Programmable Logic Controllers Based Generator Protection System

Abstract

This research is about generator protection via Programmable Logic Controller. Afield device such as, sensors, current transformer, voltage transformer equipped to used as input signal supply to the PLC input modules, when the generator facing an abnormal condition in one or more of it’s subsystem ,an interface devices send signal to the PLC to proceed, diagnosing steps as programmed and change the output status accordingly. By using LOGO simulator software to protect the generator from the up normal conditions, the program has been tested by simulation and it works properly and gives the desired results.
