Reservoir area of Gongtong Hydropower Station

Gongtong hydropower station is located on Dadu River, a tributary of Minjiang River in Sichuan Province, 90 km away from Leshan City. The power station is mainly power generation. According to the plan of "high dam design and low dam construction", the project is constructed in two phases, with an installed capacity of 700 in the first phase, and two underground power plants behind the dam and on the left bank. The installed capacity of the powerhouse behind the dam is 400. The installed capacity of the underground powerhouse is 300. The guaranteed output of the whole plant is 179, and the average annual power generation for many years is 341.8 billion. Four 220 voltage transmission lines are connected to Sichuan power system, which is the main peak shaving hydropower station in the system. The main dam is a concrete gravity dam with a crest elevation of 5305m and a maximum dam height of 855m. The first phase of the project was started in March 1966, the first generating unit in February 1972 and completed in 1978. The specific scheme of phase II project is to be determined. Hydrological and reservoir characteristics: the drainage area above the dam site is 76130 square kilometers, with an average annual runoff of 472.5 billion cubic meters, an average annual runoff of 1500 cubic meters per second, and an average annual sediment discharge of 29.9 million tons. The normal water level of the reservoir in the first stage project is 528m, the dead water level is 518m, and the total storage capacity is 33.9 billion cubic meters. The dam is designed according to the once-in-a-thousand-year flood, with a peak discharge of 13700 cubic meters per second and a water level of 5288 meters; the dam is checked according to the once-in-ten-thousand-year flood, with a peak discharge of 15800 cubic meters per second and a water level of 5306 meters. The design head of the power station is 48m, the maximum head is 5308m and the minimum head is 347m. Travel is not moving, comments first.
