Abstract: Viewed from static voltage stability, by using PV curve method, and index of active power margin and voltage-active power sensitivity, this paper gives mechanism analysis of influence of wind power on grid voltage stability. Also, affection of reactive power from wind farm and local grid strength on the former index is analyzed, result shows that increasing reactive power support and strengthening power grid could improve grid static voltage satiability effectively. A wind power congregation system in China area is simulated to verify the theory, at last, some measurements to improve voltage stability are proposed.

Key words: wind farm, static voltage stability, PV curve, stability index
