POWER PLANT TECHNOLOGY INTRODUCTION AND OVERVIEW Prof. Anand Bhatt
CONTENTS Introduction India’s Energy production scenario Classification Working principles Main Components Syllabus
INTRODUCTION A power plant can be defined as a set of number of components working together simultaneously to convert any of the natural form of energy into electrical energy. Initially, energy is converted into mechanical form and finally it is converted in electrical power. Electrical Energy is the only form of energy which is easy to produce, easy to transport for long distance, easy to use and easy to control. Electrical power consumption per capita is the direct index of development of a country.
CLASSIFICATION Bulk Electrical Power production: (1) Thermal Power Plant (Rankine cycle) -Combustion of solid, liquid or gaseous fuels (2) Nuclear Power plant -By Nuclear fusion or fission (3) Hydraulic power plant -By using the energy of flowing fluid from the dam (4) Gas turbine (Brayton Cycle) -By combustion of fuel (5) Renewable sources for power production -Solar, wind
Renewable sources for Power production: WORKING PRINCIPLES
