Who has the basic information of Fuchunjiang Hydropower Station?

Fuchunjiang Hydropower Station is located on Fuchunjiang River in Tonglu, Zhejiang Province, with a controlled drainage area of 365,438 0.300 square kilometers, an average annual flow of 65,438 0.000 cubic meters, a designed flood flow of 2,365,438 0.000 cubic meters, a total storage capacity of 874 million cubic meters and a designed irrigation area of 60,000 mu. The installed capacity is 297,200 kilowatts.

The dam type of the main dam is concrete gravity dam, with the maximum dam height of 47.7 meters and the crest length of 554.4 meters. The bedrock of the dam is rhyolite porphyry, and the dam works amount is 650,000 cubic meters. The main flood discharge mode is dam crest overflow. Fuchunjiang Hydropower Station is located on the Fuchunjiang River in the upper reaches of Qiantang River in Tonglu County, Zhejiang Province, and the dam site is at Qililong Xiakou, so it is also called Qililong Hydropower Station. It is about 60km away from Xin 'anjiang Hydropower Station and Hangzhou 1 10 km away. The geographical position is superior, and the Xin 'anjiang reservoir is used for regulation, and the two power stations are jointly operated, which provides a lot of electricity for East China Power Grid. The reservoir is regulated daily with a total storage capacity of 920 million cubic meters. Power stations mainly generate electricity, and can improve shipping, develop irrigation and aquaculture and other comprehensive benefits. The total installed capacity of the power station is 297,200 kilowatts, and the annual power generation is 923 million kWh. . Ship lock throughput 100 ~ 300 t, with an annual throughput of 805,000 t; With the irrigation canal head, the irrigation area in the lower reaches has increased by 60,000 mu.

The bedrock of the dam site is Cretaceous rhyolite porphyry and tuff breccia, with developed structure. The main structures of the hub include concrete gravity overflow dam, riverbed powerhouse, ship lock, irrigation canal head and fishway. See figure 13 for the layout of the hydropower station. The overflow dam section has a total length of 287.3m, the maximum dam height of 47.7m, continuous nose sill and surface flow energy dissipation. The workshop is a part of the water retaining structure, with the maximum height of 57.4m m. Four single-unit hydro-generator sets with a capacity of 60,000 kW and 6.5438+0 rotary-vane hydro-generator sets with a capacity of 57,200 kW are installed, and 65,438+065,438+00 kV and 220kV transmission lines are integrated into East China Power Grid. The fish heads are 158.57m long and 3m wide, which are arranged in a zigzag shape, forming a three-layer ladder for parent fish to lay eggs upstream. The ship lock is arranged on the right bank, the upper lock head is of water retaining gravity structure, and the working gate sinks. The irrigation canal is divided into left and right banks, and the diversion flow is 1.5m3/s and 5m3/s respectively. ..

Fuchunjiang hydropower station is a low-head riverbed power station. The normal high water level of the reservoir is 23 meters (Yellow Sea), with an area of 56 square kilometers and a storage capacity of 440 million cubic meters. The power station usually undertakes the tasks of peak regulation, frequency modulation and emergency standby in East China Power Grid. In order to make full use of water energy, it is necessary to bear a certain basic load in the wet season. By 1985, the total power generation of the power station1265438+50 million kWh, of which 1983 generated 999 million kWh, a record high. During the eight years after the five machines were assembled, the average annual power generation was 756 million kWh.

The reservoir is regulated every day. Power stations mainly generate electricity, and can improve shipping, develop irrigation and aquaculture and other comprehensive benefits. The total installed capacity of the power station is 297,200 kilowatts, and the annual power generation is 923 million kWh. Ship lock capacity 100 ~ 300 tons, annual dam capacity of 805,000 tons. With the irrigation canal head, the irrigation area in the lower reaches has increased by 60,000 mu.

The total length of the overflow dam section is 287.3 meters, and the maximum dam height is 47.7 meters. Continuous nose sill and surface flow are used for energy dissipation. The workshop is a part of the water retaining structure, with a maximum height of 57.4 meters. Four hydro-generators with a single capacity of 60,000 kilowatts and 1 rotary vane hydro-generators with a capacity of 57,200 kilowatts were installed, and the 1 10 kV and 220 kV transmission lines were incorporated into East China Power Grid. The fish heads are158.57m long and 3m wide, which are arranged in a "Z" shape, forming a three-tiered ladder for parent fish to lay eggs upstream. The ship lock is arranged on the right bank, the upper lock head is of water retaining gravity structure, and the working gate sinks. The irrigation canal is divided into left and right banks, and the water diversion flow is 1.5m3/s and 5m3/s respectively. The project was designed by Shanghai Survey and Design Institute, started by No.12 Hydropower Bureau of the Group Company, 1958, stopped by19651. Combined with the topographic characteristics of the reservoir area, the project adopts dike protection to reduce the flood and population migration in the reservoir area, and finds a feasible measure to solve the reservoir resettlement problem. During the operation of the power plant, the contradiction of small storage capacity, frequent floods and more abandoned water was reasonably solved by using the flood forecasting and dispatching method, and 74.2 million kWh of electricity was generated only in the three years from 1975 to 1977. At the same time, it also weakens the flood peak and reduces the loss of downstream flood.

work progress

During the period of 1956, Shanghai Hydropower Survey and Design Institute and Zhejiang Provincial Water Resources Department studied the hydropower resources of Qililong. 1958 The People's Committee of Zhejiang Province approved the Report on Preliminary Design Points of Qililong Hydropower Station compiled by Shanghai Hydropower Survey and Design Institute. In August of the same year, the power station officially started construction. 196 1 June, the second-stage cofferdam which was about to be completed was destroyed by flood, and the project was in trouble. The following spring, Zhejiang Provincial Committee decided to stop work and postpone construction. 1965 10 was approved by the State Planning Commission, the Construction Committee and the Ministry of Water Resources and Electric Power to resume construction. 1968 65438+February 13 Reservoir began to store water, and on February 25th, 65438, the first 57200 kW hydro-generator set began to generate electricity. April 5 1977 The last 60,000 kW hydro-generator set was installed and put into production. The total installed capacity of the whole plant reaches 297,200 kilowatts, including 57,200 kilowatts per unit/kloc-0 and 4 units with 60,000 kilowatts.

Fuchunjiang Lock Project is located on the right bank of Fuchunjiang Water Control Project in Tonglu County, Zhejiang Province, with the downstream about 1 10km and the upstream about 68km from Xin 'anjiang Hydropower Station. Built in the early 1960s, the standard is 100 tons, and the designed annual throughput is1000000 tons. Since the 1990s, due to various reasons, only when power plants generate electricity, the average number of times of crossing the lock is less than twice a day, resulting in a large number of ships waiting for crossing the lock upstream and downstream, and the waiting time is as long as ten days. The "bottleneck" of water transport in the middle and upper reaches of Qiantang River has become increasingly prominent. At present, the actual lock throughput of Fuchunjiang River is only 500,000-750,000 tons.

The expansion and reconstruction scheme of Fuchunjiang Shiplock is to build a 500-ton shiplock downstream of the original shiplock, with a basic size of 300×23×4.50 meters, and transform the original shiplock into an upstream approach channel. After the completion of the project, 500-ton ships can sail smoothly, and the annual cargo handling capacity of the lock will reach 25.6 million tons. A large number of water-suitable goods will be transported by water, and the materials in the middle and upper reaches and the middle and lower reaches will have convection. The estimated investment is about 873 million yuan, and the planned construction period is 28 months.
