Power generation, transmission and protection system equipments of Desh Enrgy Limited

Abstract

Power is well considered as one of the most vital infrastructure capability for growth of country's economy. The significance of power cannot be denied. Socioeconomic development in Bangladesh is causing the increasing demands of electricity day by day. With the appearance of Market Economy, the demand of stable supply of power has become more and more important for trade, commerce, industry and agriculture for success of overall development of the country and alleviation of poverty. Government of Bangladesh agreed in principle to the concept of private sector electricity generation. Government approved this project as a pilot project of private Power Generation. Accordingly a private limited company named Desh Energy Limited was formed and registered on 2000. The company has taken numerous development programs for increasing its generation which is the demand of time. The plant capacity of DEL in Narayanganj is around 100 MW. The objective of our internship at DEL (Desh energy Limited), was to get a clear conception on power generation and transmission. Through this internship we got the opportunity to work as a member of a team which was involved in Fuel section, Generator section, transformer section, and substation. We learned about the protection and switchgear section of generator, transformer, and the whole power plant. We worked for fifteen days in power generation and maintenance system. The power station control system is automated and modernized. Generation, Protection, controlling and transmission to the national grid are the main aim to set up this power plant. There are various processes to produce electricity. Following necessary steps we generate electricity and transmit it to the national grid. We gathered experience in protection of some important equipment related to power generation process, such as generator protection, transformer protection, and substation protection, along with its operating principles, maintenance and testing system. We also gathered experience of controlling a power plant through operating and monitoring from the control room, with the help of our superintendent engineer. Upon completion of this internship, we are able to relate the practical experience with the theoretical knowledge in power sector. It has helped us to understand the practical problems better and their solutions related to several aspects of power plant.
