1) In a tidal bay or estuary, you can watch the rise and fall of sea or river water twice a day. The one in the morning is called a tide and the one in the evening is called a tidal wave. . This phenomenon is mainly caused by the tidal force of the Moon and the Sun and the effect of the Earth's rotation. Tide is a renewable energy source with huge reserves, inexhaustible and inexhaustible, which does not require mining or transportation, and is clean and non-polluting. The construction of tidal power plants does not require resettlement, does not flood land, and does not pose any environmental pollution problems. It can also be combined with tidal power generation to develop comprehensive utilization projects such as rehabilitation, aquaculture and marine chemical industry. 2) The principle of tidal power generation is similar to that of hydroelectric power generationordinary eu. Upon leaving the reservoir, seawater is stored in the reservoir at high tide and stored as potential energy. Then the sea water is released at low tide, using. the difference between high and low tide levels to favor the water turbine turns and drives the generator to produce electricity. The difference is that sea water is different from river water. The height of the accumulated seawater is not great, but the flow is large and intermittent. Therefore, the structure of the tidal power generation turbine must be adapted to the characteristics of low head and large flow. . 3) Tidal power generation is a type of hydroelectricity generation. Build dams, gates and workshops in qualified bays or inlets to form a reservoir. A certain tidal difference (i.e. working height) forms between the water levelof the reservoir and the tide level of the outer sea, which can cause the hydroelectric generator to operate. produce electricity. 4) Technology related to tidal power generation has advanced extremely rapidly. Various mechanical equipment has been developed to convert tidal energy into mechanical energy, such as propeller turbines, axial flow turbines, open circulation turbines, etc. Japan has even started to do it. use artificial satellites to provide current information. The use of tidal power generation is more and more mature and has entered the practical stage.
The waters of the Yangtze River estuary region are not safe for swimming due to busy waterways and turbulent currents. Swimming in the Yangtze River estuary is not recommended. Tidal power generation is a method of usingion of renewable energy that can efficiently use tidal generated energy and is a relatively environmentally friendly method of energy production. However, tidal power generation requires certain technologies and facilities, and scientific and reasonable site selection and construction are necessary to achieve sustainable power generation. Therefore, if tidal power generation is to be developed in the Yangtze River estuary region, it is necessary to carefully evaluate factors such as geographic environment, hydrology and meteorology, and formulate a scientific and reasonable construction plan.
The Yangtze River estuary region is very rich in tidal power resources and is one of the potential sites for tidal power generation. Tidal characteristics in the Fl estuary areaYangtze river are large tidal amplitude and long tidal cycle, which is suitable for the construction of large-scale tidal power generation facilities. In addition, the tidal currents in the Yangtze River estuary region are relatively turbulent, which can increase the power generation efficiency of tidal generator units. At the same time, the Yangtze River estuary region is also very rich in water resources, which can be combined with tidal power generation to improve the utilization efficiency of the entire energy resources of the water.
