一、基本概况和效益的分析湖南东安县湘江水轮泵水电站,根据地形特点,裁弯取直,拦河筑坝,取得总水头14米,安装7台60—6型水轮泵。分高低两灌区,高灌区总扬程42米,灌田9000亩,低灌区总扬程21米,灌田2000亩,同时又利用湘江丰富的水力资源,安装了发电机组3200瓩6台、125瓩1台、250瓩2台、55瓩2台,总装机容量19935瓩,设计年平均运行5100小时,年发电量1.01亿度。实际年运行4257小时,年发电量8487万度,年收入电费649万元。全县的用电负荷由1978年的790万度到1989年达8487万度,增长10.74倍。湘江水轮泵、水电站的建成,不但为灌
First, the basic situation and benefits of analysis Xiangtan Hydroelectric Pump Station in Dongan County, Hunan Province, according to the characteristics of the terrain, cut straight, river dam construction, made a total head of 14 meters, the installation of seven 60-6-type water pump. Divided into two levels of irrigation, high irrigation area of 42 meters total head, 9,000 acres of irrigated fields, low irrigation area total lift of 21 meters, 2000 acres of irrigated fields, while the use of the Xiangjiang River rich water resources, installed generator sets 3200 瓩 6 units, 125 瓩 1 Taiwan, 250 瓩 2 sets, 55 瓩 2 sets, with a total installed capacity of 19935 瓩, designed to run an average of 5100 hours, the annual generating capacity of 101 million degrees. The actual annual operation of 4257 hours, annual generating capacity of 84.77 million degrees, the annual income of electricity 6.49 million yuan. The electricity load in the county increased from 790 million degrees in 1978 to 84.87 million degrees in 1989, an increase of 10.74 times. Xiangjiang water pump, hydropower station built, not only for irrigation
