摘　　要：串补装置首次应用于750 kV电压等级,其设备庞大,结构复杂,对电站内电磁环境影响较大。为了使750 kV串补工程的电磁环境满足标准要求,研究基于沙洲—鱼卡、柴达木—海西—日月山750 kV串补装置的初步设计图纸,建立了单相串补、三相串补和2套串补的模型,结合西北二通道串补工程可能的环境条件,分别对海拔3 000 m和3 500 m下的模型进行详细的有限元计算,计算结果表明,初步设计下串补装置的电场强度满足标准要求。The series compensation（SC） device is applied to the 750 kV voltage class for the first time. its huge equipment and complex structure had great influence on the electromagnetic environment of power station. In order to correspond to the electromagnetic environment standard of 750 kV SC project,based on the studies on the preliminary design of 750 kV SC devices of Sha Zhou-Yuka,Qaidam-Haixi-Riyueshan,single-phase SC,three-phase SC and two sets of SC models is built. With the consideration of possible environment conditions of the two-channel series compensation project in Northwest China,a detailed finite element calculation is made under the 3 000 m and3 500 m altitude models respectively,and the results shows that electric field strength of the preliminary design of SC device met the standard requirements.
