General situation of Baishi hydropower station project

Baishi Hydropower Station is one of the cascade hydropower stations in Qingshui River, located in Tianzhu County, Qiandongnan Prefecture, Guizhou Province. The dam site is located in Pingnei Village, about 2.8 kilometers upstream of Baishi Town, Tianzhu County, and 30 kilometers away from Tianzhu County. The dam is 68 meters high, the normal water level of the reservoir is 300 meters, and the installed capacity is 420,000 kilowatts. The static total investment of the project is 3.206 billion yuan. Mainly for power generation, with comprehensive benefits such as flood control, shipping and aquaculture. The inundation involved more than 22,000 people in 30 villages and 2 neighborhood committees in five townships, namely Kengchu, Zhu Lin, Yuankou, Shexue and Baishi in Tianzhu County, and flooded three market towns, namely Kengchu, Yuankou and Xinglong. The project started in 2003, was listed as a key project in Guizhou Province in 2005, and was approved by the National Development and Reform Commission on March 18, 2008. It is planned to be completed and put into operation by the end of 20 10.

The main task of power plant is to generate electricity, which has comprehensive utilization benefits such as shipping; The dam crest elevation is 304.5m, the normal water level of the reservoir is 300.00m, the dead water level is 294.00m, and the regulated storage capacity is 654.38+72 million m3, which has seasonal regulation performance. The upper part is 56.3km from Hangzhi cascade and the lower part is 56.2km from Tuokou cascade. The dam site controls the drainage area 16530 km2, accounting for 93.8% of the total drainage area of Qingshui River. The average annual runoff for many years is114.8 million m3. Three Francis turbine generator sets are installed in the power station, with a single capacity of 140MW and a total installed capacity of 420MW;; 3 main transformers with rated capacity of 160MVA; Two 500 kV lines, one connected to Sanbanxi Hydropower Station, 67 kilometers away from our factory, and the other connected to Yanshan Red Switch Station, 32 kilometers away from our factory; The designed annual average power generation is 65.438+23.6 million kWh. After the completion of the power station, it will be connected to Hunan power grid to undertake the tasks of peak regulation, frequency modulation and emergency standby.

Baishi Hydropower Project is the largest investment project in Tianzhu County. In April 2003, the People's Government of Qiandongnan Prefecture successively signed the Letter of Intent for the Construction of Tianzhu Hydropower Station and the Framework Agreement for the Construction of Tianzhu Hydropower Station with Wuling Company. In order to do a good job in power station construction and resettlement, Tianzhu County Immigration Development Bureau was established in August of the same year. In 2004, Baishi Power Station was listed as the first of "Ten Practical Things" by Tianzhu County Party Committee and County Government.

Since September, 2003, the preparatory work for power station construction has been carried out in an all-round way, and the preliminary works such as the approach road of Baishi Power Station, 1 10 kV substation, site leveling works in the construction area, flood dike works of Dongjiaqiao, gravel yard and Baishi Bridge have been completed one after another. Two centralized resettlement sites, Sam 'ao in Baishi Town and Dongjiaqiao in Jiangdong Township, were implemented to resettle 85 households with 3 14 people in the construction area; The investigation, review and publicity of submerged physical indicators in the reservoir area of Baishi Power Station were completed, and the decomposition, publicity and review of submerged land in the reservoir area were carried out, as well as the investigation of the current situation of market towns and homesteads. At the same time, the reconstruction planning and design of three relocated market towns, Machu, Yuankou and Xinglong, and the planning and design of special reconstruction projects such as transportation, electricity and communication in the reservoir area were completed. In June 5438+February, 2008, the construction access road of Luohanpo Precast Yard Project of Qingshuijiang Bridge in Yuankou and Qiutangwan Bridge of Baishi-Xinglong Highway were started one after another, marking the comprehensive start of the reservoir management project. By the end of 2009, the investment of the completed project was nearly 654.38 billion yuan, and the compensation investment was 42.4433 million yuan.
