Closed loop rotational speed control system for gas turbine engine electric generator

摘要

A load connection command signal is utilized to raise the rotational speed of a power turbine of an electric generator above a rated speed thereof while the same signal is used to connect load to the generator after a predetermined period of time. A load disconnection command signal is utilized to lower the rotational speed of the power turbine below the rated speed while the same signal is used to disconnect load from the generator with a time delay.
