Top 10 Questions for Hydroelectric Mechanic Interview

1. Explain the working principle of a hydroelectric power plant?

A hydroelectric power plant generates electricity from the energy of flowing water. The basic principle of operation is as follows:

• Water is diverted from a river or reservoir through a penstock, which is a large pipe.
• The water flows through the penstock and strikes the blades of a turbine, causing it to spin.
• The turbine is connected to a generator, which converts the mechanical energy of the turbine into electrical energy.
• The electrical energy is then sent out to the power grid.

2. What are the different types of hydroelectric turbines?

Impulse Turbines

• Pelton turbine
• Turgo turbine
• Cross-flow turbine

Reaction Turbines

• Francis turbine
• Kaplan turbine
• Propeller turbine

3. What are the factors that affect the efficiency of a hydroelectric power plant?

The efficiency of a hydroelectric power plant is affected by the following factors:

• The height of the water drop
• The volume of water flowing through the turbine
• The efficiency of the turbine
• The efficiency of the generator

4. What are the advantages and disadvantages of hydroelectric power?

Advantages
