Laboratory Model to Teach Operation of Power Systems

A laboratory model of power system is developed to demonstrate the operational aspects of power systems for the under graduate students in electrical discipline. Conventional methods of class room teaching and simulation based experiments are used by most of the engineering colleges to teach power systems. The teaching community feels difficult to give physical insight and evaluation of power system, which can be attained only through laboratory based experiments. This paper explains about the development of scaled down model of three bus system with slack, PV and PQ bus. The procedure of demonstrating the operational aspects of power system like grid restoration, bus properties, Q limit violation, power flow control and frequency management are also discussed. This laboratory based teachings gives better understanding about power system and make the students to analyze and evaluate the system effectively.
