The energy source for hydroelectric power is not only solar radiation. Hydropower is the use of water energy to generate electricity, and water energy mainly comes from the water cycle on earth. The water cycle refers to the continuous circulation of water between the ocean, land and atmosphere.
Solar radiation plays a key role in the water cycle, warming the Earth's surface, causing water to evaporate and rise into the atmosphere to form clouds and precipitation. This solar energy is absorbed by the surface and converted into thermal energy, causing the temperature in local areas to increase and the atmospheric pressure to drop, thus forming wind.
However, the hydraulic energy used by hydroelectric power plants is mainly converted from gravitational potential energy and cin energy.etiquette. When water from high places flows to low places due to gravity, gravitational potential energy is converted into kinetic energy. In a hydraulic turbine, this kinetic energy is converted into rotational mechanical energy, which in turn drives a generator to produce electrical energy.
Thus, although solar radiation is an important driver of the water cycle on Earth, it does not constitute a direct source of energy for hydroelectricity.
My analysis of the so-called safety of LZ should be 1. The danger caused by the explosion of the boiler or turbine, 2. The radiation risk in the substation. 3. Risks of chemical/wastewater release. 4. Risk of explosion between coal bunkers.
1. Boilers and steam turbines have very safe protective interlocks. When the vapor pressure or fluid flow rate exceeds thebalance limit of the boiler or steam turbine, it shuts down for protection, so the probability of explosion is very low.
2. There is certainly some ionizing radiation, but there is no need to worry about it if you travel 10 km.
3. As for sewage pollution, as long as the power plant actually discharges sewage, it cannot escape by circulating downstream, but the sewage treatment device of the power plant is generally necessary.
4. Coal bunkers have very comprehensive operating specifications, and usually this is not the case, but if an accident occurs it depends on the amount of coal stored. It depends on the explosion yield and radiation range, which are difficult to determine.
