Abstract: Artificial intelligence is the science of automating intelligent behaviours currently achievable by humans. Power system has grown tremendously over a few decades. As the size and complexity of the power system consisting of generators, transmission lines, power transformers, distribution transformers etc. increases the possibility of inviting faults. The acquisition of data, the processing of those data for use by the operator, and control of remote devices are the fundamental building blocks of all modern utility control systems. Manual calculations, technical analysis and conclusions initially adopted the power system design, operation and control. As the power system grew it become more complex due to the technical advancements, variety and dynamic requirements.

Keywords: Artificial intelligence, Expert system, Artificial neural network, Fuzzy logic, Power station.
