摘　　要：静止无功发生器(SVG)为现阶段电力系统最先进的无功补偿技术,应用现场的种类、数量不断增多。由于现场原因或者SVG本体原因,运行中偶尔出现故障是难以避免的事情。目前,常规的故障信息是一些故障后的保护状态信息,如过压、过流、欠压等,这些信息已经不能满足快速分析、查找故障原因的需求。通过分析,设计了一种用于SVG的故障录波系统,其特点是借用SVG现有的各种功能模块,在不增加硬件成本的情况下,实现记录故障前后电网电压和SVG输出电流数据,并通过人机交互模块显示,为故障原因分析、查找提供重要信息。Static var generator(SVG)is the most advanced reactive power compensation technology in the power system at present,and the types and quantity of application sites are increasing.Due to site or SVG ontology reasons,it is difficult to avoid occasional failures in operation.At present,the conventional fault information is some post fault protection status information,such as over-voltage,over-current,under voltage,etc.these information can not meet the needs of rapid analysis and fault finding.Through the analysis,a fault recording system for SVG was designed,which was characterized by using various existing SVG functional modules to record the grid voltage and SVG output current data before and after the fault without increasing the hardware cost,and through the human-computer interaction module display,important information for fault cause analysis and search was provided.
