6 FAQs about [Principle of the exhaust system of the hydro-turbine generator]

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.

What is the working principle of hydroelectric power generation?

The working principle of hydroelectric power generation is based on the fundamental principles of energy conservation and the law of conservation of mass . In a hydroelectric power plant, the water stored in a dam or a reservoir is allowed to flow under gravity through a penstock, which directs the water towards the turbine.

What is a governing system in a hydraulic turbine?

Governing system or governor is the main controller of the hydraulic turbine. The governor varies the water flow through the turbine to control its speed or power output. Generating units speed and system frequency may be adjusted by the governor. Governing system as per IEEE std. -75 includes following. GEN.

Which type of turbine is used in hydroelectric power plant?

Francis turbine is the most popular turbine compared to all other types of turbine used in the hydroelectric power plant as it has high efficiency and wide range of water head. This turbine is useful in the plant which has available water head between 130 to 2000 feet. A Francis turbine can work on both orientations; vertical as well as horizontal.

How does a governor control the flow through a turbine?

The governor varies the water flow through the turbine to control its speed or power output. Generating units speed and system frequency may be adjusted by the governor. Governing system as per IEEE std. -75 includes following. GEN. FLOW CONTROL WICKET GATES OR NEEDLE GEN. BREAKER Figure 6.1.: Governing System – Block Diagram (Typical)

How a hydropower turbine works?

According to the available water head and flow or volume of water, the hydropower turbine is selected. The hydropower turbines are classified into two types; As the name suggests, this turbine works on the principle of impulse. It uses the head of water and converts the pressure of water into kinetic energy with the help of nozzles.
