Study on Combined Cycle Power Plant Bangladesh Ghorashal 4th Unit Repowering Project

Abstract

Grorashal power station (GPS) is the largest power station in Bangladesh which plays a major role in the power sector of Bangladesh. GPS produces 950 MW electricity. This station is located on the Eastern bank of river Shitalakkha at North East of Dhaka under Palash, Narsingdi district. I did my internship at GPS 4th unit from 16th September to 15th November 2020. During this period I visited all the sections of the plant and saw different auxiliaries of the plant. I learned about the generation, controlling, and maintenance system of GPS. Sub-station is one of the most major parts of the power plant. I have visited the sub-stations and gathered knowledge about transformers, bus bars, circuit breakers, lightning arresters, current transformer, potential transformer, and other equipment of the substation. During My internship period, I observed and gathered practical knowledge and experiences over the topics which I have learned inside the classroom or from the textbooks. In this report, I have focused on the process which is used in GPS for power generation, distribution and transmission of various equipment, and protection of power system.
