ABSTRACT

This paper highlights the contingency analysis of Nigeria 330kV network to examine the risk of possible contingencies posed to the network under generators outage condition. The problems of the system in future are equipment malfunctions, under voltage at various buses, shortage of reactive power support, increased transmission losses and the tendency of system collapse. The design and simulation of the network was carried-out using power world simulator. The analysis was done using Newton-Raphson AC power flow method. Thereafter, three generators outage applied in the network was resolved using double circuit and reactive power compensation remedial actions. Consequently, a stable network that ensured adequate power delivery to the end users was achieved.


Keywords: Contingency Analysis, Power Flow, Transmission losses, Remedial actions, System collapse, Power world simulator
