浅析变电站及配电网电容器容量的合理配置

Rational distribution of capacitance of capacitors at substations and power distribution network

论述了并联电力电容器在无功补偿设备容量不足的电网中所具有的提高电压质量和降低损失的双重作用。通过分析变电站和配电网的结构和负荷特点,对如何进行合理的无功补偿及经济合理配置电容器等问题加以探讨。

The dual roles of improving quality and lowering losses of electric power capacitors connected in parallel in electric network without adequate power - off compensation capacity are described according to structures and loading of power distribution network. Rational power - off compensation and rational economic distribution of capacitors are discussed by analysing the structures and loading characteristics of substations and power distribution network.
