A Transient Preventive Control Method for Wind Power-DC Transmission System Based on Phase Trajectory Analysis Jia Fan, Zeng Yuan, Chang Jiangtao



In this paper, a transient preventive control method for wind power system, based on the information of generator power angle, angular velocity and voltage, is proposed. The objective function is the minimum of the total control amount. The required preventive control action can be efficiently solved via a linear programming model with the phase trajectory sensitivities-based constraints. The method aims to keep the online preventive transient stability with the wind power integration. The validity of the method is verified through 2DC system.
