Control and supervisory system for power distribution equipment.

摘要

A novel and improved control and supervisory system for power distribution equipment capable of controlling and/or supervising a plurality of power distribution devices (107) in an extremely simple, high-speed and efficient manner without requiring any vast and full knowledge of permitted and inhibited operations of varying kinds of power distribution devices to be connected, as well as of the control and supervisory procedures therefor. The system is also able to eliminate the inconvenience and troublesomeness of preparing, at a central or main unit, specific control and supervisory programs suited to the respective power distribution devices (107). To these ends, the system comprises a central control and supervisory unit (101) operable to output a control or supervisory command for controlling or supervising a plurality of power distribution devices (107), and a plurality of terminal control and supervisory devices (103) each operable to receive the control or supervisory command from the central control and supervisory unit (101) for generating a control or supervisory signal suited to control or supervise a corresponding one of the power distribution devices (107), and outputting it to the corresponding power distribution device (107). In one embodiment, the control or supervisory command is conceptionally common to the power distribution devices (107). In another embodiment, the control and supervisory command is intrinsic to a corresponding one of the power distribution devices. <IMAGE>
