摘　　要：围绕全钒电池系统在部分失效条件下如何保持正常运行全面展开实验验证与理论分析。从电池系统结构组成角度分析了导致全钒电池系统失效的若干情况,并借助实验模拟和实验数据统计分析,总结归纳出全钒电池系统在部分失效条件下的运行特性,从而提出采用降额定功率与倍额定功率两种部分失效运行模式。研究证实该两种运行模式对系统运行效率无显著影响,是实现全钒电池储能系统在部分失效紧急情况下仍能保持正常运转的合理操作。This paper focuses on riding through cases when a VRB system is partially failed.A comprehensive experimental study and a theoretical analysis have been performed on such a case.Several failure situations have been considered and two operation modes are put forward to respond to the failure including the use of lower rated power and times rated power.The results indicate that two modes of operation for dealing with the VRB partial failure create no significant effect on VRB energy storage system efficiency,and hence providing a way to improve the reliability of VRB energy storage systems under emergency conditions.
