摘　　要：对市域(郊)铁路供电系统无功补偿方案进行研究,提出3种无功补偿方案,包括常规35 kV侧SVG和电抗器的补偿方案、110(220)kV侧设置磁控电抗器(MSVC)和35 kV侧设置SVG的补偿方案、同相供电装置补偿方案;分析3种方案无功补偿的原理,并以某条线路为例,对比分析3种方案的安装容量、经济性和适用性,可为市域(郊)铁路无功补偿方案选择提供参考。Studies are made for the reactive power compensation schemes for power supply systems for urban(suburban)railway lines,and three reactive power compensation schemes are proposed accordingly,including compensation schemes for conventional 35 kV side SVG and reactors,compensation schemes for 110(220)kV side with magnetically controlled reactors(MSVC)and 35 kV side with SVG,and compensation schemes for co-phase power supply devices.The analysis is made on the principles of three reactive power compensation schemes.And comparison and analysis are also made for installation capacity,economic efficiency and applicability of the three schemes,providing reference for the selection of reactive power compensation schemes for urban(suburban)railway lines.
