Distribution and Maintenance of Grid-Substation of DESCO

Abstract

The power sector of Bangladesh have 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 the independence. But most of these reforms failed to bring the desired outcome 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 problems in the power sector have been with the distribution system, which is characterized by heavy system loss and poor collection performance. However, the distribution system seldom gets the priority in the reform initiatives. To solve these problems, Government of Bangladesh has taken an initiative to unbundle the power sector in the form of The Private Limited Companies. This report is based on my internship activities which I have done at DESCO (Dhaka Electric Supply Company Limited). This report focuses on the operation of DESCO, their vision, supply capacity, financial condition, distribution of electricity and future planning. The Dhaka electric supply company was created as a distribution company in 1996 under the companies act 1994 as a public limited company with an authorized capital of TK. 5 million. At present, DESCO is one of the main power distribution companies in Bangladesh. In total 75% shares of DESCO are owned by Bangladesh Government and rests of the 25% shares are owned by Chairman of DESCO and other shareholders. Internship is such an opportunity to learn those activities that are related to our real engineering world. During my internship period, I have been able to gather some knowledge on grid-substation, transformer and their maintenance and the power factor improvement which are closely related to my study materials. I have also observed their administrative activities of control room; complain room operation, IT (Information & Technology) and one point operation which will surely help me to visualize the effectiveness in my practical life.
