Wind turbines operate by transforming the kinetic energy in wind into mechanical power which is used to generate electricity by spinning a generator. These turbines can be on land, or can be offshore wind turbines.
Principle of Operation of Turbine Generator – Electricity Generation. Most of nuclear power plants operates a single-shaft turbine-generator that consists of one multi-stage HP turbine and three parallel multi-stage LP turbines, a main generator and an exciter. HP Turbine is usually double-flow impulse turbine (or reaction type) with about 10 stages with shrouded blades and produces about 30 ...
Gas Turbine transforms the chemical energy in the fuel, for example, natural gas or the similar fuel into mechanical energy. The mechanical energy generated by the Turbine exit shaft is then transferred through a gearbox to the Generator’s shaft. Now my generator can create electrical energy.
Kinetic energy turbines, also called free-flow turbines, generate electricity from the kinetic energy present in flowing water rather than the potential energy from the head. The systems may operate in rivers, man-made channels, tidal waters, or ocean currents. Kinetic systems utilize the water stream's natural pathway.
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884.
This steam passes through a turbine containing thousand of propeller-like blades. At the end of these propellers, a generator sits mounted at one of the turbine shafts. When the generator’s coils are rotated in a strong magnetic field, electricity is created. The electricity generated is transported at higher voltages via power line grids.
