摘　　要：首先从风力发电的数学建模说起。应用PSCAD/EMTDC软件,以风机各部分数学模型为基础搭建了变桨距风力发电系统模型。分别在恒定风速叠加阵风、随机风情况下,仿真变桨距风力发电机组的输出有功和无功以及发电机转速的变化。仿真结果表明变桨距风电机组具有良好的运行特性,为今后的建模和仿真研究提供一定的借鉴。The basic structure of the variable pitch wind power system model is established based on the various parts of the mathematical model using PSCAD/EMTDC software. The output active and reactive power of the variable pitch wind turbine as well as the speed changes of generator are simulated in the superimposed gust wind speed and in the constant random wind case, respectively. The simulation results show that the variable pitch wind turbine has good operating characteristics, which gives a reference for the future modeling and simulation research.
