摘要
在多个分布式发电装置与电网并网运行的条件下,提出了基于级联H桥型五电平变流器的分布式发电并网方式,并设计了功率电流双环控制方法的有功、无功独立调节控制系统。最后利用PSCAD/EMTDC仿真软件对其进行了仿真分析,结果表明该系统功率控制灵活,电流波形极好。
With the grid-connected operation of multiple distributed and power network, the distributed generation grid-connected method based on cascade H .bridge five-level converter was put forward. The active and reactive adjusted respective system of power-current double-loop control was designed. At last, based on the software of PSCAD/EMTDC, the simulation analysis was done. The result showed that the system had flexible control and good waveform.
