Transient Stability Enhancement of Hybrid Power System with Wind Generator

Surbhi Sharma, Anant Thakur

Abstract: Flexible AC transmission systems (FACTS) controllers have been mainly used to solve various power system control problems. Many controllers of Flexible AC Transmission Systems (FACTS) like SVC, STATCOM, Unified Power Flow Controller (UPFC), PWM asynchronous dc link, Thyristor-Controlled Series Capacitor (TCSC) and PWM Series Static VAR compensator gives stabilized voltage support. So they can be placed at the mid-point of the transmission line, which has been proven by the late E. W. Kimbark, as the optimum location for shunt capacitor compensation. In this paper a shunt FACTS device (STATCOM) on transmission line to improve transient stability with predefined real power flow. Voltage stability is a key issue to achieve the uninterrupted operation of wind farms equipped with squirrel cage induction generators (SCIG) during grid faults. A Static Synchronous Compensator (STATCOM) is applied to a power network which includes a SCIG driven by a wind turbine, for steady state voltage regulation and transient voltage stability support. The system is implemented using MATLAB/ SIMULINK. Results illustrate that the STATCOM improves the transient voltage stability and therefore helps the wind turbine generator system to remain in service during faults.
