地铁无功补偿装置SVG方案设计

The Design of SVG Scheme for Subway Reactive Power Compensation Device

地铁供电系统的无功补偿效果与电力系统的功率因数、电网电压水平、谐波等问题相关。文章研究了地铁供电系统各元件的无功功率及其计算公式,深入分析了动力照明系统的无功功率情况及各类负荷的无功百分比,并结合济南某线地铁供电系统的初步设计参数,讨论了SVG的无功设计方案,为地铁无功补偿方案的设计提供了技术支撑。

The reactive power compensation effect of the subway power supply system is related to the power factor,grid voltage level and harmonics of the power system.In this paper,the reactive power of various components of the subway power supply system and their calculation formula are studied.The reactive power situation of the power lighting system and the reactive power percentage of various loads are analyzed in depth.Combined with the preliminary design parameters of the subway power supply system of a line in Jinan,the reactive power design scheme of SVG is discussed,which provides technical support for the design of subway reactive power compensation scheme.
