Abstract: Contingency analysis is the essential characteristic of the Power system security. The security evaluation is a crucial venture because it offers the statistics regarding the system state within the occasion of a contingency. Contingency analysis technique is being widely used to are expecting the result of outages like failures of kit, conductor etc, and to require essential movements to live the facility device cozy and dependable. The off line evaluation to expect the effect of contingency might be a dreary mission as an electricity device includes massive range of components. A choice of techniques of contingency analysis had been given in this paper and moreover the usage of artificial neural network for contingency analysis has been done.
