摘要
太阳能取之不尽,用之不竭,清洁安全,对于缓解日趋严峻的能源与环境问题具有重大的战略意义。随着太阳能光伏发电行业的发展,大量逆变型分布式光伏电源接入电网,光伏发电系统并网潜藏的故障逐步暴露。本文分析了工程现场光伏发电系统并网电弧放电和短路故障,然后提出了行之有效的纠正措施,解决了光伏发电系统并网故障,从而最大限度地节约维修费用和减少系统停机损失。
Solar energy is inexhaustible,inexhaustible,clean and safe,and has great strategic significance for alleviating the increasingly serious energy and environmental problems.With the development of the solar photovoltaic power generation industry,a large number of inverter-type distributed photovoltaic power sources are connected to the grid,and the potential faults of the photovoltaic power generation system are gradually exposed.This paper analyzed the grid-connected arc discharge and short-circuit faults of the photovoltaic power generation system on the project site,and then put forward effective corrective measures to solve the grid-connected failures of the photovoltaic power generation system,thereby maximizing the maintenance cost and reducing the loss of system shutdown.
