Excitation Control of Peaking Generator Connected to Large Power System

The factors involved in the parallel operation of alternating current generators are discussed in this paper, with particular emphasis placed on the operating performance of a relatively small peaking generator connected to a large power system. A brief description of the various types of excitation control systems used on these generators is presented, and the merits and disadvantages of each type are reviewed. A listing of the specific requirements of a regulator applied to a peaking generator is made, showing what the authors feel is necessary in an excitation control system for a generator used for both a peaking and a cranking unit. Finally, a typical excitation control system is described with its performance evaluated.
