What are the flood discharge structures of Dahua Hydropower Station?

The flood discharge structure of Dahua Hydropower Station consists of upstream approach channel, dam section, midstream channel, ship lift and downstream approach channel. According to relevant information, Dahua Hydropower Station is located in the middle reaches of Hongshui River, the main stream of Xijiang River in Dahua County, Guangxi Zhuang Autonomous Region, about 100km south of Nanning. It is the sixth cascade of Hongshui River 10 hydropower base in Nanpanjiang River, with Yantan Hydropower Station in the upstream and Bailongtan Hydropower Station in the downstream. Dahua hydropower station mainly generates electricity, which has the benefits of shipping and irrigation. The recent installed capacity of the power station is 400,000 kilowatts, with a guaranteed output of 6.5438+006,800 kilowatts and a multi-year average power generation of 2.65438+006 million kilowatts per hour ... After the completion of Tianshengqiao and Longtan Cascades in the upper reaches, the left-bank power station will be expanded with an installed capacity of 200,000 kilowatts, eventually reaching 600,000 kilowatts, with a guaranteed output of 343,000 kilowatts and a multi-year average power generation of 33/kloc-0. The reservoir flooded 489.2 hectares of cultivated land, with immigrants 1689 people. The project started in June 1975, the first power generation unit was generated in February 1983, and was completed at the end of June 1986.
