Design and Development of Virtual Instrument (VI) Modules For Electrical Power Systems Course

Abstract

The study of electrical power systems requires a good background on advanced mathematics and since most of the engineering technology programs don't require advanced mathematics, it is difficult to teach electrical power systems in these programs. A problem for electric power system students is the solution of problems in textbooks through the use of routine problem solving techniques such as equations and formulae. But the students’ over reliance upon formulae and routine use of technique in problem solving too often lead to poor performance in real world scenarios. Also, the students’ lack of comprehension of mathematical concepts results in time wastage during laboratory experiments, misinterpretations of lab data and underachievement in standardized science and engineering tests that stress the fundamentals. This problem can be effectively addressed by improving the student’s conceptual understanding and comprehension of the topics through interactive learning and teaching with virtual instruments (VI) software package like LabVIEW.

This paper will discuss design and development of interactive instructional modules (VIs) for studying (a) Basic Three Phase and Single Phase Circuits, (b) Modeling of Transmission Lines, (c) Simple Economic Dispatch Problem and (d) steps to solve Load Flow problems through Newton Raphson Method.

I. Introduction

The engineering, science, and technology field at present is very dynamic. This is due to the recent advances in computer and other technologies. These advances are resulted in number of computer programs to solve traditional and novel problems. These programs use the computer's increased computational capabilities and assist in the design, development and control of complex systems in matter of minutes. Automation is becoming a part and parcel of every industry and industries need trained workforce to manage this new development. As a result, the engineering, technology, and science programs are under pressure to incorporate use of computers into their curriculum so that their graduates can be well trained in the use and application of these changing technologies and serve the needs of the industrial community. This is especially true for the electric power industry. Because of the recent advances in computer and other technologies, the complexity in all areas of the electrical power industry (generation, transmission, distribution, control, protection, reliability, economics, etc) has increased and the graduates of engineering and technology must be well trained to address the needs of the industry. To address this need, most of the engineering programs and some of the engineering technology programs have introduced courses, programs, and laboratories in power systems to
