Separate combined powerhouse system for tubular hydropower station

Abstract

The invention relates to the technical field of hydropower stations, specifically to a separation and combination type plant system of a through-flow hydropower station. The system adopts the following method steps: (1) a traditional through-flow set and such parts as a generator pier, an electric room, an accessory equipment room and a booster station are partitioned; (2) the through-flow set and the generator pier are placed in a riverway, and a water retaining gate dam is arranged above the through-flow set and the generator pier; and (3) in a power generation water head range, the water retaining gate dam blocks water, and the upper part of a concrete pier of the set is exposed out of the water surface. The system uses the characteristic of underwater operation of a through-flow water turbine generator set to divide a traditional main plant, can combine the set pier, the electric room, the accessory equipment room, the booster station and the like which can be in and out of water, enables all parts to be independent from each other and flexibly arranged, can improve the flood discharging capacity of the through-flow hydropower station, reduces the construction cost, shortens the construction period, and improves the plant stability.

Description

【Technical field】 [0001] The invention relates to the technical field of hydropower stations, in particular to a separated and combined powerhouse system of a tubular hydropower station. 【Background technique】 [0002] Today's energy situation is tense. Non-renewable resources such as petroleum and coal are becoming increasingly depleted, and environmental issues are increasingly valued by everyone. The development of clean and renewable energy has long become an international topic. Clean and renewable energy such as hydropower, wind power, and solar power is developing rapidly. Among renewable energy sources, hydropower has the best economy and more mature technology. my country is rich in water resources, the most in the world, but the development capacity and degree of water resources are relatively backward. According to statistics in 2015, the degree of development of my country's water resources is 43%, and there is still a lot of room for development. As far as sma...

Problems solved by technology

To meet these requirements, hydraulic structures are expensive

[0005] (3) In order to meet the water retaining requirements of a higher flood control level, the main building of the power station is increased, and the buoyancy force is large and the stability is poor

[0006] (4) In order to ensure the stability of the factory building, the construction scheme of "multiple machines and one seam" is generally adopted, which increases the difficulty of construction of large-volume concrete

[0007] The above-mentioned points have caused the problems of large investment and long construction period of the tubular hydropower station
