FAQS about The function of the wind shield of the hydro-turbine generator

How do hydro turbines work?

Hydro turbines are devices used in hydroelectric generation plants that transfer the energy from moving water to a rotating shaft to generate electricity. These turbines rotate or spin as a response to water being introduced to their blades. These turbines are essential in the area of hydropower - the process of generating power from water.

Why is a turbine important in a hydropower plant?

The turbine is considered to be the heart of any hydropower plant since it converts the power of water into rotation of a shaft which, through a generator, is capable of producing electricity. Since the key lies in the efficient conversion of the power of water into rotation, the proper selection and operation of the turbine is very important.

How does a hydroelectric generator work?

Employing the principle of electromagnetic induction, the electric generator transforms the mechanical energy of a rotating turbine shaft into electric energy. Due to the lower rotation frequency of water turbines, generators in hydroelectric power plants are much larger than generators of the same output in thermal power plants.
