摘　　要：目前,钒液流电池是大容量蓄电池领域最新型的技术之一,需要依靠循环泵的动力运行,并对一些关键参数进行监控。全钒液流电池在运行过程中尤其是在充放电状态下决不允许循环泵停转,这就对钒液流电池监控系统的可靠性提出了极高的要求。首先对改进前的钒液流电池监控系统进行了结构分析,建立了监控系统结构图,并利用可靠性框图、故障树分析法、Blocksim软件对监控系统进行了可靠性分析,找出系统的关键点,并对关键点进行了改进,并通过改进前后的可靠性指标对比,表明改进后的监控系统的可靠性有明显提高。At present, vanadium redox battery is one of the latest technology in the large capacity storage battery field. Its normal operation needs to rely on the running of circulating pump, and to monitor some of its key parameters. When the vanadium redox battery is in operation, especially in charge and discharge condition, circulating pump is not allowed to stall. This sets high requirements to the reliability of vanadium redox battery monitoring system. This paper first analyses the structure of monitoring system of vanadium redox battery before improvement, and sets up structure diagram of monitoring system. By using reliability block diagram, fault tree analysis, Blocksim software, we make reliability analysis of the monitoring system, to find out the key points of the system, and then we try to improve them. Through comparison of reliability index before and after improvement, it is shown that the reliability of improved monitoring system has obviously been improved.
