SSSC WITH POD CONTROLLER FOR REACTIVE POWER COMPENSATION IN INDUCTION GENERATORS

One of the main problems faced by the Induction generator during fault is voltage sag. This phenomenon is really an undesirable one. The main aim is to introduce SSSC as a solution for this problem. It is connected in series for necessary compensation on its load side. To remove this problem it should be compensated by injecting a voltage in series so that it can provide necessary compensation. For that purpose we are using reactive power compensative devices (FACTS devices). Among the series connected FACTS devices SSSC is more preferred. It consists of a voltage source inverter (VSI). The series VSI is connected via a DC link, which includes a DC capacitor. The Induction generator is modeled using MATLAB SIMULINK is used for modeling of Induction generator. At that time of fault, power quality problems will dominate and active power is reduced. SSSC is used which will supply the necessary reactive power and thus the problem can be eliminated. This paper utilizes a SSSC with PWM generator and POD Controller for providing necessary control and thus for mitigation of power quality problems and hence reactive power compensation can be done which is the main objective.
