在当前和今后一个相当长的时间内,我国电力供需矛盾将十分突出。大力兴建新电站,无疑是解决问题的好办法,但国家经济形势严峻,在短时间内要筹措大量资金和物力,并非易事。而抓紧现有发电工程设备缺陷的处理,提高发电量,却往往用少量投资,即可取得较大的效益。本文所论及的纪村水电站,装机二台共34MW,1973年动工兴建,1977年通水发电,由于混凝土挡水坝存在严重缺陷,最初6年压低水头运行,1983～1984年,被迫2年停水停机不发电(见表1),对大坝进行处理,损失大量宝 At present and for a long time in the future, the contradiction between supply and demand of electricity in China will be very prominent. Vigorously building a new power station is undoubtedly a good way to solve the problem. However, it is not easy for the country’s economic situation to be harsh in order to raise a large amount of capital and material resources in a short period of time. But pay close attention to the existing power generation engineering equipment processing defects, improve power generation, but often with a small amount of investment, you can get greater benefits. This paper discusses the Jicun hydropower station, a total installed capacity of 34MW, started construction in 1973, 1977 water power generation, due to the existence of serious defects in concrete retaining dam, the first 6 years to reduce the head run, 1983 to 1984, was forced to 2 years Shutdown without power generation (see Table 1), the dam for processing, loss of a lot of treasure
