Frequent question: On which generation of hydropower depends Mcq?

On what does generation of hydropower depends?

The hydro power principles

Power generation from water depends upon a combination of head and flow. Both must be available to produce electricity. Water is diverted from a stream into a pipeline, where it is directed downhill and then through the turbine (flow).

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.

What is hydroelectricity generation?

hydroelectric power, also called hydropower, electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy. … The turbines in turn drive generators, which convert the turbines’ mechanical energy into electricity.

On which parameter the output of hydroelectric power plant depends Mcq?

discharge, system efficiency. The power developed by a hydro power plant depends upon the discharge and head and is directly proportional to their product and also proportional the system efficiency. The electrical power P is given as P = WQHð × 9.81 × 103 KW.

IT\'S FUNNING:  How does the Clean Air Act affect power plants?

What is the contribution of hydroelectricity in the total generation of electricity?

Hydropower is a very important source of renewable electricity, with a share of 16%–17% of the total world electricity generation. Hydropower is by far the largest source of renewable electricity, in 2016 with more than twice the contribution from all other renewables combined.

What is the basic requirements of hydroelectric power station MCQS?

Availability of water, large catchment area and rocky land are primary requirements for site selection of hydroelectric power plant.

What are the two main types of hydro power plants?

There are three types of hydropower facilities: impoundment, diversion, and pumped storage. Some hydropower plants use dams and some do not.

What are the types of hydro generators?

Learn More. There are two main types of hydropower turbines: reaction and impulse. The type of hydropower turbine selected for a project is based on the height of standing water—referred to as “head”—and the flow, or volume of water over time, at the site.

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

By running dynamo the potential energy of water.

Which is the first hydroelectric project in India?

Sidrapong Hydroelectric Power Station ( a.k.a. Sidrapong Hydel Power Station), located at the foothills of Arya Tea Estate 12 km (7.5 mi) from Darjeeling town, is the oldest hydel power station or hydroelectric power plant in India.

What are advantages of hydroelectric power generation?

Hydropower provides benefits beyond electricity generation by providing flood control, irrigation support, and clean drinking water. Hydropower is affordable. Hydropower provides low-cost electricity and durability over time compared to other sources of energy.

IT\'S FUNNING:  Frequent question: How does energy transformation happen?

What is hydroelectricity for 4th class?

Hydroelectricity is the term referring to the production of electrical power through the use of the gravitational force of falling or flowing water.
