Power system governing — The problem

Considerable attention has been focused on the subject of load swings, turbine generator governing, and stability not only when operating a system alone but when interconnected with other systems. At a subcommittee meeting of the power generation committee, two assignments were made: One to crystallize the problem and the other to outline the desirable functional characteristics of a governing system. This memorandum, dealing with the former, has been prepared based on answers to a questionnaire submitted to a representative group of operating companies. The response to the questionnaire was excellent, practically all of the operating companies to whom it was sent having made replies.
