Comparative study of STATCOM and SVC for wind farm performance enhancement application

The connection of large wind farms to the electrical network is a challenge for transmission system operators and for wind farm developers. Main intention of the grid connection is that the wind farm and the electrical network operate in a safe and reliable manner during steady state as well as during fault conditions. This paper, describes how active-stall, fixed-speed wind farms affect grid voltages and how faults in the connected transmission system impacts on these wind farms. Additionally, the effect of FACTS (STATCOM and SVC) on fixed-speed wind farm performance is investigated.
