光伏小区的电能质量治理方式

Suppression Method of Power Quality in Photovoltaic Community

介绍了海宁市光伏小区光伏发电系统存在的电能质量问题,分析了光伏小区的电能质量治理方式,采用的有源型电能质量治理装置能解决并网系统三相不平衡电流、无功补偿以及谐波电流问题,提升光伏并网系统的供电质量,保证无功补偿柜的正常运行,提高变压器和配电线缆的带载能力。

This paper introduced the power quality problems of photovoltaic power generation system in photovoltaic community of Haining,and analyzed the suppression method of power quality. The active power quality control device can solve the problems of three phase unbalance currents,reactive compensation and harmonic current,which improves the power supply quality of the photovoltaic grid-connected system. It ensures the normal operation of reactive power compensation cabinet,and Improve the carrying capacity of transformers and distribution cables.
