Abstract
The Performance of Unified Power Flow Controller (UPFC) on Fault Current Limitation in a 330kV Power Network. The SIMULINK model of the Nigerian 330kV system was developed and the model of the UPFC was developed and integrated into the power system model. Results from simulation carried out showed the versatility of the UPFC in the protective limitation of excessive fault current in the system. Evaluation carried out indicated that the UPFC achieved an effective average of 59.23% fault current limitation. This result was shown to have high impact for the protection of critical assets within the power system such as circuit breakers. At a fault impedance of 0.0001Ω, the UPFC provided a 45.81% protection margin for the type of high voltage circuit breakers used on the 330kV system. Apart from interrupting capacity of circuit breakers, this action of the UPFC would also help to increase the life expectancy of circuit breaker contacts between overhaul.
