Abstract:

Power system is a large, interconnected and complex network. The security and stability is the most important factor for a system to work reliable. In order to make the system stable and secured the operator must minimize the outages occurring for this purpose contingency analysis is very important. The operator must have idea about violations that may occur in the system. So here work is done to identifying the weak links in the network by contingency analysis and then going to take necessary precautions to overcome the problem, i.e. strengthening the weak links. Mathematical model will outline the simulation done for identification of generator outages, transformer outages and transmission line outages so that contingency analysis and ranking has been done based on full AC load flow. Here generation outages and transmission line outages are of concern. This method is applied to the 35 bus system.
