三峡电站水轮机性能和结构特点评析（The performance and structure of the water turbine of the three gorges hydropower station are analyzed）

三峡电站水轮机性能和结构特点评析（The performance and structure of the water turbine of the three gorges hydropower station are analyzed） Analysis of the performance and structure of water turbine in three gorges hydropower station Huang yuanfang li literature The three gorges project is a huge investment, and the only way to recycle it is to generate electricity from the three gorges hydropower station. As one of the core equipment of the power plant, the water turbine is the key to the performance of the project. The three gorges water turbine has a rated output of 710MW and the wheel diameter reaches 10m. It is the largest and largest mixed flow turbine in the world. The structural design and manufacturing process of large-sized mixed-flow hydraulic turbine is also a technical challenge. Based on the three gorges hydraulic turbine model test, this paper introduces and analyzes the structural features and characteristics of the main components of the three gorges water turbine. Keywords: three gorges project hydraulic turbine performance structure The three gorges hydropower station has a total of 26 hydropower stations with a rated capacity of 700MW. The 14 units of the left bank power station signed the contract in September 1999 through international public bidding and bidding. 14 units rated head of 80.6 m, the rated output of 710 mw mixed-flow turbine respectively by two group is responsible for the supply, VGS joint (German Voith GEHydro, Canada, Germany Soemems) received 6 sets of contract, French AISTOM group obtained 8 sets of contract. The contract two group adopt their own hydraulic design, VGS using the hydraulic model of joint development, AISTOM were asked to use the Norwegian KVAERENER energy company (hereinafter referred to as KEN) developed by hydraulic model. The most common thing the two models have in common is that the rotor blades are x-shaped blades. 1. Characteristics of water turbine performance of three gorges The design and manufacturing contract of the
