Best answer: What is needed to build a hydropower plant?

What materials are needed to produce hydropower?

The major components of a hydroelectric plant are a river, dam, turbine, generator, and power cables. All the components work together to generate electricity. A river that typically has a large drop in elevation at some point is ideal for a hydroelectric plant.

What infrastructure is needed for hydropower?

The infrastructure (basic building facilities and installations) required to develop hydroelectric energy is a dam, a hydroelectric power plant at the dam site to make power and the electrical grid for power distribution. Hydroelectric power generation does not create air, water, or thermal pollution.

How is hydro power plant constructed?

There are only six primary components required to construct a hydroelectric power plant. These are dam, pressure tunnel, surge tank, valve house, penstock, and powerhouse. The dam is an artificial concrete barrier constructed across the way of the river. The catchment area behind the dam creates a huge water reservoir.

What is needed for a hydroelectric power station to work?

Fast moving or falling water is the primary ingredient needed to create hydroelectric power. In most large scale constructions, the water is held back behind a dam and the force of the water being released is used to drive the blades of a turbine which in turn creates electricity that can be fed into the grid.

Which is the most suitable place to build a hydroelectric power plant?

Hydroelectric power plant is generally located near load centre. Explanation: Hydroelectric power plants are generally constructed in hilly areas. These power plants are quite away from the load centre. Explanation: In order to get sufficient head, hydroelectric power plants are constructed in hilly areas.

What are the two important components of a hydroelectric power plant?

A typical hydroelectric plant is a system with three parts: a power plant where the electricity is produced, a dam that can be opened or closed to control water flow, and a reservoir where water is stored. The water behind the dam flows through an intake and pushes against blades in a turbine, causing them to turn.

Which generator is used in hydro power plant?

Hydraulic turbines driven generators for hydro plant above 5 MW are salient pole synchronous alternating current machines. Large salient pole generators are relatively slow speed machines in the range 80-375 rpm with large number of rotor poles. These generators are specifically designed.

How does hydropower work step by step?

Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.

How is hydropower harnessed?

Flowing water turns the turbine, driving the generator and converting mechanical energy into electrical energy. Power is generated when water behind the dam flows through a pipe called a penstock. The water then turns a turbine that drives a generator. Hydropower plants generate electricity.

How do generators work?

Electric generators work on the principle of electromagnetic induction. A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet. … The magnetic field will interfere with the electrons in the conductor to induce a flow of electric current inside it.
