摘要
风力发电机组变流器在风电机组结构中承担着电能转换的重要作用。针对两类并网风力发电机组,比较了一种被动整流变流器(I型)与一种主动整流变流器(II型)的优缺点,详细说明了两类变流器的拓扑结构与控制原理。依据IEC标准检测方法,通过现场试验,从整机角度对比研究了I型变流器与II型变流器电流谐波、间谐波、高频分量的释放水平及特征。试验结果表明,I型被动整流变流器与II型主动整流变流器电流谐波释放水平均符合并网要求,II型变流器电流谐波水平2.52%低于I型变流器3.44%。
The wind turbine converter plays an increasingly major role in energy conversion.This paper presented two types of grid-connected wind turbines,the advantages and disadvantages of active rectification converter I and passive rectification converter II are compared,and the topologies and control strategies for the two types of converters are illustrated as well.According to IEC detection methods,the emission levels and characteristics of current harmonics,inter-harmonics and higher frequency components of wind turbine with converter I and converter II are measured and studied respectively in the field.The test results show that the emissions of current harmonics is in compliance with the grid-connected requirements,and the current harmonics level of wind turbine with converter II is2.52%lower than3.44%of wind turbine with converter I.
