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。 With the rapid growth of power demand in Guangxi power grid, the peak load and trough difference is widening, and the system urgently needs peak regulation capacity. Firstly, the article expounds the necessity of constructing pumped storage power station in Guangxi Power Grid, and then uses the equivalent replacement method to analyze the capacity benefit, power (coal saving) benefit and environmental benefit of the pumped storage power station. By comparing with the cost of alternative thermal power plant Explain the economy of a pumped storage power station.
