摘要

随着分布式电源在低压配电网中的高度普及，一些电能质量问题，如电力电子变流器的谐波影响，是不可避免的。本文分析了DG逆变器对电网连接点和其他节点的谐波影响。利用MATLAB/Simulink建立了含DG逆变器的低压配电网模型。仿真结果验证了分析的正确性。介绍了现场测量中多台DG逆变器接入低压电网时的接入点电能质量问题，并对相关问题进行了讨论。

Harmonic impacts of inverter-based distributed generations in low voltage distribution network

With the high penetration of distributed generations (DG) in low voltage (LV) distribution network, some power quality problems, such as harmonic impacts due to power electronics converters, are unavoidable. This paper analyzes the harmonic influence caused by DG inverters to the connection points and to other nodes in the network. The LV distribution network model with DG inverters is established by MATLAB/Simulink. And simulation results verify the analysis. Power quality issues of connection point when multiple DG inverters connected to LV network are presented in field measurements and some related problems are discussed.
