Abstract:
We did our internship at Ashuganj Power Station Company Ltd (APSCL) located on the
left bank of the river Meghna from 26th of Dcember to 11th of January and this internship report is the result of those 15 days attachment with the APSCL. Ashuganj Power Station Company Ltd. (APSCL) owns the second largest power station in Bangladesh. Ashuganj Power Station fulfills about 15% of power requirements of the country. The installed capacity by its 9 units is 777 MW. Our duration of stay was divided to work in five sections as generator,sub-station, ccpp, I & C and operation. During our internship we gathered practical knowledge about production of electricity, operation, ccpp, major equipments e.g. Generator, Transformer and Switchgear equipments required for distribution and protection of the system. 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 and protective equipments such as: relays (digital and electrical), circuit breakers etc very closely and understood the functions and controlling system of those equipments. Substation is an important part of a power station to distribute power and protection purpose. We acquired knowledge about various types of transformers, bus-bars, circuit breakers (SF6 and Oil), lightning arresters, CT, PT and other equipments of the substation which were clearly taught and shown by the senior engineers of the substation of APSCL.
