The functions of hydroelectric power stations and thermal power stations are divided into two points during the wet season and the dry season.
1. During the flood season, the role of hydroelectric power stations is particularly important. Hydroelectric power plants use the kinetic energy of water flow to convert water flow into electrical energy via generators to provide electricity to people.
2. During the dry season, the electricity generation capacity of hydroelectric plants will decrease significantly. Due to the lack of water flow, thermal power plants will play an important role. Thermal power plants use coal, oil, natural gas and other fuels to produce thermal energy and convert thermal energy into electrical energy to provide electricity to people. The electricity production capacity of thermal power plants during periodsdry is stable.
What is the difference between choosing frequency-regulated power plants in the dry season and the wet season, and why?
The role of hydropower plants in the wet season is to support the base charge. According to relevant information, during the annual flood period, in order to fully play the role of daily adjustment of the installed capacity of hydropower plants, they no longer serve as the peak load of the system, and as the flow increases , the entire installed capacity gradually shifts from peak load to base load. The operation increases the electricity production of hydroelectric plants and reduces the operating costs of the system.
The large hydroelectric power station of the system during the dry season serves as the main frequency regulation facility, and the medium temperature and medium pressure condensing thermal power station hangsant the rainy season takes on the task of frequency regulation. According to relevant information, the power generation of hydropower plants during wet and dry periods is largely affected by factors such as weather conditions and water inflow of the year. The dry period is from January to April and December, the wet period is from January to December. From June to October, and the normal watering period is from May to November.
