摘要
通过对轨道交通供电系统无功功率的分析,阐明了无功补偿容量计算应首先明确电能计量点和功率因数考核值,并应以线路运营初期负荷作为计算基础,紧扣月平均功率因数概念,并将低压有源滤波装置、逆变型再生能量吸收装置纳入无功补偿的一部分,以降低集中无功补偿安装容量,达到资源的合理配置。
According to the reactive power analysis of urban mass transit supply system, it was expounded that for the reactive power compensation calculation, the power quality evaluation point and power factor value should be clear firstly, and the average monthly power factor calculation with initial operation load should be based, also, the low-voltage APF and regenerative energy absorption effected on the reactive power compensation should be considered too, which helped to reduce the installation capacity of concentration reactive compensation and reach reasonable resource configuration.
