Abstract

This study presents the investigation of the effects of the various types of asymmetrical faults on the Nigerian grid. Simulation of the different types of short-circuit faults was carried out on the network using Power World Simulator (PWS) to examine their effects on the bus voltages and currents. Load-flow analysis was also carried out on the existing 28-bus Nigerian transmission grid using Newton-Raphson algorithm in the run mode of the Power World Simulator. The study revealed voltage violations at several buses and voltage dip at some buses due to asymmetrical faults. This has an adverse effect on the power system stability. Prolonged faults could eventually result in power outages. Recommendations to minimise the effects of these asymmetrical faults are proffered to ensure good power system stability and prevent outages in the network
