摘　　要：首先分析了风电系统能量转换原理,得出最大功率控制的理论依据。在最大功率控制理论的基础上,采用脉宽调制技术控制发电机输出平均电压,从而以间接控制发电机转矩的方式实现最大功率追踪。研究工作根据理论分析,搭建了风力发电机组功率测控平台,平台具有测试和根据测试进行控制两大功能,为风电机组的设计和研发提供了试验手段。试验证明,该文所采取的控制原理方法正确,搭建的试验平台能够实现预期目标。The energy conversion principles of wind power generation system were analysed, and the maximum power control theory was obtained. The pulse-width modulation technology was adopted to regulate the mean generator output voltage based on maximum power control theory, and the generator torque was indirectly controled to achieve maximum power tracking. The wind turbine power measurement and control platform was built based on the torque controlled indirectly according to theoretical analysis. The platform has dual functions of testing and control, and provides a test means for wind turbine design and R ＆ D. The test results show that the method of control is fight and the test platform can achieve the desired objects.
