摘要
控制系统使变速风电机组具有了诸多优越性能,同时也在很大程度上决定了变速风电机组的运行特性,准确模拟控制系统的工作特性是建立变速风电机组动态模型的关键。为此,以电磁暂态仿真软件PSCAD/EMTDC为平台,应用电机矢量控制原理与PI调节器串联校正等方法建立了基于双馈电机的变速风电机组控制系统,并依据变速风电机组控制目标的要求校验了控制系统性能,验证了控制系统的有效性。
The control system not only provides the variable speed wind turbine (VSWT) some avdantages but also decides its operating characteristics. Simulating the control system's performance accurately is the key of the dynamic modeling for VSWT. Based on the model library of PSCAD/EMTDC, the control system of VSWT is established using the method of vector control principle and serial correction of PI regulator, and the performance of which is verified according to the control requirements of VSWT. The results prove the validity of the proposed control system.
