Abstract:
1. A method of controlling a power generating unit using a feedforward control signal developed from a load demand set point signal indicating a desired output of the power generating unit, comprising: determining a magnitude of a rate of change of the load demand set point signal during a particular period of time prior to a current time; comparing the determined magnitude of the rate of change of the load demand set point signal during the particular period of time to a threshold; creating the feedfoward control signal with a fast response rate characteristic when the determined magnitude of the rate of change of the load demand set point signal during the particular period of time is below the threshold and creating the feed forward control signal with a slow response rate characteristic when the determined magnitude of the rate of change of the load demand set point signal during the particular period of time is greater than the threshold; and using the feedforward control signal to control the power generating unit.
