English Description：
Application backgroundIn power system contingency analysis is used to find weak buses in the system. By finding weak buses prediction can be made about outage (line outage or generator outage). There are many methods for performing contingency analysis. Performance index method is one of the most widely use method. Key TechnologyCoding is done on Matlab. Newton Raphson load flow. IEEE bus system. Contingency, performance index. Y-bus. Simulink model.
