SUMMARY
The discussion centers on a power plant experiencing a load spike when operating seven 3.5MW diesel engines in droop mode. One engine, which previously suffered a generator blast, suddenly dropped to zero kW and then quickly returned to full load. The issue may stem from a governor or fuel pressure problem, compounded by a communication failure that caused the emergency stop to malfunction. Additionally, the control system's hardware panel was found to be improperly grounded, potentially contributing to the operational instability.
