Hydro storage power generation is a large-scale device that stores off-peak electricity in the potential energy of water and then uses it to generate electricity during off-peak hours. peak electricity consumption.
Water storage for power generation involves using water pumps to pump water to high locations during low power consumption in certain areas where energy consumption is low, then drain water during peak energy consumption. . Principle of electricity generation As above to compensate for power grid failures due to excessive load during peak energy consumption.
Power generation refers to the use of power generation devices to convert water energy, thermal energy from fossil fuels (coal, oil, natural gas, etc.), energynuclear energy, solar energy, wind energy, geothermal energy. , ocean energy, etc. in electricity. Nowadays, fossil fuels are mainly used for electricity generation, but there are not many fossil resources and they are gradually running out. Human beings have gradually used more renewable energies (hydraulic energy, solar energy). energy, wind energy, geothermal energy, marine energy, etc.) to produce electricity.
The mass of water in 36O cubic meters of water is m=pV=(1000kg/m^3)*360m^3=3.6*10^5 kg
Pump 36O cubic meters of water The minimum work required to reach a height of 5 meters
=mgh=(3.5*10^5 kg)*(10N/kg)*5m=1.8*10^ 7 J
Power P=work/time=(1.75*10^7 J)/0.5h=(1.8*10^7 J)/1800s=10000W=10kW
Considering the mechanical efficiency problem, the required power is more than 10 kW
