Real-Time Simulation of Frequency Control of 2.2 kW SEIG using Generalized Impedance Controller

An attempt to control the terminal voltage and frequency of a self-excited induction generator (SEIG) using a Generalized Impedance Controller (GIC) with the open loop control system is investigated in this work. GIC is realized with a voltage source inverter (VSI) and a coupling transformer. MATLAB/Simulink was used to create the SEIG-GIC model; the system is run at a steady state while being subjected to various load speed perturbations and the result of the simulation is observed and described in this study. The simulation work is validated using OPAL-RT-LAB (OP4510). The proposed technique can maintain the constant frequency of the SEIG in open-loop situations, under various load variations.
