Voltage Stability Enhancement of Fixed Speed Wind Energy Conversion System

Abstract

Fixed speed wind energy conversion systems based on squirrel cage induction generator (SCIG) has a significant existence in wind energy technology. Availability of reactive power is obligatory for the reliable and stable performance of the power system. Insufficient reactive power has navigated to voltage collapses and has been a foremost source of various recent major power outages universally. This paper exhibits the simulation results of a grid integrated wind farm with and without reactive power compensation by capacitor banks and static synchronous compensator (STATCOM) to achieve voltage stability improvement during startup, normal operation, symmetrical and unsymmetrical fault conditions. The effect of reactive power compensation on voltage profile is compared.
