PROBLEM TO BE SOLVED: To enhance the operating rate of a non-utility generator being operated in parallel with a commercial power supply. SOLUTION: In the receiving power constant control system for supplying power from a commercial power supply or a generator to private loads under receiving power constant control system, a daily timer for altering the set receiving power subjected to constant control is provided on a control board. The set receiving power is set at a low level (200kW) for a time band where the private loads are not disconnected simultaneously and a maximum capacity is not required. The set receiving power is altered to a level (600kW) corresponding to the maximum capacity at a moment of transition to a time band where the private loads are disconnected simultaneously and a maximum capacity is required S4. |
