The objective of our internship was to get familiarized with the planning, generation and distribution on the practical field of power sector. The objective was to gain firsthand knowledge on the operations. During internship we got the opportunity to as a member of the engineering team which was involved in Generation, Transformation, Transmission and the CCPP. We came to know about the main principle to set up a power plant and that is Protection, Monitoring and Vision. Among them protection is the most vital and crucial part of a power station. A power station expends a huge part of their earnings behind the protection scheme. Ashuganj Power Station Company Limited (APSCL) holds the second largest power generation in Bangladesh. With its 3 plants comprising of 8 units with an installed capacity of 724 MW providing 15% power to the National Grid. However, it is not producing 724MW power due to technical difficulties. The present de-rated capacity of the plant is 440 MW due to overhauling phase of plant 1’s unit 1, plant 3s unit 3 and one GT of 54MW of the combined cycle power plant.
