Delayed ramping in the primary control system or local maintenance controller of a gas turbine implemented electrical power plant

摘要

A predetermined time delay of speed setpoint ramping of a gas turbine is imposed at ignition in its primary control system or local maintenance controller in order to compensate for the fixed energy input at ignition which might otherwise greatly increase the possibility of flameout. The imposed time delay results in the increase of an initial turbine speed tracking mode time period for the duration of the time delay.
