Simulation of AC/DC/AC converter fed RLC series circuit with asynchronous generator using Mat lab/Simulink

This paper describes the simulation studies of a 3-Ø self-excited asynchronous generator (SEASG) fed RL load in conjunction with an AC/DC/AC converter fed series RLC circuit. An attempt has been made to analyze the current, drawn by the rectifier circuit due to changes in the inverter frequency and their effects on the terminal voltage of the generator have been studied in open loop control. The frequency variation of the inverter fed series RLC circuit emulate the phenomenon of an inductive, capacitive reactance and resistive effect at the point of common coupling (PCC) of the generator terminal. This methodology could be used to inject leading / lagging VAR into the self-excited induction generator network (stand alone power generator), used to extract the power from wind, solar, Mini/Micro hydro energy sources. The proposed system has been simulated using power system tool box in Matlab/Simulink software. An attempt has been made to study the performances of SEASG using simulation. The results have been discussed and also presented.
