Hybrid pumped storage project at both mouths of the Yalong River. The pumped-storage hybrid power plant is a hydroelectric power plant that has both pumped-storage and trickle-down power generation functions. The reservoir above the power station has sufficient natural runoff. It can not only use natural runoff to undertake tasks such as conventional and electricity generation. comprehensive utilization of water energy, but also increase peak load regulation, emergency relief and other tasks, such as the Yalong River Estuary Hybrid Pumped Storage Project , a hydroelectric power station with pumped storage and runoff power generation functions, which can not only use. natural runoff to undertake tasks such as electricity generation cconventional and full use of water energy, but also plays a role in It has functions such as peak shaving and valley filling, and emergency backup. It has the advantages of small losses due to tank flooding, without relocation. , low environmental impact, short construction period and better economics and competitiveness in the market. In a broad sense, the world refers to everything, anything and everything. Generally speaking, the world refers to the land on which human beings live.
Water cycle electricity generation is not feasible
Should a hydroelectric power plant be built in the world's driest desert? real! This hydroelectric power plant project in the desert has successfully passed the environmental impact assessment. The initial plan was to begin construction in the second half of 2016 and complete the hy plantdroelectric in three and a half years.
But where does the water come from? Chile proposed a bold idea: use solar power to pump seawater to a mountaintop reservoir, then let the seawater flow out to generate electricity.
The British "Daily Mail" reported on the 11th, citing people familiar with the matter, that the Chilean energy company Valhalla plans to build a hydroelectric power station with an installed capacity of 300 megawatts in the desert of Atacama. the project is expected to cost $400 million.
The Atacama Desert is the driest desert in the world outside of the Arctic and Antarctica, with an average annual rainfall of just 1.5 centimeters. However, the desert has a unique geographical location, bordering the Pacific Ocean all the way to the south. in the west and in the Andes in the east, Chilean designers have found a "new idea".
According to the vision of Valhalla, theSolar power can be used to pump water from the Pacific Ocean to two reservoirs high in the Andes, then allow the seawater to flow down through hydroelectric plants to produce electricity .
Experts said the aim of the move is to overcome a major drawback of renewable energy sources such as solar and wind power, namely instability.
Since the amount of sunshine and wind strength change at any time, it is difficult to ensure stable electricity production from solar and wind energy. However, many peaks in the Andes are over 6,000 meters above sea level. stable electricity production can be ensured thanks to differences in water potential.
Electricity generation by water cycle is not feasible due to current technology and limited terrain factors, it does notThere is therefore no way to implement it on a large scale. To generate electricity by circulating water, build an appropriately sized sealed water tank in a high location and connect it to a water pipe that can supply water to the generator on the ground. Push the generator turbine to drive the generator to produce electricity. The generated water is stored in a water tank and consumes very little electricity thanks to the principle of atmospheric pressure. Let the water pump pump water to a water tank located several feet higher than the generator water level. or connect it directly to the water replenishment pipe of the sealed water tank at a high location to return water to the water tank. This cycle repeats, forming a circulating water energy production.
