Programmable Logic Controller based Automatic Voltage and Frequency Control of MicroGrid

Abstract

The Electrical Grid (EG) is considered to function as an arrangement residing of distribution, transmission and generation with the help and support of different controlling devices to sustain system constancy, productivity & reliability. Operation and control of three phase MicroGrid is about productive control and monitoring. This involves the stability of voltages and frequency at generator Bus Bar (BB). This is effectuated by maintaining the field excitation voltages of Synchronous Generator (SG) to have 380V/440V at the BB. Furthermore, frequency at the Bus Bar is maintained at approximately 50Hz by supervising the speed of prime mover. Over and done with these projects, the undergraduate students, in accumulation to triumph used to with the fundamentals of Electrical Machines. For the institution, excellence laboratory instrument was established at a low cost; it is rigid, reliable and provides maximum learning outcomes of MicroGrid. Inclusion of Synchronous Machine based Distributed Generator's to enhance stability of MicroGrid which is its biggest concern.
