本文在满足电力系统相同的电力、电量,并取得相同的社会效益基础上,计算电站每千瓦可用容量的投资(包括输变电投资),水电比火电静态高人民币607元,动态高1280元。但火电还应加上煤矿、运输等相关投资。当包括相关投资后,水、火电每千瓦可用容量的综合投资,无论是静态还是动态,都是火电此水电高。
Based on the same power and power consumption of the power system and the same social benefits, this paper calculates the investment (including investment in transmission and transformation) of available capacity per kilowatt of the power plant. The hydropower is 607 yuan higher than the static electricity of the thermal power station, with a dynamic high of 1280 yuan. However, thermal power should also add coal, transportation and other related investments. When including the related investment, the combined investment of water, thermal power available capacity per kilowatt, whether it is static or dynamic, is high in thermal power.
