Runoff size, runoff size and sand content size.
1. The amount of runoff: The amount of runoff is an important factor affecting the amount of energy produced. The greater the amount of runoff, the greater the amount of energy generated.
2. The magnitude of runoff: Rivers with large seasonal changes in runoff exhibit large differences in power generation between wet and dry periods and have low seasonal adjustment capabilities.
3. The size of the sand content: The size of the sand content affects the flow rate and impact force of the water flow, which in turn affects the efficiency of power generation.
1. Relieve the tense power supply situation.
2. During periods of flooding, water storage will reduce water losses downstream and reduce rivers.flood scars in the middle and lower reaches of the Yangtze River.
3. The increase in power generation of downstream power plants during the normal dry period has a significant compensation effect on downstream cascading power plants such as Yalong River, Jinsha River, Baihetan, Wudongde and the main river three from the Yangtze River. Gorges and Gezhouba Save 13.3 million tons of raw coal and reduce 21.3 million tons of carbon dioxide emissions.
