Power Generation Plants


• Thermal Power Plants – as the name suggests, these power plants convert heat energy into electrical energy. The working fluid of these plants is mostly steam and they work on the Rankine cycle. A steam power plant consists of a boiler which is used to generate the steam from water, a prime mover like a steam turbine to convert the enthalpy of the steam into rotary motion of the turbine which is linked to the alternator to produce electricity. The steam is again condensed in the condenser and fed to the boiler again.

• Hydro Power Plants – these plants use the kinetic energy of flowing water to rotate the turbine blades, hence converting kinetic energy into electrical energy. These types of power plants are very good for peak loads. Their main disadvantage lies in the fact that their location depends on a number of factors which are beyond the control of human beings such as the hydrological cycle of the region and so forth. If there is shortage of water it could lead to shut down of these plants. For this reason alternative arrangements such as thermal power plants need to be made to ensure uninterrupted generation of power.
