How does a turbine work in a dam

WebCross-section view of a generating unit. The role of the turbine is to transform the energy of water, steam or wind into mechanical energy that will make the generator spin. The generator transforms the mechanical energy into electricity. In hydropower plants, this combination of generator and turbine is called a generating unit. Flowing water is directed on to the blades of a turbine runner, creating a force on the blades. Since the runner is spinning, the force acts through a distance (force acting through a distance is the definition of work). In this way, energy is transferred from the water flow to the turbine. Water turbines are divided into two groups: reaction turbines and impulse turbines. The precise shape of water turbine blades is a function of the supply pressure of water, and the t…

WebDec 21, 2024 · Hydropower works by harnessing the energy that comes from the flow of water through a turbine connected to a generator, thus turning it into electricity. Most hydropower plants store water in a dam, which is controlled by a gate or valve to measure the amount of water that flows out. WebNear the bottom of the dam wall there is the water intake. Gravity causes it to fall through the penstock inside the dam. At the end of the penstock there is a turbine propeller, which is turned by the moving water. The shaft from the turbine goes up into the generator, which produces the power.

WebThey often used large dams that block the water's flow, creating a pool of water above the structure. One or more pipes give that pooled water a path to surge downhill. And as the water rushes through those pipes, it spins a turbine, which runs a generator that sends clean electricity to your home. WebA hydroelectric dam converts the potential energy stored in a water reservoir behind a dam to mechanical energy—mechanical energy is also known as kinetic energy. As the water flows down through the dam its kinetic energy is used to turn a turbine. The generator converts the turbine’s mechanical energy into electricity.
