Abstract
I have completed my vocational training during the period 09-06-2014 to 08-07-2014 from
RGTPP,Jaisalmer. In this report the main emphasis is on the Power Generation Process.
In the starting of this report the introductory aspects of RGTPP allover India has been
covered. Later I have explained the principle of operation and basic equipments used for the
generation of power.
Recognizing its excellent performance and vast potential, Government of the India has
identified RGTPP as one of the jewels of Public Sector 'Navratnas'- a potential global giant.
Inspired by its glorious past and vibrant present, RGTPP is well on its way to realize it's
vision of being "A world class integrated power major, powering India's growth, with
increasing global presence".
A Combined Cycle Power Plant produces high power outputs at high efficiencies (up to 55%)
and with low emissions. In a Conventional power plant we are getting 33% electricity
only and remaining 67% as waste. By using combined cycle power plant we are getting 68%
electricity. The basic principle of the Combined Cycle is simple: burning gas in a gas turbine
(GT) produces not only power – which can be converted to electric power by a coupled
generator – but also fairly hot exhaust gases.
