The Research Of Diagnosing Photovoltaic Building Fault Based On State Grid Distributed Photovoltaic Cloud Platform

SGCC invented State Grid Distributed Photovoltaic Cloud Platform (SG-DPCP) in 2018, which is the largest distributed photovoltaic public service cloud platform in China. Based on the power generation data of SG-DPCP, in use of Big Data analysis technology, this paper proposes a method to accurately diagnose the fault types of photovoltaic buildings.The effectiveness of this method is verified by a specific application study.
