Classification of hydro power plant according to head
What are the classification of hydropower?
There are three types of hydropower facilities: impoundment, diversion, and pumped storage.
What is head of hydro power plant?
Head is the change in water levels between the hydro intake and the hydro discharge point. It is a vertical height measured in metres. The two diagrams below show how the head would be measured on a typical ‘low head’ and a typical ‘high head’ site.
What are the classification of power plants?
Power plants are classified into those using traditional and nontraditional energy resources. The former type includes thermal power stations (TPS), nuclear power plants (NPP), hydraulic power plants (HPP), and hydro pumped storage power plants (HPSPP).
What is net head and gross head?
The net head is defined as the gross head minus all pipe losses due to friction and turbulence and is used to calculate the available power capacity of the water resource. To determine the net head, the river’s gross head must be measured and pipe loses calculated.
What are the four main types of hydro power plants?
Hydropower schemes can broadly be classified into four main types: run-of-river (RoR), storage (reservoir-based), pumped storage hydro (PSH), and in-stream (hydrokinetic) technologies.
What are the 3 types of power systems?
There are three basic types of distribution system designs: Radial, Loop, or Network. As you might expect, you can use combinations of these three systems, and this is frequently done. The Radial distribution system is the cheapest to build, and is widely used in sparsely populated areas.
What is hydro power plant?
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. Conventional hydroelectric facilities include: Run-of-the-river systems, where the force of the river’s current applies pressure on a turbine.
How many types of power plant are there?
They can be categorized into three different types; impoundment, diversion and pumped storage.
What are examples of hydropower?
For example:
- A hydroelectric dam captures energy from the movement of a river. …
- Wave power captures energy from waves on the surface of the ocean using a special buoy or other floating device.
- Tidal power captures the energy of flowing waters with the help of turbines as tides rush in and out of coastal areas.
How many types of hydro turbine are there?
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.
What are the sources of hydropower?
Hydropower, or hydroelectric power, is a renewable source of energy that generates power by using a dam or diversion structure to alter the natural flow of a river or other body of water.
What is high head turbine?
High Head. Head differences of 100 meters or higher are considered high head. In this type of plant, water travelling through the turbine comes from a significantly higher elevation, meaning that the system needs a smaller volume of water to produce an equivalent amount of energy.
What are the 3 types of water turbines?
Three main types of turbines are used based on the capacity and height difference of the water: Francis, Pelton and Kaplan.
Which turbine is used for high head?
Detailed Solution. From the above table, it is clear that the Pelton Wheel turbine is used where a high head is required.
What is low head and high head?
Though there is no rule regarding water head height but below 30 meters is considered as low head,above 30 meters to 300 meters is called medium head and above 300 meters is known as high head hydro electric power plant.
What is high head and low head in turbine?
Detailed Solution
| Type of head | Head under which it works and example |
|---|---|
| Low head turbine | Operates in the head range of fewer than 45 meters. Kaplan turbine is one of these turbines If the head is less than 3 meters, it is considered an ultra-low head. |

Is example of low head turbine?
Low head turbine: The net head is less than 30m and also these turbines require a large quantity of water. Example: Kaplan turbine.
