Description

Technical Field

[0001] The invention belongs to the technical field of hydropower generation, and in particular relates to a reaction-type turbine stilling pool. Background Art

[0002] Hydroelectricity, also known as hydroelectric power generation, is a process of converting energy by using the head difference in water bodies (i.e., the elevation difference or drop of the water body) to do work, specifically converting the water energy contained in water bodies such as rivers, lakes or oceans into electrical energy. The following is a detailed analysis of hydroelectricity: The basic principle of hydroelectricity is to use the energy released by water flowing from high places to low places. This energy is called water energy. When the water passes through the turbine, it will drive the turbine to rotate, and then drive the generator to generate electricity, thereby converting the potential energy of the water into electrical energy. The main equipment of a hydroelectric power station includes turbines, generators, speed governors, excitation systems, control systems, etc. Among them, the turbine is the key equipment for converting water energy into mechanical energy, and the generator is the core equipment for converting mechanical energy into electrical energy.

[0003] In water conservancy and hydropower discharge structures, the stilling pool is a device that causes the downstream water flow to generate a hydraulic jump downstream of the discharge structure, converting the kinetic energy of the water into other forms of energy for energy dissipation.
