Dynamicmodelsimulationofdoubly-fedwindturbines
为满足在电网发生故障时风电机组需保持与电网连接并向系统不间断供电的要求,提出
了双馈风力发电机的动态模型、变流器模型、变流器保护及电网模型,以研究双馈风力发电机的暂
态特性.以1·5MW SUT-1500双馈风力发电机为原型,由一个无穷大电源等效电网模型,变流器模
型采用定子磁链的定向电流矢量控制方法,利用PSCAD软件对双馈电机的暂态特性进行仿真.仿
真结果表明,矢量控制能够实现双馈电机的有功、无功解耦,并可改善系统的低压穿越能力.
(To meet the power failure to keep their wind turbine grid-connected uninterruptible power supply to the system requirements, proposed doubly-fed wind turbine dynamic models of converter model, inverter protection and network model to Study of double-fed wind generator transient characteristics. to 1.5 MW SUT-1500 double-fed wind turbine prototypes, by an infinite power grid equivalent model of converter model uses the stator flux orientation of current vector control methods, using PSCAD software to double-fed motor simulation of transient characteristics. The simulation results show that vector control can be achieved double-fed motor active and reactive decoupling, and can improve the system through the capacity of low-voltage.)
