Which type of hydro power plant can be with or without Pondage?

Run-of-river hydroelectricity (ROR) or run-of-the-river hydroelectricity is a type of hydroelectric generation plant whereby little or no water storage is provided.

What type of hydropower plant can be with or without Pondage?

Which type of hydro power plant can be with or without pondage? Explanation: Run-off river power plants can be with or without pondage. A runoff river plant without pondage has no control over river flow and uses water as it comes.

What is Pondage in a hydropower station?

Pondage refers to the comparably small water storage behind the weir of a run-of-the-river hydroelectric power plant. Such a power plant has considerably less storage than the reservoirs of large dams and conventional hydroelectric stations which can store water for long periods such as a dry season or year.

Why storage and Pondage are required?

Storage and Pondage:

Therefore, some arrangement in the form of storage and pondage of water is required for the proper handling of the flow of water so as to make it available in important quantity to meet the power demand at a given time.

Which hydro power plant is integrate with local power grid?

A micro hydro power (MHP)’plant’ is a type of hydro electric power scheme that produces up to 100 KW of electricity using a flowing steam or a water flow. The electricity from such systems is used to power up isolated homes or communities and is sometimes connected to the public grid.

What type of hydropower plant does not use a dam Mcq?

What type of hydropower plant does not use a dam: Impoundment.

What are the different types of hydro power plant?

Hydropower plants can be classified in three categories according to operation and type of flow:

  • Run-of-river (RoR), …
  • Storage (reservoir)
  • Pumped storage hydro power plants (HPPs) work as energy buffer and do not produce net energy.
  • In-stream Hydropower Schemes use a rivers natural elevation drop without to dam a river.

What is storage in hydro power plant?

Storage hydropower plants include a dam and a reservoir to impound water, which is stored and released later when needed. Water stored in reservoirs provides flexibility to generate electricity on demand and reduces dependence on the variability of inflow.

What is the difference between headrace and tailrace in a hydroelectric power plant?

The used water is released through the tail race. The difference between head race and tail race is called gross head and by subtracting the frictional losses we get the net head available to the turbine for generation of electricity.

What is surge tank in hydro power plant?

A Surge tank is a water storage device used as a pressure neutralizer in hydropower water conveyance systems in order to dampen excess pressure variance. … In short, the surge tank mitigates pressure variations due to rapid changes in velocity of water.

Which type of generator is used in wind power generation?

The type of generator most used in wind turbines are the permanent magnet synchronous generators.

What are the different types of turbines and generators are used in various hydro power plants?

Turbines used in hydroelectric power plants fall into two categories: Impulse and Reaction based. Impulse based turbines include Pelton and cross-flow turbines. Reaction based turbines include three subtypes: Francis turbine, propeller turbine (bulb turbine, Straflo turbine, Kaplan turbine types), and kinetic turbine.

What is the difference between thermal and hydro power plant?

Thermal energy is produced by burning coal, petroleum and Natural gas. Hydroelectricity is produced by fast flowing water with the help of turbines. It uses non-renewable resources to generate electricity. It uses renewable resources to generate electricity.

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 and hydroelectric power plant?

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 structure that houses the turbines and generators, and into which the pipes or penstocks feed, is called the powerhouse.
