故障树在光伏并网系统失效研究中的应用

Fault Diagnosis in Solar Photovoltaic Grid-connected Power system Based on Fault Tree

本文提出一种基于故障树理论的故障诊断方法,通过定性和定量的系统综合分析提出效率比的概念,据此确定故障诊断的最优排序,从而进行并网光伏系统的故障诊断,实例证实此方法是可行的。

This paper proposed a new fault diagnosis method based on fault tree. A new Concept, ratio of efficiency, was carried out by qualitative and quantitative analysis. According to the concept, it can find the best method to diagnose all the system and remove the faults. An illustrative example demonstrates that the method is execution.
