ABSTRACT:
A control system is provided for controlling the distribution of load among a plurality of generators with some of those generators responding quickly to control and some being slow in response. The area control error signal is divided into portions to provide a unit error signal assigned to each generator. A control is utilized which responds to the unit error signal to reposition the governor motor until the error signal is reduced to zero. Applying that control to slow responding units requires anticipation of the generation changes to be expected after full response. Control of the governor motor position so as to modify generation is from the unit error signal as modified in accordance with the difference between the desired generation for the units as required for economic considerations and the actual generation with that difference being modified by a signal which is a function of the anticipated generation. That function is expressable in one form by the equation ##EQU1## where: K is a constant
