Welcome to Electrical Engineering Articles and Practice tests

Power Plant Engineering

Power plant generates electricity from various sources like hydraulic, thermal, gas, solar, wind etc. In steam power plants the feed water is converted to steam by exchanging the heat from various sources. The converted steam is used to drive the turbine which intern rotates electrical generator and produces electricity. In hydraulic power plants, the water in the dam is diverted to hydraulic turbines which turns the generator and produces electricity. Theses plants works at peak load. In wind power plant, the wind turbines are driven by the high velocity wind which generates electricity.
