The water-coal conversion coefficient is in fact the ratio of coal to water consumed by a power plant to emit the same electrical power. Therefore, the higher the permitted water consumption, the lower the water consumption. -coal conversion coefficient.
The output formula of hydropower is:
P=9.81ηHQ
P: Output unit: kW (kilowatt) Power transmitted from the end of the unit.
H: Unit of height: m (meter) The effective head acting on the turbine, which is equal to the difference between the reservoir water level and the downstream water level ( that is: gross head) minus the pressure loss of the water diversion part, the pressure loss △h, according to experience, it is generally 3% to 10% of Hg (gross height), and the smaller value is used for shorter water distribution channels.
Q: Flow unit: m3/s (cubic meter/second) indicated flow rate of the turbine in the hydroelectric power station.
η: The efficiency of the hydraulic generation unit, including turbine efficiency and generator efficiency η, is not only related to the turbine type and parameters and generator, but also changes with. changes in the operating conditions of the unit. This is not a fixed value.
Detailed information:
In the power system, power plants generally include thermal power plants, hydropower plants, nuclear power plants, wind farms, solar power plants, etc. In areas with low water resources, thermal power plants account for a larger proportion, while in areas with abundant water resources and a higher degree of developmentHowever, hydroelectric power stations represent a larger proportion. Wind farms and solar energy are new sources of energy. The main functions of hydroelectric power plants in the power system are:
(1) Providing electrical energy. This is the main task of hydroelectric power plants.
(2) Peak regulation. The main hydroelectric power station with regulating capacity acts as the main hydroelectric power station.
(3) FM. Large-scale units with tanks and strong adjustment capabilities are in charge. The frequency in China is 50 ± 0.2 Hz.
(4) Phase modulation. It has the ability to operate in phase modulation and can participate in balancing the reactive power of the system according to the requirements of the electrical network.
(5) As an emergency backup. Since the hydroelectric production unit has the characteristic of beingquickly started and connected to the grid for electricity generation, when a sudden accident occurs in the power system, there is an urgent need to replenish electricity and the units of the hydroelectric power station are often used. as emergency rescue units.

How many cubic meters of water does a 30 kilowatt hydroelectric power plant does it use per hour?

Maybe this can help you
Actual power generation The water consumption rate is 5.27 kg/
How many cubic meters of water are used per hour for the production of 30 kilowatt hydroelectric power? This question cannot be answered because there is no final straw. the need is greater. The less water, the smaller the drop and the more water used. If the goutof water is 100 meters, you can calculate it. The work done per 30 kilowatts per hour is equal to 30,000 watts times 3,600 seconds, which equals 1.08*10 8th joules of power. Water consumption is equal to 1.08*10 8th joules of power divided by (100 meters*9.8 meters per second). squared), or approximately 110,000. One kilogram is equivalent to 110 tonnes. 110 tonnes multiplied by 1 tonne per cubic meter equals 110 cubic meters. So for 30 kilowatts of hydroelectric power, the water level is 100 and the water consumption is about 110 cubic meters per hour. The above conclusion does not take into account energy loss.
