HARDWARE IN THE LOOP SIMULATION AND TESTING OF VOLTS PER HERTZ PROTECTION SCHEME FOR A GENERATOR OVEREXCITATION SYSTEM

The over-excitation circumstances that affect generators as well as its protection mechanisms were the subject of this study. This research work developed logic diagram for volts per hertz protection relay to prevent over-excitation conditions in a generator. The hardware in the loop test-bed is implemented to test the volts per hertz protection schemes. The Hardware-in-the-Loop (HIL) test bed was implemented using Real Time Digital Simulator

(RTDS) and SEL 700G IED.
