There are three broad categories of energy production principles:
1. Photovoltaic power generation uses the photovoltaic effect at the semiconductor interface to directly convert light energy into electricity. energy.
2. Hydroelectric production, the potential energy of water is converted into mechanical energy and then into electrical energy.
The basic principle of hydroelectricity is to use the difference in water level to produce electricity with a hydroelectric generator, that is, the potential energy of the water is converted into mechanical energy of the water wheel, and then into mechanical energy. mechanical energy is used to drive the generator to obtain electricity. Scientists take advantage of the natural conditions of water level difference, effectively use fluid engineering and mechanical physics and carefully combine them to achieveachieve the highest power generation capacity, so that people can use cheap and pollution-free electricity.
3. Thermal energy production, thermal energy is converted into mechanical energy, and mechanical energy is converted into electrical energy.
Thermal power generation generally refers to the use of thermal energy generated when fuels such as oil, coal and natural gas are burned to heat water, transforming the water into water vapor at high temperature and high pressure, and then use the water vapor to drive a generator to produce electricity. The general name of the method. Power plants that use coal, oil, or natural gas as fuel are collectively called thermal power plants.
The basic working principle of the generator is based on the law of electromagnetic induction and the law ofelectromagnetic force. Suitable magnetic and conductive materials are used to form magnetic circuits and circuits that conduct electromagnetic induction between them. generate electromagnetic energy and realize energy conversion.
