摘　　要：文章阐述了风力发电的主要环节和基于PWM变流器的变速恒频控制技术。测试结果表明:风力发电机组PWM变换器协调控制是有效的,在电网侧逆变器中对输出有功功率和无功功率进行控制,使送往电网的有功功率跟从最大风能俘获曲线,达到最大功率俘获的目的。This article describes the main links of wind power generation and the variable-speed constant-frequency control technology based on PWM converters.The test results show that the coordinated control of the PWM converters of the wind turbines is effective.The output active power and reactive power are controlled in the grid-side inverter,so that the active power sent to the grid follows the maximum wind energy capture curve to achieve the purpose of maximum power capture.
