The simplest method is to calculate based on your electricity meter, record the amount of electricity produced during a certain period of time, then divide it by the time, which is the power of your generator, for example if electricity is produced. The meter you record for one hour is 100 degrees, that is, 100 kilowatt hours, divided by one hour, the generator power is 100 kilowatts. I don't know which aspect you are talking about between the theoretical value and the real value. If the above calculation method is used, in addition to the influence of power factor and multiple reactive power, it is also more accurate. If we talk about the generator power calculated based on the head flow, then it is difficult to determine the actual difference in power generation which may be affected by the manufacturing process and construction of the flow channel ins the spiral chamber of the power plant.
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 to official 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 height 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? .
