The purpose of this work is to study an electrical power system called two-area system. This system examines the inter-area oscillations that occur between two separated areas (Area 1 and Area 2) connected through a weak tie-line. The project was divided into two studies: without and with power system stabilizer (PSS).
The system was built using a Real Simulation Computer Aided Design (RSCAD), in which a line-to-ground fault was applied to the bus tying the two areas. Using a Real Time Digital Simulator (RTDS) to plot the results, both the power transfer from Area 1 to Area 2 and the inter-voltage oscillations at the inter-area bus were monitored and plotted. The contribution of a PSS was applied to the original two-area circuit.
As a result of introducing PSS, an average of 52% reduction to low frequency oscillations of inter-voltage and power flow between the two areas was observed.
