Description
Technical Field
The invention relates to the technical field of hydroelectric power generation methods, in particular to a method for secondary power generation by utilizing the gravity of water.
Background
Hydroelectric generation, and research on engineering construction and production operation and other technical and economic problems of converting water energy into electric energy. The water energy utilized by hydroelectric power generation is mainly potential energy stored in a water body. To convert water energy into electric energy, different types of hydropower stations need to be built.
The hydroelectric generation utilizes water with potential energy in river, lake and the like located at high positions to low positions to convert the potential energy contained in the water into the kinetic energy of a water turbine. According to the law of conservation of mechanical energy, in hydroelectric power generation, the larger the water head difference is, the larger the kinetic energy obtained by the water turbine is, and the higher the generated electric energy is. There are a number of forms of hydroelectric generation, of which conventional Cheng Shuili generation, pumped storage hydroelectric generation and tidal power generation are more common.
The hydraulic power generation of the inertia routine is to build a reservoir at a proper place where a river is searched, and the water diversion tunnel is used for diversion and impacting the water turbine to rotate so as to synchronously drive the generator to generate power, and the voltage is increased through the transformer and is linked to the transmission tower to be transmitted to various places for use. And the power generation water after the power generation is finished is discharged to a downstream river through a tail waterway and is continuously supplied for downstream folklore or power generation.
Pumped storage hydroelectric generation is a way of indirectly storing electric energy, which is generated for solving the contradiction between supply and demand between peaks and valleys of a power grid. The water pump is driven by the surplus electric power in the lower half of the night, water is pumped from the lower warehouse to the upper warehouse to be stored, and then the water is discharged for power generation in the daytime or in the upper half of the day and flows into the lower warehouse. Although there is some energy loss in the whole process, pumped storage power stations are one of the technical means for efficient and economical energy storage today.
Ocean tidal power generation is similar to extraction-storage type hydroelectric power generation. Tidal energy is energy generated by periodic sea water fluctuation under the action of gravity such as moon and sun, and comprises periodic vertical lifting of sea surface and periodic horizontal flow of sea water, wherein the vertical lifting part is potential energy of tide, and is called tidal energy. The current mature tidal power generation mode is reservoir type, namely, a dam, a gate and a factory building are built at the estuary of a bay or a sea tide, the estuary of the bay or the sea tide is isolated from the open sea to enclose a water reservoir, the reservoir is filled with water when the tide is risen, and the gate is opened when a certain water level difference exists after the tide falls, so that the water turbine set is driven to generate power.
The conventional hydroelectric power station can only perform single-time utilization power generation on stored water, if water needs to be reused, a power station needs to be built at the downstream of the power station, and a power station needs to be additionally built, so that a great deal of manpower, material resources and financial resources are consumed, a great deal of time is consumed, and the normal use of an upstream power station is greatly influenced in the process of building a dam.
For this purpose, a method of secondary power generation using the gravity of water is proposed.
