《水力发电学报》1993年第三期刊登水力电力研究所陆钦侃的文章“我国经济可开发水能资源初步估算”。提出我国经济可开发水电装机容量为2.9亿千瓦,年发电量1.26万亿千瓦时。我国50年代估算的全国水能资源,只按各河流逐段平均流量和天然落差计算的理论水能蕴藏量,累计得5.4～5.8亿千瓦。77～80年对全国水能资源更全面的普遍,除再次核定理论水能蕴藏量为6.76亿千瓦、合年电能5.92亿千瓦时外,根据各河流规则或安排梯级开发共11000多座水电站,统计得全国可开发水电装机容量共计3.78亿千瓦,年发电量1.92千瓦时,相当于技术可开发的水能资源。1992年8月英刊《国际水力发电与坝工建设》刊登“世界水能资源”,列出了全世界各国的理论水能蕴藏量、技术可开发量和经济可开发量三个级别的水能资源,我国只有前两个数字,缺经济可开发量。
“Journal of Hydroelectric Power,” third issue of 1993 published in the Institute of Hydraulic Research Lu Qin Kan’s article “preliminary analysis of China’s economically exploitable hydropower resources.” It is suggested that hydropower installed capacity in our country should be 290 million kilowatts and annual power generation should be 1.26 trillion kilowatt hours. China’s hydropower resources estimated in the 1950s only totaled 54-580 million kilowatts, based on the theoretical water energy reserves calculated by the average flow and the natural drop of each river section by section. In the past 77 to 80 years, the hydropower resources in China were more and more universally recognized. In addition to re-verification of theoretical hydropower reserves of 676 GW and annual energy of 592 MWh, a total of more than 11,000 hydropower stations were developed in accordance with the rules of the rivers or the cascades. According to statistics, a total of 378 million kilowatts of hydropower installed capacity can be developed nationwide, with an annual generating capacity of 1.92 kilowatt-hours, equivalent to hydropower resources that can be developed technically. In August, 1992, “World Hydropower Resources” was published in the British edition of “International Hydropower and Dam Construction”, which lists three levels of theoretical hydropower reserves, technologically developable amounts and economically developable amounts in all countries in the world Can resources, our country only the first two figures, the lack of economic development.
