Combined Cycle Power Plant and Substation of Ashuganj Power Station Company Limited (APSCL)

Abstract

As a part of the requirement of B.Sc in Electrical Electronic and Engineering, we went through the procedure of electricity production, distribution and transmission system of Bangladesh in the following internship report. During our internship program, we have visited the second largest power station in Bangladesh that is Ashuganj Power Station Company Ltd and cultured several important features about APSCL. For instance, there are 9 units with installed capacity of 777 MW. Approximately 15%of the total demand for power (electricity) is met by APSCL. This internship program has opened a window of opportunity for us, as student of EEE department at East West University to validate, our theoretical knowledge with the field experience. We have observed different equipments and have learned different procedures of maintaining power station to run them efficiently and safely. This includes generator, boiler, water treatment plant, steam turbine, gas turbine, compressor, backup system. In addition we have also observed substation equipments such as power transformers, current transformer, potential transformer, protective relays, circuit breakers, insulator, lightning arrester and other key equipments. With the aid of this report, we primarily focus on the details of Combined Cycle Power Plant by incorporating the knowledge about power generation, transmission, maintenance and distribution system at Ashuganj Power Station Company Ltd.
