Practical Model of Wind Generator with Auxiliary Frequency Controller on PSS/E

Abstract

This paper studies the electromechanical transient modeling techniques of the wind generator with auxiliary frequency controller. Firstly, the operation condition of the wind generator which is required to provide frequency support to the system is analyzed. A calculation method is proposed to compute the tip speed ratio and the pitch angle for the given de-load coefficient and the real wind speed, which are the reference values for the dynamic simulation model. Then, the structure of the wind generator practical model is given. Lastly, cases of wind generator under disturbance is simulated for the validation of the proposed model.
