Design and Construction of an Electronic Governor System for Sensitive Diesel Generators by PLC

Diesel engines are used in sensitive military and industrial applications as stationary power sources. In order to stabilize voltage and frequency of connected generator, diesel engine RPM would be controlled accurately. In most cases mechanical methods are used to fix the engine RPM but this method is not very accurate. In this paper a new electronic governor has been designed and constructed with programmable logic controllers (PLC). The designed controller is cheaper, more flexible and more accurate than mechanical governor. It has initially been simulated in MATLAB Simulink which showed adequate results. It was then constructed and installed on a 350 KW diesel generator in which 3.2% improvement over conventional methods was observed.
