广西建设抽水蓄能电站必要性及经济性分析

随着广西电网电力需求迅速增长，负荷峰谷差日益扩大，系统迫切需要调峰容量。文章首先阐述了广西电网建抽水蓄能电站的必要性，而后采用等效替代法分析抽水蓄能电站的容量效益、电量（节煤）效益及环保效益，并通过与替代火电厂的费用比较来说明建抽水蓄能电站的经济性。

Analyse on the Necessity and Economy of building pumped-storage power station in GuangXi

With the fast increasing of power desire in Guangxi province and the enlarging of the load peak and off-peak difference, system needs peak regulation capacity urgently. This article describes the necessity for building pumped-storage for Guangxi power grid at first, and then analyses the capacity benefit, the electricity quantity （coal saving） benefit and the environmental benefit of pumped-storage power station by adopting the equivalent replacement method, and explains the e-conomy of building pumped-storage power station by comparing the expenses with that of building the replaced thermal power plant.
