摘要
基于DIgSILENT/PowerFactory电力仿真软件建立了双馈感应发电机风力发电系统桨距控制数学模型、风力机数学模型和轴系数学模型,并对整个系统进行了仿真,模拟了有功功率、无功功率分别变化时以及网侧发生三相短路时整个系统的运行情况。仿真结果表明,该系统实现了功率的解耦控制以及在网侧三相短路情况下运行稳定,验证了模型的正确性,为风电场的仿真建模奠定了基础。
The paper established mathematical model of blade pitch control, wind turbine and shaft system of wind power generation system of double-fed induction generator based on DIgSILENT/ PowerFactory, and made simulation of the entire system. It also imitated operating of the entire system under variable active and reactive power and three-phase short circuit in grid. The simulation results indicated that the system realizes decoupling control of active power and reactive power and stable operation under three-phase short circuit in grid, and testifies validity of the models, which lays foundation for further research of modeling simulatiom of wind power field.
