基于矢量解耦控制策略，建立了适用于电力系统暂态稳定分析的直驱式风力发电机组机电暂态模型。为模型做了2 点合理假设：有功功率和无功功率在暂态过程中完全解耦；测量的电气量准确，和实际的电气量完全相等。基于这些条件，从实际的物理装置出发，对直驱式风电机组的电磁暂态模型进行简化。-Vector decoupling control strategy based on established for power system transient stability analysis of direct-drive wind turbine electromechanical transient model. As a model to do 2:00 reasonable assumptions: the active and reactive power in the transient process is completely decoupled　measuring electrical quantities accurate, and the actual amount exactly equal to the electrical. Based on these conditions, starting from the actual physical device for direct drive wind turbine electromagnetic transient model can be simplified.
