Series Active Filter For Self Excited Induction Generator Feeding Nonlinear Load
Abhishek Dubey , Suchi Mishra and Sachin Tiwari
Abstract
This article deal with series active filter (SAF) based controller to improves Power quality and voltage controlling a self-excited induction generator (SEIG) powered through a constant speed prime mover feeding a three phase nonlinear load. the continuously moving principal mover driven SEIG have problem of poor power quality and voltage regulation. The always-moving primary mover are a diesel motor, biomass, gas turbine etc. The voltage stabiliser is modelled utilising a voltage controlled voltage source converter (VCVSC) based on an IGBT (Insulated Gate Bipolar Junction Transistor) and a self-supporting DC bus. In series with the system voltage, the SAF is injecting a voltage. Utilising MATLAB, Simulink, also the with the help of the power system block set (PSB) toolbox, a 7.5Kw, 415V, 50Hz asynchronous generator-based generating system with SAF is developed and simulated. The reported simulation results show how an voltage controller-equipped asynchronous generating system can supply a changing consumer load.
