Power Generation, Transmission Distribution and Protections System of the Equipments of Ashuganj Power Station Company Ltd.(APSCL).

Abstract

Development of sources of energy to accomplish useful work is the key to the industrial progress which is essential to the continual improvement in the standard of living of people everywhere. In Bangladesh the demand of power is approximately 5800 MW. Public and private sector produces 63% and 37% of electricity respectively. Public sector produces electricity through Bangladesh Power Development Board (BPDB), Ashuganj Power Station Company LTD (APSCL) and Electricity Generation Company of Bangladesh (EGCB). On the other hand, private sector produces power through small independent power producers and rental that government buys at a constant price. BPDB individually produces 46% of the total production. To fulfill this large demand there are many power stations that are being setup throughout the country. This will reduce the load shedding in the long run. It is expected that this step will also put a contribution to the national economy. To fulfill the large demand of electric power in Bangladesh, the Ashuganj Power Station Company Ltd. (APSCL) plays a vital role in power generation being the second power station in Bangladesh. The APSCL produces 724 MW of electric power and supplies to the national grid. Its contribution to the country is 15% of the total national power generation sector. It has total 8 units. In near future to contribute more in the power system they have plan to setup more units in the power station. It is expected that the power generation in APSCL will be increased by its own property. The mission of this company is to ensure long-term uninterrupted supply of quality power to the consumers in future. The internship in Ashuganj Power Station Company Ltd. (APSCL) covers all the process of power generation, transmission and distribution system of APSCL. During our internship in APSCL, we were taught about the power plant management system in the power station. This large power station (APSCL) has a large number of equipments which was observed by us during the internship period. This report is the attachment of that industrial training. The systems or the devices those were observed during the internship includes generator, boiler, control room, water treatment plant, steam turbine, gas turbine, compressor, backup system, cooling system, transmission system, distribution system, substation equipments like- power transformer, current transformer, potential transformer, protective relays, circuit breakers, underground cable connection, isolator, insulator, lightning arrester and other essential equipments of the APSCL. In this report the main emphasize is given on the explanation of those things along with the acquired knowledge about power generation, transmission, maintenance and distribution system in Ashuganj Power Station Company Ltd. (APSCL).
