Due to the force of the tides, sea water continually rises and falls. When the tide rises, a large amount of seawater surges forward, with great kinetic energy; at the same time, the water level gradually rises and the kinetic energy is converted into potential energy; At low tide, sea water recedes, the water level gradually drops, and potential energy is converted into kinetic energy. The kinetic energy and potential energy possessed by moving seawater are collectively called tidal energy. From an energy perspective, tidal power generation is a way of producing electricity by using the potential and kinetic energy of seawater and converting it into electrical energy via a hydroelectric generator; like rivers and lakes to flow to low places. The potential energy it contains is converted into kinetic energy of the turbinehydraulic, then the hydraulic turbine is used as the main engine to drive the generator to generate electric power. The above two methods of generating energy are simple. It is not difficult to see that tidal power generation has more energy conversion than ordinary hydropower generation. Their essence is the same. If we want to make a difference, tidal power generation is more environmentally friendly than ordinary hydropower generation, and the energy conversion is greater. Additionally, tidal power generation has time limits, but the regional problems of ordinary hydropower generation do not; production methods are suitable Regional tidal power generation will be smaller than ordinary hydropower generation, or both methods are suitable for different regions, and tidal power generation will be rrelatively more difficult to achieve.
Tidal energy can be generated four times a day.
Detailed explanation:
The first generation of electricity occurs during the high tide phase of the tide. When the water begins to rise, the tidal power plant opens the gates or starts the turbines, using the energy of the rising tide to convert the water flow into electricity. This process usually occurs early in the morning or early in the morning. The second generation occurs at high tide after high tide. Tidal power plants continue to harness the energy of flowing water to produce electricity. This period usually occurs in the morning or at midday.
The third generation of electricity occurs during the ebb phase of the tide. When the water begins to recede, tidal power plants again use the energy from the water flow to convert it into electricity. This period occursusually in the afternoon or evening.
The fourth generation occurs one low tide after another low tide. When the tide reaches its lowest level, the tidal power plant continues to use the energy of the water flow to produce electricity one last time. This period usually occurs in the evening or night.
The concept of tidal power generation:
Tidal power generation is a renewable energy technology that uses the rise and fall of ocean tides to generate electricity. 'electrical energy. Compared to solar and wind energy, tidal energy is more stable and predictable.
Advantages of tidal power generation:
1 Predictability and stability
Compared to unstable energy sources such as solar energy and wind energy. As a form of energy, tidal energy offers greater predictability and stability. The rise and fall ofTides are determined based on the gravity of celestial bodies and can be calculated and predicted in advance, making network planning and energy management more reliable and efficient.
2. High energy density
Tidal power plants can use the enormous energy of water flow brought by tidal fluctuations to produce higher energy density. Also compared to photovoltaic solar panels or wind turbines, tidal power can produce more electricity in a relatively small area.
3. Environmentally friendly and clean
Tidal power generation is a zero-emission form of energy that does not produce greenhouse gases or other pollutants. It has a relatively low impact on the environment and does not cause problems such as air pollution, soil damage or water consumption.
4. Long life and durabilityté
Tidal power generation equipment generally has a long lifespan and can operate for decades or more. The rise and fall of tides is a long-lasting natural phenomenon that is not affected by human factors, so tidal power generation can provide a reliable long-term energy supply.
5. Do not occupy large areas of land
Compared to forms of energy such as solar power and wind power which require large areas of land, tidal power plants can generally be built in areas such as oceans or estuaries and do not require large areas of land. This will require a lot of land resources.
