Power Generation, Control and Protection System of Ghorashal Power Station

Abstract

We have chosen the industrial training to fulfill the partial requirements of B.Sc. in EEE. We have completed our internship at Ghorashal Power Station (GPS) from 20/08/2016 to 03/09/2016. During this time, we have gathered practical knowledge about power generation, transmission process and power distribution process of GPS. GPS covers all the processes from power generation to power supply to the national grid. The aim of this report is to give a brief description of what we have learnt at GPS. At GPS, there are 6 units with an installed capacity of 950 MW. The present de-rated capacity is 740 MW, but now present generation is 650 MW. We have seen boiler where steam is generated at 350oC temperature. We also have seen furnace where fuel burning process is done at 1800o C. We have seen the turbine, which is coupled with the generator. The two pole generator rotates with the turbine at a speed of 3000 rpm. We have learned about cooling system of generator and also seen different types of pumps which are used in GPS. In the substation part, we have learned about different types of transformers such as power transformer, auto transformer, instrument transformer and auxiliary transformer and their cooling system. We have observed the protection equipment and switchgear equipment of GPS. We have seen how to control and maintain the particular units of power generation from control room. We have gathered practical knowledge from GPS during our internship period, which will play a vital role to build our career.
