Abstract
A fuel control schedules fuel to a gas turbine to produce a scheduled speed profile during startup. The scheduled speed profile is continuously compared to actual turbine speed during startup, and the difference is compared to an alarm setpoint and a trip setpoint. Normally, temperature and surge limit controls prevent the turbine from accelerating too fast; and, if the turbine is accelerating too slowly, an alarm output is generated when the actual/desired speed difference reaches the alarm setpoint and the turbine is tripped when the actual/desired speed difference reaches the trip setpoint.
