摘要 本文分析研究了风电系统中常用的三种大功率变流器的拓扑结构,提出了一种基于变频器并联扩容技术的大功率风力发电变流器系统,系统以DSPIC30F6010A单片微机为控制核心,利用其内部集成的串行CAN接口,实现模块之间的同步控制。重点介绍了系统的原理及实现方案,给出了关键电路原理和实验波形。实验结果表明,系统很好地解决了MW级大功率风力发电机组的控制问题,有效的保证了系统的稳定运行。 In the paper,we study the wind power system in common use of three kinds of high power converter topology,and a kind of high-power wind-driven generator converter system based on parallel expansion technology is introduced,which has a control core of DSPIC30F6010A single-chip computer and uses its internal integrating serial CAN interface to realize synchronization between modules.the paper also introduces the principle and implementation of system project and give the key circuit principle and experimental waveform.Experimental results show that the system solves the problem of MW level high-power WTG control,guarantee the stable operation of the system.
