Hello everyone, let me introduce about myself first. I’m Quynh and I’m 13 years old. I study in class 7C at Phu Cu secondary school. Today, I’m very happy to talk about Hydropower plant.
As you know, electricity can be generated in many different ways, such as water, wind or coal, but mosly water. You can see many hydropower plants anywhere. In our country, there’re 3 famous hydropower plants : Hoa Binh hydropower plant, Son La hydropower plant and Lai Chau hydropower plant. So,what does hydropower mean? It means human uses the water to produce electricity in the place and that place is hydropower plant. The hydropower plant is mainly located near the rivers and it mainly uses the water from rivers to produce electricity.
So, what is the importance of the hydropower plant?
First, it cantains a huge amount of water. In the water reservoir, a constant volume of water flows days and nights to serve the generation of electricity. Secondly, the biggest benefit of hydropower plant is its limited fuel cost. Hydropower plants are not subject to price hikes of fossil fuels such as oil, natural gas or coal, and do not need to import fuel. Hydropower plants also have longer lifespans than thermal power plants, with some of the hydroelectric plants in operation today that were built 50 to 100 years ago. Labor costs are also low because these factories are highly automated and have few people working on site during normal operation. The reservoirs built together with hydroelectric plants are often great relaxation spots for water sports, and become tourist attactions. Mulifunctional dams, built fo irrigation, flood control or enetertainment, could add a low – cost hydroelectric power plant, providing a useful source of revenue for dam operation. In the practice, the use of stored water is sometimes quite complicated because irrigation requiements may occour that do not coincide with the time when electricity requirements peak. Droughts can cause problems, because water replenishment levels cannot keep up with required levels. If the munimum level of replenishment is not sufficient, it can result in reduced efficiency and it is not economical to install a small turbine for that flow.
That is all my knowledge about hydropower plant. If you have some news, you additional to me. Thank you for your listening!
