Pumped storage unit.
Pumped storage units have two basic functions: pumping water and generating electricity. When the electrical system is at maximum load, the turbine operates and the opening of the turbine guide vanes is adjusted via the governor system to convert the potential energy of the water into mechanical energy for the rotation of the unit, then the mechanical energy is converted into electrical energy using the generator.
The water pump works when the electrical system load is low, and the electrical energy during the low valley is used to pump water from the lower tank to the upper tank through automatic adjustment of the speed. Regulation system, the opening of the guide vane is automatically adjusted according to the lift of the water pump, and the electrical energy is The potential energy converted into water is stored.
