Peak electricity production was more than 400 million kilowatt hours per day when water volume was high this summer. The converted power is approximately 17 million kilowatts. 24 or 25 generators have been started these days. , but the gap is larger. The daily power is estimated at about 4 million kilowatts and the overflow of each generator is about 870 cubic meters per second, according to the flow and waterfall of the Three Gorges provided by the Three Gorges Society website . ://www.ctgpc.com.cn/, the gap is the total gap between Gezhouba and the Three Gorges. You can roughly calculate the power and electricity generation.
How much electricity can the Three Gorges hydropower produce. Does the station generate in a day?
To produce electricity under a 30 meter high dam, one kilowatt hour of electricity requires 6.5 cubic meters of water. According to the rquery for relevant public information: atmospheric pressure is 0.8 MPa, water height is 80 meters, 6.5 cubic meters of water can generate one kilowatt hour of electricity. When 40 cubic meters of water are used, 6.15 kilowatt hours of electricity (take). 6 degrees), 2 kW can be generated for 3 hours, provided the air pressure is kept constant.
How much water does a hydroelectric generator use to produce electricity?
The total installed capacity of the Three Gorges Hydroelectric Power Station is 22.4 million kilowatts.
In other words, the Three Gorges hydroelectric power station can theoretically produce 022.4 million kWh of electricity per hour (equivalent to 537.6 million kWh/day).
But in reality, this objective is far from being achieved. It depends on water flow conditions, unit condition, start-up time...and other factors.
According toOfficial data released by China Three Gorges Corporation, the multi-year average electricity output of the Three Gorges Power Station is 88.2 billion kWh. Based on this calculation, the average daily electricity production is approximately 242. million kWh.
The air pressure is 0.8 MPa, which is equivalent to a water depth of 80 meters. Generally, it can be estimated that 6.5 cubic meters of water can generate one kilowatt hour of electricity. cubic meters of water are consumed, 6.15 kilowatt hours of electricity can be generated (take 6 kilowatt hours), or 2KW can be sent for 3 hours. The principle is that the atmospheric pressure remains constant. In fact, the electricity you use for pumping must be much higher than the electricity produced by the generator, can you believe it? .
