大型山地光伏电站的电气故障排查与处理

建设大型山地光伏发电项目的主要特点有建设面积大、布置分散、施工难度大等,导致项目建设完成后,施工质量问题频发,电气故障较难排查处理,从而影响光伏电站发电量,因此提出一套系统的故障解决方案及预防措施,对于在建项目及已建项目的质量把控,有重要意义。本文对光伏电站存在的电气故障问题进行汇总分析,探讨故障的根本原因,并针对光伏发电场区常见的电气故障进行梳理形成一套完整的处理方案及预防措施,给已经建成的电站提供故障解决方案参考,并在新建光伏发电项目中予以避免。本方案已在某100MW大型光伏电站中得到了应用,并取得了理想的效果。

The construction of large photovoltaic power generation project construction of the main features of mountain area is large,scattered layout and construction is difficult,and so on,After the project was completed,construction quality problems occur frequently,and it is difficult for electrical fault screen processing.thus affecting photovoltaic power generation,therefore puts forward solutions to a set of system failure and preventive measures,for the quality of construction projects and projects have been built to control,has important significance.In this paper,the photovoltaic power station electrical fault problems of summary analysis,discusses the root cause of the failure,and photovoltaic power generation of the common electrical failure,especial comb form a complete set of treatment schemes and preventive measures,the plant has been built to provide fault solution for reference,and in new photovoltaic power generation project to be prevented.This scheme has been applied in a 100MW large-scale photovoltaic power station,and the ideal effect has been achieved.
