Abstract

The power sector in Bangladesh faced numerous problems characterized by lack of supply capacity, frequent power cuts, unacceptable quality of supply, and poor financial and operational performance of The sector entities. There have been a number of reforms in the power sector in Bangladesh since her independence, but most of these reforms failed to bring desired improvements in the power sector . among the three main components of the power system, recent reform activities were centered on generation and transmission. The most pressing problem in the power sector has been with the dislribution system, which is characterized by heavy system loss and poor collection performance; however, the distribution system seldom got the priority in reform initiatives.

Ashuganj Power Station fulfills about 15% of power requirements of the country. To face the growing requirements for power in the country Government of Bangladesh decided to setup another units of 1000 MW capacities in Ashuganj. Our internship in APSCL (Ashuganj Power Station Company Limited), found on the planning and distribute on the practical field of power sector. Through this internship we got the opportunity to work as a member of a team which was involved in Generator section, transformer section, steam turbine, Gas turbine and combine cycle power plant. In this power station company, various types of work done by us. The superintendent engineer showed us the protection and switchgear section of generator, transformer and turbine. We mainly worked for a long term in the substation section. Control unit of this "nole power station is very enormous. The main aim to set up a power plant, one have to give three things. Protection, Monitoring and Vision. The generation of electricity is one of the most complex processes in the world. After a lot of steps completion we generate it and distribute to the consumers. We gathered some experience in generator protection. We also had some experience to control a largest power plant working in the control room with the help of our superintendent engineer. On the completation of this internship we can relate the practical experience with the theoritical experience in power sector. Overall in our internship, we have gathered lots of knowledge about many real life problems.
