Can
Can. Because a 1000 watt water pump requires a 5 kW unit. Power is also divided into long-term (nominal) power and emergency power. Long-time power is the power with which the generator can work continuously for 12 hours, while standby power can only work for 1 hour during 12 hours of continuous operation.
A water storage power plant uses excess electrical energy to drive a water pump during the low electrical consumption period, pumping water from the lower reservoir to the upper reservoir for storage. During the peak electricity consumption period, the water stored in the upper reservoir is released to drive the generator to produce electricity, and the water returns to the lower reservoir.
In the process of using electricity to drive a water pumpwater in order to pump water, then release the water to produce electricity, due to the existence of friction and resistance, part of the energy must be converted into internal energy and lost. Therefore, ultimately, the electricity generated is less than the electricity consumed to pump the water. However, for hydroelectric power plants, the advantages far outweigh the disadvantages.
As for the question of the subject, it is not very clear. If it is a question of storing excess electrical energy, there is of course no explanation. If other energy is used to run the pump to pump water, and the water is then used to generate electricity, it is somewhat superfluous and the gain exceeds the loss. For example, if you use gasoline, it is better to directly use a gasoline engine to drive a generator to generate electricity, which is more direct, lessinconvenient and more energy efficient.
Seeing such a question, even if the person asking the question wants to work hard to find out the truth, this approach is still a stupid method of "taking off your pants and farting - useless".
My hometown is on a thousand-meter-high mountain. Because there is a sinkhole (we call it a hot tub), the whole mountain is empty, so of course there. There is no sinkhole, it is natural mountain spring water. Therefore, water for humans and livestock depends on several large artificially dug ponds. The ponds are filled with heavy rains in summer, but there are no draft problems. , in the event of a long drought in spring and summer next year, pond water cannot be connected, and drinking water for people and livestock will become a big problem. I remember once there was no water supply inns the whole mountain. People and animals went to the foot of the mountain to drink water, but they had to carry water on their shoulders and backs. there wasn't much water under the mountain. Ultimately, the county used fire trucks to supply water. To meet urgent needs.
The village leaders eventually decided to build a reservoir on the mountain and pump water from the bottom of the mountain to the top. To this end, men, women and children are at the top. mountain mobilized together, raised funds and volunteered to lift the power poles. We installed cables to provide electricity, built two pumping stations and dug a pumping well at the foot of the mountain. Finally, we used a three-stage pumping station. relay method for sending water to the first reservoir at the top of the mmountain, then used The action of gravity and the absence of power sends the water into the second reservoir (the second peak of the hill), and so on, through the mountains and ridges before reaching the pond.
Judging from reality, suppose the water is pumped up the mountain, and then the water from the mountain is used to produce electricity——
First, if we want to produce electricity continuously, we must have a constant flow of water. How big should the mountain reservoir be?
Second, the water in the reservoir is water without a source. Is it necessary to continually pump water up the mountain to solve the electricity problem? Rather than doing this, it is better to directly use the electricity or fuel used to pump water or generate electricity.
Third, assuming thathe cost of pumping water up the mountain is much higher than the cost of producing electricity, the gain exceeds the loss. Is there such a fool in the world? ?
In my opinion, there is no such designer or leader in the world, it's just for fun!
