摘　　要：静止变频器(Static Frequency Converter,SFC)是抽水蓄能机组变频启动的核心设备。为研究静止变频器在运行过程中损耗特性,分析了SFC主要功率部分包括晶闸管阀组和直流平波电抗器的损耗计算方法。利用开关器件和直流平波电抗器厂商提供的相关数据,对某抽水蓄能工程静止变频器损耗进行计算。结果表明损耗计算值与实测值相近,可为静止变频器冷却容量配置提供参考。Static Frequency Converter(SFC)is the core equipment for variable frequency start-up of pumped storage units.In order to study the loss characteristics of SFC during operation,this paper analyzes the loss calculation method of the main power parts of SFC including thyristor valve bank and DC smoothing reactor,and then uses the relevant data provided by the manufacturers of switching devices and DC smoothing reactors to calculate the loss of SFC in a pumped-hydro energy storage project.The results show that the calculated loss is close to the measured loss,which can provide a reference for the cooling capacity configuration of Static Frequency Converter.
