Question

describe the steps involved in converting hydro energy into electrical energy what fraction of total energy needs of our country is made to hydroelectricity​

Answer 1

Answer:

Dams are used in a range of applications, from river to medium-pressure and even high-pressure power stations in high mountain regions. Pump-storage power stations are being increasingly used to cover peaks in energy requirements. A number of gates are used to this purpose, and they have to be able to fulfill a wide range of tasks. This places many different demands on the hydraulic drives.

As enormous forces act on the construction, the drives have to be designed to with-stand high loads. For bottom outlet gates for example, pulling and pushing forces are required that can easily exceed several 1,000 kN.

At hydropower plants water flows through a pipe, or penstock, then pushes against and turns blades in a turbine to spin a generator to produce electricity. Run-of-the-river systems, where the force of the river's current applies pressure on a turbine.
