What are the factors necessary for the installation of hydroelectric power plant?

The rock structure should be stable and there should be least occurrence of the earthquakes in the region. The rock structure should not allow the seepage of water and it should be waterproof. 3) Sufficient water is available: The flow of water where dam is constructed should be sufficient enough to fill the dam.

What is the most important consideration when constructing a hydroelectric power plant?

The choice of the appropriate dam type and construction method must be influenced by the unique conditions of the dam site, and stability of the site is a key consideration.

What is the basic requirements of hydroelectric power station?

Availability of water, large catchment area and rocky land are primary requirements for site selection of hydroelectric power plant. Explanation: Potential energy of large quantity of stored water is used by hydroelectric power plant to generate electrical energy.

Which of the following factors affect the production of electricity in a hydropower plant?

Among physical factors two prime factors are quantity of water and degree of slope. The greater the quantity of water available, and steeper or longer the slope, the greater is the energy generated.

How are hydroelectric dams built?

Hydroelectric power is produced as water passes through a dam, and into a river below. … Once a dam is built, an artificial man-made lake is created behind the dam. Electricity is produced by a device called a turbine. Turbines contain metal coils surrounded by magnets.

What are the factors affecting the location of hydroelectric power station?

Factors Affecting a Selection Site for a Hydroelectric Station

  • Raw Materials. The materials used in the construction of dams determine whether it will last for long or effectively serve its purpose. …
  • River Path. …
  • Geological Structure. …
  • Sufficient Water.

What are the components of hydroelectric power plant?

What are the major components of a Hydroelectric Power Plant?

  • Head race tunnels/channels.
  • Surge shaft/surge chambers.
  • Pressure shaft/Penstock.
  • Underground and surface power house.
  • Tailrace channel or tailrace tunnel.

How are the hydroelectric turbine selected while constructing a hydroelectric power plant?

Generally, the construction of turbines is the same. … The type of turbine selected for any given hydropower project is based on the height and speed of the incoming water – known as the hydraulic head – and the volume of water that flows known as the hydroelectric discharge.

How is hydroelectric energy converted into electricity?

Hydroelectric power is produced with moving water

IMPORTANT:  How has solar energy changed the world?

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.

What conditions are necessary for the generation of hydroelectric power in India?

Perennial flow of water is necessary for generating hydro-electricity. 3. Suitable climate : In very cold regions the water of river freezes and generation of electricity stops. But the climate of India is suitable for generation of hydro-electricity.

How does hydroelectric dams affect the environment?

Hydropower does not pollute the water or the air. However, hydropower facilities can have large environmental impacts by changing the environment and affecting land use, homes, and natural habitats in the dam area. … Methane, a strong greenhouse gas, may also form in some reservoirs and be emitted to the atmosphere.

What is a hydroelectric power plant?

Hydropower plants capture the energy of falling water to generate electricity. … Then a generator converts the mechanical energy from the turbine into electrical energy. Hydroplants range in size from “micro-hydros” that power only a few homes to giant dams like Hoover Dam that provide electricity for millions of people.

Which method is used to produce electricity in a hydroelectric power plant Mcq?

Of given methods, which method is used to produce electricity in a hydroelectric power plant: Heat energy of water converted to mechanical energy. Potential energy of water converted to mechanical energy. Ionization of water to obtain chemical energy.

Who invented hydroelectric power?

Hydropower became an electricity source in the late 19th century, a few decades after British-American engineer James Francis developed the first modern water turbine. In 1882, the world’s first hydroelectric power plant began operating in the United States along the Fox River in Appleton, Wisconsin.
