The reason why Lianghekou Hydropower Station increases the power generation of downstream hydropower

1. Relieve the tense power supply situation.

2. During flood periods, water storage will reduce water abandonment downstream and reduce flood risks 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.

Hydroelectric exploitation is more limited by incoming water and the installed capacity of power plants is limited.

During the dry season, the power plant can use surplus units and limited water volume for point regulatione, and the hydroelectric unit adjusts the peak load. The peak performance is very good, which can reduce the efficiency loss of thermal power peak regulation and achieve the highest overall efficiency of the power system.

During the humid period. In season, the power plant has plenty of water. In order to avoid losses due to water abandonment, it is necessary to maximize the use of electricity generation by using incoming water as much as possible. Currently there is no excess peak. It is necessary to use thermal energy or pumped storage for peaking. In this way, even if the peak efficiency of thermal power is lost, the cheap hydropower is used to generate electricity and the overall efficiency of the power system is improved. can still be improved
