Power Generation, Transmission and Protection System Equipments of Siddhirganj EGCB Power Plant

Abstract

We did our internship at Siddhirganj EGCB Power Plant, located on the bank of the river Shitalakha, within the Siddhirganj Power Station premises at Siddhirganj, Narayanganj from 12th of August to the 8th of September. This internship report is the result of those 15 days. The EGCB Siddhirganj Power Station is a newly commissioned power generating plant. It has two generating units, both gas fired, with a peaking capacity of 240MW. Our duration of stay was divided into four sections: generation, instrumentation and control (I & C), mechanical, and electrical. In all of these sections, we were demonstrated how these systems work and what protective measures are taken for them. During our internship, we learned about how electricity is generated, operation of the plant, major equipments like generators, transformers, and switchgear equipments required for distribution of electricity and protection of the plant. We got to learn the importance of protection and switch gear system for the plant and how they work. In the end, our whole internship was the combination of our theoretical and practical knowledge. Protection and controlling of the equipments of the power station is a very important and complicated task. With the help of the plant engineers, we observed the control room operations, and protective equipments such as relays, circuit breakers, lightning arrestors, current transformers, potential transformers, etc. very closely and understood the functions and controlling system of those equipments. All the required information and knowledge was provided to us in a clear way by our mentors at the plant.
