摘　　要： 对于风电场中失速型机组的多机等值,采用异步发电机的机电暂态模型求解发电机组的等值电气参数,利用基于传递函数概念的参数辨识方法及最小二乘法求解发电机组的动态等值参数。利用系统等值得结果对一实例进行仿真,结果表明了等值方法的有效性和正确性,为今后研究风电场与电网之间的相互影响提供了良好的模型基础。 The equivalent characteristics of multiple fixed wind turbine units were discussed. A electro-mechanical transient model of induction machine was used to obtain the system equivalent electrical parameters. Parameter identification method based on transfer function and least square method was used to solve the equivalent dynamic characteristics. The equivalent parameters were applied to simulate an example wind farm. The simulation results proved the effectiveness and correctness of equivalent method used in this paper. This research provided a favorable model basis to study the impact between wind farm and electrical network in the future.
