In this paper, measurement-based characteristic curves are developed for voltage stability and control at the point of interconnection (POI) between a wind farm and a utility grid. The procedure to obtain an effective Q-V curve from measurement data is proposed, and monthly Q-V curves are built. Each Q-V curve is created using the data corresponding to a very narrowly defined real power range so the real power can be considered constant as the conventional Q-V curve concept. The curve fitting tool box in MATLAB is used to realize the required fitting to develop mathematical equations. This paper paves a practical way to obtain mathematical functions to represent voltage stability characteristics of a particular wind farm.
