Voltage Stabilization and Power Quality Enhancement of Wind Farms Using STATCOM

This paper considers the use of the static synchronous compensator (STATCOM) for wind farm integration. Wind farm models based on fixed speed induction generators (FSIG), using AC connection and equipped with STATCOM, are developed. Stability problems with the FSIG are described. An investigation is conducted on the impact of STATCOM ratings on system stability after network faults, and comparison is also made between the performances of wind generator with STATCOM and without STATCOM. Also impact of STATCOM on the wind speed variations and voltage sag is investigated. It was found that the STATCOM considerably improve the system stability during and after disturbances. And STATCOM improve the voltage sag cause by wind speed variation and fault conditions. It showed that the STATCOM gave a very good dynamic performance, and provided good reactive power support to the network, as its maximum reactive current output was virtually independent of the PCC voltage
