Abstract

One of the major objectives of any electricity supply authority is to be able to supply its customers the quality product and meeting their demand at all times. One major setback in achieving this object in Nigeria is the incessant outages on the grid generator buses and transmission lines. System security involves the practices designed to keep the system operating when components fail. System security analysis involves three major analyses. These include system monitoring, contingency analysis and corrective action. In this work a D.C power analyses. In this work a D.C power flow mathematical technique has been employed to carry out contingency analysis using NEPA 28-bus Nigeria 330kv national grid network. Simulation of the effects of the outages were carried out on the network. Executed one by one, outages were introduced on two generators buses and on three transmission lines of high loading capacities. With the contingency analysis performed s explained mathematically in section 2 of this paper, the new power flows when outages were introduced are presented graphically in figures 4 and 5. Results showed that new flows (MW) went up beyond limit values on some of the lines during the outages.
