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.
Electrical Power system
Electricity is the hear of the on growing industrial sector. The electricity generated at power plants are transferred to the industries and household purposes. The major components of electrical system are Electrical Gr]generator, Electrical motor, Electrical transformer, Distribution system and circuit breaks etc.
