Abstract :
WHEN Oswego Steam Station of the Niagara Mohawk Power Corporation was being designed in the late 1930´s, a unit system was decided upon, a unit consisting of a boiler, turbine, and generator. No steam, feed water, or electric interconnections at greater voltage were provided between units. The merits of the unit system in this case have been described elsewhere.1 The controls for such a station required an entirely new approach and presented an opportunity for major improvement.
