电力系统中水火电装机比例问题探讨

The Capacity Proportion of Hydropower to Thermal Power in Power Systcm

本文从电力系统供电可靠性和运行经济性角度出发，探讨了水火力系统中水火电装机的全哽比例，得出了相应的计算公式。最后结合西北和陕西电网的电源结构进行了实例分析计算。

From the reliability of power supply and economic operation in power system,the optimumcapacity proportion of hydropower to thermal power has been discussed with computing formula,Andwe apply it to practical problems of Northwest Power System and Shaanxi Power Network.
