Bangladesh is a densely populated country. Load-shedding is one of the major problems of our country. Now a day, the maximum power demand is almost 4500 MW to 5600 MW and it will rise to 7000 MW in few years. But our power sector provides only 3800 MW to 4600 MW which is one third of the demand. Here, we observed a huge difference. Ashuganj Power Station Company Limited (APSCL) where we have completed our internship is the second largest power plant in Bangladesh. It has 9 units with 777 MW capacities. But its present de-rated capacity is 731MW and dependable capacity is 624MW at a deliver point. Ashuganj Power Station fulfills about 15% of power requirements of the total country. In our internship, we have learnt about the whole power plant system focusing on the Generation section mostly. Here, we came to know how a power station can generate power and how they distribute this power around the country, also about the maintenance and the protection of power system equipments, which are used for generating or distributing power. Here, we were not permitted to operate or touch the equipment but saw how these equipments work. At APSCL, we have seen the control rooms, generator rooms etc. We have also learnt about winding shop, battery room, substation, Combined Cycle Power Plant (CCPP), turbine, boiler, water treatment system etc. We were able to combine our theoretical and practical knowledge and also gain knowledge about the whole power system of Bangladesh.
