分布式电源并网中电能质量相关规范探讨

在介绍典型分布式电源并网方式的基础上,针对我国分布式电源的发展状况,结合分布式电源发达国家的经验,对基于电能质量问题考虑的分布式电源接入电网的相关规范进行了探讨。分析表明,包括电压偏差、电压波动、功率因数、负荷控制、解列方式、逆潮流、直流偏磁、谐波等问题应当在建立分布式电源并网电能质量相关指南中予以考虑。

Power Quality Standard Consideration for the Connection of Distributed Generation to MainGrid

Based on the circuit and control method of the connection of distributed generation(DG) with the main grid described,in light of the developmental status of DG in China,combining with the experiences of DG in the developed countries,the presented paper gives some suggestions on power quality problem consideration in the establishment of guideline for the connection of DG to main power system.The factors considered include voltage deviation,voltage fluctuation,power factor,load shedding,disconnection,inverse power flow,DC magnetic bias and harmonice etc.Suggestions are proposed according to the development of DG in China and with reference to the similar quidelines in the DG well developed countries.()
