PURPOSE:To improve the stability and reliability of power supply by performing a demand control and a private power generator control in parallel with each other. CONSTITUTION:When the quantity of power consumed exceeds a contract demand, a load-interrupting signal is given from CPU 2 to a communication controller 3, further transmitted to an input-output device 5C via a transmission line, and sent from said input-output device 5C to a corresponding breaker 9 so that a load is interrupted and the so-called demand control is performed. On the other hand, a generator-controlling signal is given from CPU 2 to the communication controller 3, and thereafter sent from an input-output device 5A to a generator control device 6 via said transmission line so that a generator 7 is controlled. Therefore, when a large load change occurs in a time zone where a contract command is small, a supply capability can be kept almost constant if this generator 2 is controlled in parallel. |
