摘　　要：为了获取更精准的双馈风机变流器暂态模型参数,保障风力发电联网运行仿真分析结果的准确性,满足新能源高占比电力系统的安全稳定运行要求,文中提出了一种输出响应误差驱动的参数辨识方法。根据双馈风机的机电暂态模型确定出待辨识的参数,实现了MATLAB与PSASP的循环调用,根据真实值下的动态响应曲线与辨识值下的动态响应曲线的误差最小来确定最终辨识值,并通过设置不同工况验证该辨识方法的有效性。In order to obtain more accurate transient model parameters of the doubly-fed wind turbine converter,ensure the accuracy of the simulation analysis results of wind power grid operation,and meet the requirements of safe and stable operation of the new energy high proportion power system,this paper proposes a parameter identification method driven by output response error.The parameters to be identified are determined according to the electromechanical transient model of the double-fed fan,and the interface technology between MATLAB and PSASP is developed to realize the cyclic call between MATLAB and PSASP.The final identification value is determined according to the minimum error between the dynamic response curve under the real value and the dynamic response curve under the identification value,and the effectiveness and universality of the identification method are verified.
