How to calculate the daily electricity production of a hydroelectric plant?

First calculate: the work done by the water on the generator each day

Work = flow rate (volume of water flowing in a day) * water pressure on the blades (according to calculation, 490000Pa) * time (one day)

Calculate the amount of energy that the generator can use (the amount of electricity produced today):

Work of generator = work of water * efficiency of generator

The formula for the power of a hydroelectric plant: N=9.81QHη

In the formula, N is the power of the hydroelectric plant (kW) Q is the reference flow (m3); /s); H is the net water height (m) (see height of the hydroelectric power station); eta is the total efficiency of the hydrogenerator unit, and its value is 0.70 to 0.90.

The annual electricity production of hydroelectric plants is not calculated based on the installed capacity, but based on the volume of water. The amount of water used by the tank forhe electricity production over the course of a year can be recalculated to calculate the annual electricity production. The installed capacity of hydroelectric plants is calculated on the basis of the average maximum flow.

Detailed information:

The electrical power of a period is equal to the power average of the period multiplied by the number of hours of the period.

When the proportion of hydropower in the power system is large and there is a large amount of seasonal energy, the available power of the hydropower plant may not necessarily be fully utilized by the system electrical, which leads to water loss. power. From this, the available power of the hydroelectric plant can be calculated, after deducting the electricity consumption of the hydroelectric plant and the energy transmission and transformation losses before theput online, this is the effective power supply to the hydroelectric plant. The electricity produced by hydropower plants provides an important basis for calculating the benefits of electricity production from hydropower plants.
