The emergence of unexpected incidents in electrical power systems (EPSs) has led to partial disruptions of the national electricity grid, necessitating the deployment of emergency diesel generators (EDGs) to restore power supply to affected areas. This study aims to evaluate the operational effectiveness of three distinct EDG power plants associated with an oil facility and a nearby gas platform during power outages, specifically focusing on scenarios that involve starting power transformers (PTs) and induction motors (IMs). Through the application of technical specifications provided by Stamford Company and the utilization of the EMTP-RV software tool, the EDGs, featuring identical excitation systems and governor parameters, were systematically modeled and analyzed for comparative purposes. The results of this comparative investigation are anticipated to yield significant cost reductions for power plant operations while enhancing overall system safety.
