摘要
大规模分布式电源经变流器接入电网,对电力系统谐波问题的分析研究带来了新的挑战。针对分布式电源并网产生的谐波问题,研究了其产生原因及抑制方法。介绍了谐波的含义及其危害,分析了分布式电源并网产生谐波的原因,以及分布式电源并网产生的谐波与传统电网谐波的不同之处。重点分析了谐波的抑制措施,阐述了各种措施的原理、具体实施方法及优缺点。
As more distributed generations being accessed to power grid, it has a great influence on the harmonic studies of power system. Aiming at the problem of harmonic generated in distribution network with distributed generation（DG）,this paper studies its causes and suppression methods. First of all, it introduces the meaning of harmonic and its harm. Then it analyzes the reasons of harmonic generated by DG and the differences between harmonic generated by DG and traditional grid. Finally, it analyzes harmonic suppression measures, including the principles of the measures, how to do it specifically, and their advantages and disadvantages.
