Abstract

This paper studies system stability of wind farms based on fixed speed induction generators (FSIG) and investigates the use of the static Var compensator (SVC) and static synchronous compensator (STATCOM) for wind farm integration. Due to the nature of asynchronous operation, system instability of wind farms based on FSIG is largely caused by the excessive reactive power absorption by FSIG after fault due to the large rotor slip gained during fault. Wind farm models based on FSIG and equipped with either SVC or STATCOM are developed in PSCAD/EMTDC. It was found that the SVC and STATCOM considerably improve the system stability during and after disturbances, especially when the network is weak. Compared to SVC, STATCOM gave a much better dynamic performance, and provided a better reactive power support to the network, as its maximum reactive current output was virtually independent of the voltage at the point of common coupling (PCC).
