Introduction If you use a pump to pump water from the bottom of the mountain to the top of the mountain, install it to generate electricity. Is it correct? Water storage power plants use excess electricity to operate water pumps to pump water from the lower reservoir

If you use a pump to pump water from the bottom of the mountain to the top of the mountain, install

A water storage power plant uses excess electrical energy to drive a water pump during the low power 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 pump to pump water and then releasing 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, less troublesome 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 whirlpool), the whole mountain is empty, so wellsure 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 in the entire 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 finally decided to build a reservoir sur 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 to send water to the first reservoir at the top of the mountain, then used The action of gravity and no power sends the water to the second reservoir (the second top 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, assume that the cost of pumping water upstream is much higher than the cost of producing electricity. Well, 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!
