①The output is basically unchanged within 24 hours and is suitable to support the base load of the power system.
② The amount of electricity varies significantly each month of the year, and the amount of electricity in the dry season is significantly less than that in the flood season. Therefore, thermal or other power plants. the system must produce less energy during the flood season and more energy during the dry season, thereby reducing the utilization rate of the installed power supply capacity of the system.
③ There is a lot of abandoned water, and the water use coefficient of run-of-river hydropower plants is generally low. Where there is a regulating reservoir upstream, the water left behind will be reduced to varying degrees. .
④During the flood season, dam-type low-runoff hydroelectric power plant units do notoften fail to produce sufficient rated power (see hydropower plant design manager) or even fail to produce electricity due to rising water levels downstream. .
