Most of the water in the reservoir comes from surface water, and very little comes from groundwater from mountain springs. Surface water is nothing other than rainwater, which usually comes from rivers. So it's only fresh water. It can be used to water crops when the weather is dry. If the water from the reservoir is used as a source of drinking water, it must be protected after treatment.
The details are as follows:
1 Dams Most hydroelectric power plants rely on dams to retain water, forming a huge dam. reservoir.
2. When the water inlet opens the dam gate, the water will pass through a water channel called a tunnel under the action of gravity, which will guide the water flow to the turbine. Water pressure increases as it flows through a stream.
3. The flow of water from the hydraulic turbine impacts and rotates the enormoushe blades of the hydraulic turbine, and the hydraulic turbine is connected to the generator above by a transmission shaft. The most common turbine in hydroelectric power plants is the Francis turbine, which resembles a large plate with curved blades. According to data provided by the Foundation for Water and Energy Education (FWEE), the turbine can weigh up to 172 tons and rotate at a speed of 90 revolutions per minute.
4. When the generator's turbine blades rotate, a series of magnets in the generator also rotate together. Huge magnets spin through copper coils, moving electrons to create an alternating current.
5. The water present in the drive shaft reservoir that connects the turbine and the generator is considered stored energy. When the door is opened, the water flowing through the tunnel is converted into kinetic energy because it is in motion.
6. QuThe amount of electrical energy that can be generated depends on several factors, two of which are the size of the water flow and the height of the water. Water height refers to the distance between the water surface and the turbine blades. The higher the water height and water flow, the more electrical energy is generated. The water height generally depends on the storage capacity of the tank.
