Career Episode Narrative 2
(Project: Design & development of simulation software for
Computer Aided Power Distribution System Design & analysis)
Introduction:
1.During the final year of my Bachelor of Science degree course in Electrical & Electronic Engineering at Chittagong University of Engineering and Technology, (CUET) Bangladesh. (Erstwhile, Bangladesh Institute of Technology (BIT), Chittagong, Bangladesh.) I had to do a major research project on electrical power distribution system design & analysis titled as ‘Computer Analysis of Distribution System in Bangladesh Power Development Board’ under the supervision of Prof. Dr. M. Shamsul Alam, who was the head of the Department of Electrical & Electronic Engineering of CUET. The time duration of this project was from April to September 2003.

Background:
2.The aim of our project was to design & develop simulation software for Computer Aided distribution system design & analysis. To achieve this goal I had to study about power distribution system design & analysis in depth, I had to read recent journals and publications to know the latest improvement and invention in this field. I also take help from the Internet to collect information. In my project I acquire comprehensive knowledge on the technology used in the existing methodology of load-flow studies. With my team met I was involved in problem definition, mathematical formulation of the equation of load-flow studies involved in distribution system design & analysis, and in software design. I visited the practical site where of Bangladesh Rural Electrification board where this technology can be implemented, to observe how they are working, what are the common problems they are facing and what they are thinking about should be done in this sector. I also met the decision maker in this sector to know about the future plan. Another point, at the time duration of the project work my selected site was not under digital design system. For these reason the work also had a different aspect to think apart from the technological view, the economic and financial aspect also.

3.The need for computational aids in power system engineering led in 1929 to the design of a special-purpose analog computer called au ac network analyzer. By the middle 1950s network analyzers were in operation in the United States and Canada and were indispensable tools to planning, relaying, and operating engineers. The earliest application of digital computers to power system problems dates back to the late 1940s. However, most of the early applications were limited in scope because of the small capacity of the punched card calculators generally in use at that time. In 1957 the American Electric Power Service Corporation completed a large-scale load-flow program for the IBM 704 which calculated the voltages and power flows for a specified power system network.

4.The initial application of the load flow program to transmission planning studies proved so successful that all subsequent studies employed the digital computer instead of the network analyzer. The success of this program led to the development of programs for short circuit and transient stability calculations. Today the computer is an indispensable tool in all phases of power system planning, design, and operation.

5.The great technical advances in the design and production of commercial and scientific general-purpose digital computers since the early 1950s have placed a powerful tool at the disposal of the engineering profession. This advancement has made economically feasible the utilization of digital computers for routine calculations encountered in everyday engineering work. In addition, it has provided the capability for performing more advanced engineering and scientific computations that were previously impossible because of their complex or time-consuming nature.

6.The development of computer technology has provided the following advantages to power system...
