What is Hydro Turbine Generator?

The Hydro Turbine Generator is a device that converts the energy from moving water into power. Hydro Turbine is additionally called a water turbine. Hydro Turbine generators are often effectively using a vast array of water sources: a small stream, a quickly flowing river, a waterfall, a lake, and even from the oceans. There are many various sizes and designs of hydro turbines, each developed from differently tested strategies for collecting the energy from a water source. If correct conditions are met for a hydro turbine generator to be constructed and used, electricity may be obtained efficiently, cleanly, and for an occasional cost.

Hydraulic turbines convert hydraulic energy or we will say that energy of water (kinetic and pressure energy of water) into energy. This energy is further wont to drive a generator which converts it into power. The fundamental concept of this kind of turbine is that water flowing from a dam generates a pressure force while passing through the turbine. This pressure force is used to rotate the turbine which further rotates the generator and convert hydraulic energy into power.

Working Principle:

A force is directly proportional to the change in momentum. So if there's any change in momentum of fluid a force is generated. Within the hydraulic turbine blades or bucket (in case of Pelton wheel) are provided against the flow of water which change the momentum of it. Because the momentum changes a resulting pressure force is generated which rotates the rotor or turbine. The foremost important phenomenon is that the amount of change in the momentum of water is directly proportional to force. Because the change in momentum is high the force generated is high which increases the energy conversion. Therefore the blade or buckets are designed so they can change the maximum momentum of the water. This is often the fundamental principle of Hydro Turbine Generator. These turbines are used as hydro-electrical power plants.

Types of Hydro Turbine:

When hydro turbine generator converts energy into voltage with the assistance of moving water, is named a hydro turbine generator. It’s employed in differing types of hydro-power stations. In this kind of hydro station, water pressure may vary consistent with the supply of water. It should be artificial or natural. The water resource is coming from various forms of the river, lake, waterfall, etc. in step with the turbine size, the hydropower systems are two types.

1. Hydraulic Head:

A high head hydro turbine may be a hydropower system during which the water traveling through the turbine originates from a significantly higher elevation. A high head hydro turbine system requires less volume of water flow to control because the momentum collected from gravity through the longer distance of falling water makes up for the loss of volume.

2. Low head hydropower system:

Low-head hydropower refers to the event of hydroelectric power where the top is often but 20 meters, although precise definitions vary. Head is that the vertical height measured between the hydro intake water level and also the water level at the purpose of discharge.

Always remember that Hydropower stations are differing kinds per the water system. You’ll be able to make use of the little hydro turbine generator for the low headwater system and a large hydro turbine generator for the top headwater system. The foremost important aspect of the water turbine is that the volume of a waterfall and the height of the vertical drop of the water to the turbine. In this system, water is coming from the penstock and falls under the turbine blade. Now turbine starts to rotate. Here K.E. of water converts into the energy and it's supplied to the turbine generator which is connected by a shaft to the turbine. The generator supplies current.

Advantages and Disadvantages:

Hydro turbines are widely used for the last decades. It’s an efficient renewable energy source. There are many ups and downs in every project so there also are have many advantages and downsides which are described below.


• It may be a renewable energy source. Water energy may be used again and again.
• The running cost of the turbine is a smaller amount compared to others.
• It has high efficiency.
• It is often control fully. The gate of the dam is closed once we don't need electricity and maybe open after we needed.
• Dams are used from a very long time so it is used for power generation.
• It doesn't pollute the environment.
• It is simple to take care of.
• The dam constructed for hydraulic turbine can become a tourist place.


• Initial cost is incredibly high. It takes several decades to become profitable.
• It can destroy the natural environment at the site. Large dams cause big geological damages.
• It can develop at only a few sites where the proper amount of water is obtainable.
