摘　　要：以含笼型异步发电机组的并网风电场为例,在分析单机异步风力发电机动态模型的基础上,研究了风电场容量加权单机等值、降阶变尺度多机等值、参数变换单机等值以及改进加权单机等值模型和方法。针对风电场机组参数完全相同和不同的两种算例,利用Matlab/Simulink平台建立了风电场不同等值模型,对风速扰动和风电场出口处发生三相短路故障下的风电场动、暂态运行特性进行了比较分析,研究结果验证了等值模型的正确性和适用性。Based on a wind farm including wind turbines with squirrel cage induction generators （SCIGs）, different aggregated models of a wind farm, such as a single weighted average model, a reduced-order re-scaled model, a parameter transformed model and a single weighted arithmetic model were presented, as well as the detailed SCIG wind turbine model. Regarding for the two cases of a wind farm including SCIGs with identical parameters and dif- ferent parameters, the dynamic characteristics and transient performances of the presented wind farm using different aggregated models were studied and compared by using Matlab/Simulink, based on the conditions of the wind speed disturbance and three-phase short-circuit fault at the point of connected grid. The results have shown that the pres- ented wind farm models are correct and valid.
