Contingency Analysis of the Nigeria 330kv Post-Reform Integrated Power System Using Power World Simulator

With the Nigeria Power Sector going through reforms, it is very important to be able to predict the extent of violations that can occur in the network in the event of unprecedented contingencies. This is usually achieved through contingency analysis of the network in order to make for adequate provision of infrastructure to ensure system security in event of such contingencies. In this paper, single line contingency analysis for the Nigeria 330kv post-reform grid to determine violations in the network due to the individual contingencies were considered using power world simulator. The simulation result indicates that with generator contingency at mambilla, there were six bus violations with a maximum per unit voltage of 1.166. There were also seven bus violations for Jos-Gombe and Damaturu-Mambilla line contingencies with minimum per unit voltages of 0.921 and 0.399 respectively.
