| 摘 要： | 对直驱式风力发电系统进行了相关研究,详细分析了风力发电系统中变换器模型,该系统由永磁直流电动机-发电机组、高功率因数整流器、全功率逆变器、滤波电路等组成,用直流电动机的端电压随时间变换引起的电机转速变化来模拟工程现场的风速变化,利用saber软件建立了整个仿真系统,并分析了整个系统中变换器的控制方式,仿真结果表明系统能够在不同风速下稳定运行,系统输出的电压近似正弦,谐波含量小,电能质量较高,同时也证明了系统模型的正确性和控制方式的有效性。

| Abstract: | The direct-drive wind power generation system based on permanent magnet DC motor was explored,and both of the sides of converter models of generator and power network were analyzed in details.The system consisted of a permanent magnet DC motor-generator set,a rectifier of high power factor,a boost converter and a full power inverter.The practical wind speed was simulated by the change of motor speed which resulted in the time-varying terminal voltage of the DC motor.The mathematical model of the system was ... |
