Abstract
Series compensation of existing transmission line is the effective way of transmitting remote power. However, series compensation leads to the serious destruction phenomena called Sub-Synchronous Resonance (SSR). SSR in conventional power plant is well documented in the literature, however very scant information is available in the literature about SSR in wind power plant (WPP). On 22nd October 2009, SSR event occurred at the Zorillo-Gulf wind farms, during this event, additional transmission facilities tripped and numerous crowbar circuits of WPP failed. Until this event, it was believed that type 3 WPP is immune to SSR. This incident has established that type 3 WPP is prone to SSR. Most of the work has been carried out to asses and mitigate the SSR in type 1 WPP. Very few papers carried out work related to SSR in type 3 WPP, hence study of SSR in type 3 WPP is necessary to provide comprehensive knowledge of this subject. This paper reports the study of steady state and transient SSR in series compensated type 3 WPP. A first bench mark model is adopted with type 3 WPP for SSR studies. In this paper the effect of different parameters like wind speed, size of WPP and fault location is studied using electromagnetic transient simulation in MATLAB/Simulink to study SSR in series compensated type 3 WPP.
