (PU) and helps in evasion of disturbance to their transmission. Different methods of enhancements in local sensing scheme have been proposed in the literature. However, cooperative spectrum sensing schemes are preferred as they provide significant gains in CRN performance by countering shading effects. The consensus-based distributed cooperative spectrum sensing (CDCSS) scheme depends on energy detection for local sensing.

Microcontroller Based Automatic Waste Segregator
M.K.Pushpa, Aayushi Gupta, Shariq Mohammed Shaikh, Stuti Jha, Suchitra V
DOI: 10.17148/IJIREEICE.2015.3529
Abstract: The rising population of India poses serious threats with regard to the availability of living space, utilization of natural resources and raw materials, education and employment. But another serious peril that follows is the escalating amount of waste generated each minute by an individual. An astounding 0.1 million tonnes of waste is generated each day in India. Sadly, only 5% of this colossal amount of waste is recycled.One possible solution for this problem could be segregating the waste at the disposal level itself. In India, the collection, transportation and disposal of MSW are unscientific and chaotic. Uncontrolled dumping of waste on outskirts of towns and cities has created overflowing landfills which are not only impossible to reclaim because of the haphazard manner of dumping but also has serious environmental implication in terms of ground water pollution and contribution to Global warming [1].This has found to reduce the average life span of the manual segregators. Developing a mechanized system to help save the lives of many and making the world a cleaner and a greener place is the noble objective of our project.We have thus proposed an automatic waste segregator that aims at segregating the waste at the disposal level itself. It is designed to sort the waste into 3 major categories, namely metallic, wet and dry, thereby making waste management more effective. To set the ball rolling, we have proposed this project to give back to our nation, making our India a „Swachh Bharath‟.

Improved TMSE with imperfect CSI in MU-MIMO
Pappu Sri Santosh, A.Ch.Sudhir
DOI: 10.17148/IJIREEICE.2015.3530
Abstract: Although tremendous progress has been made in the past years on MU-MIMO systems, there still exist a number of problems. We believe that the most important one is related to the channel state information (CSI). In wireless communications “Evaluation of Imperfect CSI Criterion in Multi User MIMO Transceiver System” is still area of concern. Multiple transmit and receive antennas can be used to form multiple-input multiple-output (MIMO) channels to increase the capacity by a factor of the minimum number of transmit and receive antennas. In this paper, we propose a novel joint linear transceiver design for single-user multiple-input, multiple-output (SU-MIMO) systems and Multi-user multiple-input, multiple-output (MU-MIMO) systems employing improper signal constellations. A novel contribution in this paper is to derive a closed-form optimum linear pre coder and decoder for both the downlink and uplink MU-MIMO systems with improper modulation by solving the non convex optimization problem under total power constraint. The simulation results show that the performance of the proposed design is improved over the previous design.

Chandrakala M D and Dr. Suraiya Tarannum
DOI: 10.17148/IJIREEICE.2015.3532
Abstract: Non-Subsampled Contourlet Transform (NSCT) is a improvement of Contourlet Transform (CT). The important properties of the Non-Subsampled Contourlet Transforms are shift-invariance, high resolution, and high directionality. Non-Subsampled Transform represents high directional information and captures geometrical structures of the objects. In the proposed method the given numbers of decomposition levels are applied to multispectral Image and the Panchromatic Image in the relative ratio. Fine levels and coarse levels are obtained. During the Simulation process Bilinear Interpolation method is applied for fine levels of the Panchromatic Image and Multispectral Image. The coarse level of multispectral Image given to a local edge preserving filter, and later inverse NSCT is applied to get the Pan-Sharpened Image. Non-Subsampled Contourlet Transform preserves spectral and spatial information. The computation time is decreased. Considerably the detailed information can be preserved by applying Up sampling after NSCT. By this Upsampling after NSCT, the coefficients are fused by the application of Fusion Rule. After Inverse NSCT, the obtained Image is a Pan Sharpened Image. An additional Local Edge Preserving Filter (LEP) is used before NSCT to get Pan Sharpened Image with high Spatial and Spectral qualities. By Images and quality indices values, we can observe the improved Spatial and Spectral qualities.

Sylish S V, Anju V
DOI: 10.17148/IJIREEICE.2015.3533
Abstract: The number of diabetic patients are increasing nowadays. So the chance for diabetic retinopathic (DR) diseases are also increasing. From the different diabetic retinopathic diseases, microaneurysms (MAs) are the first detectable symptom of DR. This paper makes an attempt to MA detection using blood vessel segmentation and profile analysis. After the removal of connected blood vessels, the remaining regions are used for the exact detection of microaneurysms. Ramp analysis and peak detection step is performed on the profile of the maximum intensity regions and a set of values indicating the size, height and shape of the peaks are calculated. Detected candidates are classified using feature set and naive Bayes classifier. Score values are assigned to each detected microaneurysm regions. The results show that proposed method significantly reduces the number of false positives per image and the performance is evaluated using Free-response Receiver operating characteristics(FROC)curve and calculated sensitivity and specificity which is competitive to the existing methods.

DOI: 10.17148/IJIREEICE.2015.3536
Abstract: Wind energy is gaining interest now-a-days as one of the most important renewable sources of energy due to its eco-friendly nature. But the major disadvantage lies in variable speed wind generation and this paper gives a study on control of Wind driven doubly fed Induction Generators. The speeds above and below Synchronous speeds are obtained using a bidirectional power flow converter. By using this reactive power is controlled and hence the overall Power factor of system can be kept at unity under varying load conditions. . This paper presents a novel method for power quality improvement of Wind Energy Conversion System (WECS) by compensation of grid harmonic currents produced by non-linear loads. The proposed method which has been applied to a Doubly Fed Induction Generator (DFIG) through rotor side converter(RSC), provides simultaneous speed control and power quality improvement. The Direct Power Control (DPC) method with constant switching frequency has been used for RSC control and power quality improvement has been performed by compensation of harmonic's active and reactive power of nonlinear load. This paper presents simulation results of a Grid-connected DFIG.

Application of Distribution Static Synchronous Compensator in Electrical Distribution System
Smriti Dey
DOI: 10.17148/IJIREEICE.2015.3537
Abstract: The concept of flexible alternating current transmission systems devices (FACTs) and custom power devices (CPD) are widely used for improving the flow of power in a transmission and distribution network. The term Power quality and Reliability are becoming very important issues for the sensitive loads connected to the systems. For low voltage distribution system Custom Power Devices (CPDs) such as Dynamic Voltage Restorer (DVR), Distribution static synchronous compensator (D-STATCOM) and Unified Power Quality Compensator (UPQC) etc. are used for improving the quality of power and reliability of supply without affecting entities such as factories, industries, and home etc. Among the Custom Power Devices D-STATCOM is mainly used to mitigate the fluctuation in voltage due to fault and the application of dynamic load which is connected in shunt with the main line that injects or absorbs the reactive current into/ from the line to maintain the flat load voltage profile. In this paper the simulation of D- STATCOM is done by using SIMULINK tool of MATLAB software. The control signal of the D-STATCOM is provided through the discrete PWM generator and PI Controller to improve the quality of power under different abnormal conditions like single line to ground fault (LG) double line to ground fault (LLG), three phase ground fault and the application of Dynamic Load has been described in this paper and the simulation result shows the efficient performance of D-STATCOM under different voltage swell and sag conditions.

Artificial Neural Network Controlled DSTATCOM for Power Quality Improvement
S. Sherin Jasper
DOI: 10.17148/IJIREEICE.2015.3538
Abstract: The paper intends to develop the artificial neural network control algorithm for the control of DSTATCOM for the improvement of power quality. The presence of nonlinear loads makes the voltage to be deviated and current to be distorted from its sinusoidal waveform quality. Thus harmonics elimination, load balancing and voltage regulation is the heavy task that has to be accomplished to maintain the quality of the power. The performance of any device depends on the control algorithm used for the reference current estimation and gating pulse generation scheme. Thus the artificial neural network based Back Propagation (BP) algorithm has been proposed to generate the triggering pulses for the three phase H bridge inverter (DSTATCOM).The fundamental weighted value of active and reactive power components of load currents which are required for the estimation of reference source current is calculated by using BP-based control algorithm. Based on the difference of the target voltage and the generated voltage, the triggering pulse for the inverter is obtained by the BP algorithm. Then the voltage is injected at the point of common coupling to compensate the reactive power. Thus by regulating the voltage and compensation of reactive power, the power quality can be improved. The simulation modelling of the Back propagation algorithm controlled DSTATCOM and the PWM controlled DSTATCOM and the comparative analysis of the algorithms is presented in this paper.

DOI: 10.17148/IJIREEICE.2015.3539
Abstract: Viterbi Decoder employed in digital wireless communication plays a dominant role in overall power consumption of trellis coded modulation (TCM) decoder. Using T-algorithm dramatically reduces the decoding speed .The key point in improving clock speed of T-algorithm is to quickly find the optimal Path Metric (PMoptimal). The proposed Viterbi Decoder (VD) implementation can reduce the power consumption with less reduction in the maximum decoding speed. The trellis path in the circuit is found using trellis coded modulation. Pre-computation technique has been adopted for the trellis coded modulation. This paper focuses on the realization of convolutional encoder and Viterbi decoder with a constraint length (K) of 7 and code rate (k/n) of 3/4 using Field Programmable gate array (FPGA) Technology. The convolutional encoder and Viterbi decoder (VD) using T-algorithm has been coded in Verilog HDL code and implemented in Xilinx ISE 14.2

Abstract: Most of the process systems exhibits non-linear behaviour, so conventional controllers are not able to provide accurate data. At present, various soft computing techniques are used to overcome imprecision and uncertainty effects of conventional controllers. Various soft computing techniques like fuzzy logic, genetic algorithm and particle swarm optimization have been suggested for optimum setting of PID controller parameters. In this paper, the performance of all the three soft computing techniques is compared for three tank level process control system. This comparative study is carried out for set point tracking of three tank level process using MATLAB/ SIMULINK. The simulation results shows that tuning the PID controller using PSO provides fast and stable system with low overshoot.

DOI: 10.17148/IJIREEICE.2015.3543
Abstract: Wind Energy constitutes 4% of the total electricity produced in the world and is a very significant source of renewable energy. Power generation by wind turbine generators, or WTGs, is a proven green energy technology in both land and offshore environments. However, wind farms located either onshore or offshore are often in remote and not easily accessible locations. Additionally, their height above ground can pose unique maintenance, repair and lightning strike challenges that must be addressed to make wind power renewable energy reliable and economical. The right data and communication cables are very important in wind farms as the farms are usually quite large in area and very often, the environment is quite harsh in such locations. Hence it is necessary to use power transmission cables that are resistant to such conditions, and able to transmit power over long distances with the required efficiency. The two main options that are chosen for transmission cables include Bus-Ethernet and Fibre Optic Cables. Owing to several important reasons, the use of Fibre Optic Cables is highly preferred as compared to the former. Fiber optics (FO) technology is probably best known for use in high-speed, high-bandwidth telecommunication applications. But today fiber optics data and control links have replaced copper links in wind turbines and farms making them a critical part of a wind farm operator’s solutions for minimizing costly downtime and service interruption. Optical fibre network provides real-time data capture to monitor wind turbine uptime, performance and power output – even from remote locations. This data is used to track efficiency and trends, plan maintenance schedules, report the power produced and predictive information to the Independent System Operator critical to “Smart Grid” technology

Abstract: Voice communication becomes ineffective in the industries & various places where there is a noisy environment. Industries and other places which offer ineffective voice communication require data transmission in text and image form. The first approach of the project is to draw the pattern on touch screen display which is interfaced with arm7 processor and transmit this pattern using zigbee transmitter. At the receiving side ARM7 processor is interfaced with GLCD (Graphical Liquid Crystal Display) which displays the received pattern. The second approach is to send the bitmap images to the receiver. The bitmap images are stored in the ARM-7 processor‟s inbuilt EEPROM memory at the transmitter side. The touch screen display along with the GLCD is connected to the ARM7 LPC2148 controller. The ARM processor which is programmed to read the touched values in the real time environment, encode it and sends it to receiver. Whatever the information we want to send is accessed with the help of touch screen and ARM-7 processor and then it is showed on the GLCD at the transmitter. After that we can transmit that image or pattern to the receiver via zigbee transmitter circuit. This project is designed around the ARM-7 processor. The processor fulfils all the requirements related to wireless control and image processing. An inbuilt EEPROM is provided to store the bitmap images.

Abstract: The accurate measurement of the lumen intima and media adventitia interfaces thickness is very important to find any kind of cardio vascular diseases that are progressing and present in the carotid artery, this can be achieved robustly by measuring and identifying the intima and media thickness, which also represents any kind of future cardio vascular diseases. Here we try to develop an algorithm that will automatically help in the analysis of the carotid artery by segmentation and tracking of the arterial thickness that will consider the B-mode video sequence of the ultra sound scan. In the first stage of the proposed algorithm the tracking and segmentation procedure is done and in the second stage a new technique called adaptive normalization correlation procedure is applied which helps the next coming frames to automatically adapt to the reference frames. This procedure is applied for one full cardiac cycle, the proposed algorithm using the automatic segmentation and tracking of the intima and adventitia thickness uses the adaptive normalization correlation technique is of very high clinical relevance importance and will provides the expected accurate result.

Performance Evaluation of AOMDV & MPOLSR Routing Protocol for MANET
Rohit Jain, Sourabh Jain, Mukesh Patidar, Piyush Agrawal
DOI: 10.17148/IJIREEICE.2015.3554
Abstract: A mobile ad hoc network (MANET) is a collection of wireless mobile nodes communicating with each other using multi-hop wireless Links without any existing network infrastructure or centralized administration. In recent years, a variety of routing protocols targeted specifically at this environment have been developed and some performance simulations are made. Multi-path routing has been studied thoroughly in the context of wired networks. It has been shown that using multiple paths to route messages between any source-destination pair of nodes (instead of using a single path) balances the load more evenly throughout the network. The common belief is that the same is true for ad hoc networks, i.e., multi-path routing balances the load significantly better than single-path routing. Our Protocol, called MP-OLSR & AOMDV is a multipath routing protocol. In addition route recovery & loop detection are implemented in MP-OLSR in order to improve quality of service regarding OLSR.MP-OLSR is suitable for mobile, large & dense network with large traffic & could satisfy critical multimedia applications with high on time constraints.

Contingency Ranking in Modern Power System by Exact and Precise Method

Abstract: One of the important aspects of modern power system security assessment is the consideration of any contingencies arises due to unplanned or planned line outages leading to system overloads or abnormal system voltages. Several methods have been developed in the past few years to address this problem but computation time has been identified as the constraint making the process inefficient. Utilities today are in need of tools, techniques and also the methods that will enable them to predict the dynamic stability and reliability of the grid in the real-time. A power system is secure against a given contingency if it operates within tolerable operating limits before and after the occurrence of the contingency. In practice, it is not possible to secure a power system against all possible contingencies. Therefore, only the most critical contingencies (imminent disturbances) are considered. Contingency ranking attempts to estimate the impact of various contingencies without actually solving the power network. Existing methods of contingency ranking methods suffer from masking effects in approximate methods and slow execution in more accurate ranking methods. This paper presents an exact and precise method of contingency ranking. The method used here takes due consideration of both apparent power overloading and voltage violations simultaneously to find indices which in turn used to rank the contingencies. Here 1P1Q solution is used to find the post contingency voltages and power flows. The proposed work is simulated on IEEE-14 and IEEE- 30 bus test systems in MATLAB environment. The method used is based on realistic approach taking practical situations into account. Besides taking real situations into consideration, this method is fast enough to be considered for on-line security analysis.

Abstract: Antennas are key components of any wireless communication system. Patch antennas are widely used as they offer low-profile designs for a wide range of wireless applications. The design of circular patch antenna is presented in this paper and the simulated results are compared with the general well-known results of antenna’s performance incorporating its radiation property, gain, port characteristics and s-parameters. The optimum gain was observed at the substrate thickness of 0.35mm and here the return loss (S11) is -22dB but return loss is still good at radius of patch 21.5mm with increasing gain. Modelling was done using backpropagation algorithm (KBNN) and simulations were done using HFSS.

DOI: 10.17148/IJIREEICE.2015.3558
Abstract: Queuing theory employs mathematical analysis to determine the system's effectiveness measures. Such critical and effective measures are then used as data in the development of an optimization model for determining system efficiency and requirements. In this paper, we will discuss and provide the steps for developing the computer simulation model as well as the mathematical algorithms required to analyse the complex service network as queuing systems. A computer simulation is a realistic simulation of how a real-world process or system works over time. It is a very useful and valuable tool for analysing and evaluating any available or developed process. It can be used to learn, test, and evaluate the behaviour of many different types of problems. Simulation provides a low-cost, secure, and quick analysis tool with the necessary sensitivity analysis.
