Abstract

The aim of the study is to simulate the model of a self-excited asynchronous generator (SEASG) feeding R L load in conjunction with an AC/DC/AC converter fed RLC series circuit connected at the Point of Common Coupling (PCC). Simulation model of the proposed system has been developed by using Matlab/Simulink. The result shows that the effect of RLC series circuit when operated at variable frequency affects the generation voltage profile. This reflects that an additional capacitance or inductance effect is possible to inject when the RLC is operated at a frequency lower or higher than the resonance frequency. This simulation model validates that the injections of capacitance in a SEASG are possible to match the lagging reactive power of the RL load to maintain a constant voltage at the load bus.
