抽水蓄能电站在混合电力系统中的经济效益分析

Analysis of Economical Benefit of Pumped-Storage Hydro-Plant in Hybrid-Type Electric Power System

混合电力系统运行应满足电力平衡与调峰能力平衡．引入机组调峰能力系数人以ｆ＝－１的抽水蓄能机组加入系统电源构成较为经济．抽水蓄能机组参与电力系统运行的经济效益分析应以整个电力系统为对象．文章提出以上确定加和抽水蓄能机组容量值的计算方法及经济效益分析方法．系统开机构成中，抽水蓄能机组的加入改善了系统火电机组运行条件，使系统煤耗最省．文章提出了加入系统开机构成的抽水蓄能机组容量值确定方法．

The Operation of the hybrid-type electrical power system should satisfy the electric power balance and the equilibrium in peakload regulating ability as well. By leading in peakload regulating ability coefficient f and pumped-storage groups of that of f equate to negative one in the electrical powre system,we get the constitution of power source of system,which is more economical. The econmical benefit of putting pumpedstorage groups in the power system ought to compute for a whole power system. The artical put forward a caculating method which determines the capability value and economical benefit of putted pumped-storage in the system. It can ipmrove the operating condition of thermoelectricity set and can save coal consumpution to put pumped-storage groups in the drive set compositon of the system. The artical put formard a caculating method which determines the capability value of putted pumped-storage set in the drive set composition of the system.
