Abstract

A novel and improved control and supervisory system for power distribution equipment including a plurality of terminal control and/or supervisory devices each capable of controlling and/or supervising a plurality of power distribution devices in an extremely simple, high-speed and efficient manner without requiring any central control and/or supervisory unit. To such control and/or supervisory operation, no vast and full knowledge of permitted and inhibited operations of varying kinds of power distribution devices connected therewith, as well as of the control and supervisory procedures therefor, is required. To these ends, each of the terminal control devices comprises a control and/or supervisory instruction section operable to output a control or supervisory command for controlling or supervising a plurality of power distribution devices, and a control and/or supervisory section operable to receive the control or supervisory command from the control and/or supervisory instruction section for generating a control or supervisory signal suited to control or supervise a corresponding one of the power distribution devices, and outputting it to the corresponding power distribution device. In one embodiment, the control or supervisory command is conceptually common to the power distribution devices. In another embodiment, the control and supervisory command is intrinsic to a corresponding one of the power distribution devices. Thus, there is no need for a sender terminal device to prepare specific control and supervisory programs suited to the respective power distribution devices.

Claims

1. A control and supervisory system for power distribution equipment including a plurality of terminal control devices each controlling a corresponding power distribution device connected therewith, each of said terminal control devices comprising:

control instruction means in each terminal device operable to generate and output a control command for controlling said plurality of power distribution devices, the control command being conceptually common to the power distribution devices; and

control means operable to receive the control command from said control instruction means for generating a control signal suited to control a corresponding one of said power distribution devices, and outputting it to said corresponding power distribution device.

2. A control and supervisory system for power distribution equipment as claimed in claim 1, wherein each of said terminal control devices includes alarm instruction means for outputting an alarm command to the other terminal control devices.

3. A control and supervisory system for power distribution equipment as claimed in claim 2, wherein each of said terminal control devices outputs a control command from its control instruction means when it receives an alarm command from one of the other terminal control devices.

4. A control and supervisory system for power distribution equipment as claimed in claim 3, wherein said alarm command is conceptionally common to said power distribution devices.

5. A control and supervisory system for power distribution equipment including a plurality of terminal control devices connected therewith, each of said terminal control devices comprising:

supervisory instruction means in each terminal control device operable to output a supervisory command for supervisory command for supervising a plurality of power distribution devices, the supervisory command being conceptually common to the power distribution devices; and

supervisory means operable to receive the supervisory command from said supervisory instruction means for generating a supervisory signal suited to supervise a corresponding one of the power distribution devices, and outputting the supervisory signal to a corresponding power distribution device.

6. A control and supervisory system for power distribution equipment as claimed in claim 5, wherein each of said terminal supervisory devices includes alarm instruction means for outputting an alarm command to the other terminal supervisory devices.

7. A control and supervisory system for power distribution equipment as claimed in claim 5, wherein each of said terminal supervisory devices outputs a supervisory command at its supervisory instruction means when it receives an alarm command from one of the other terminal supervisory devices.

8. A control and supervisory system for power distribution equipment as claimed in claim 7, wherein said alarm command is conceptionally common to said power distribution devices.

9. A control and supervisory system for power distribution equipment including a plurality of terminal control devices each controlling a corresponding power distribution device connected therewith, each of said terminal control devices comprising:

control instruction means in each terminal control device operable to output a control command for controlling a plurality of power distribution devices, the control command being intrinsic to a corresponding one of said power distribution devices; and

terminal control means operable to receive the control command from said control instruction means for generating a control signal suited to control a corresponding one of the power distribution devices, and outputting the control signal to a corresponding power distribution device.

10. A control and supervisory system for power distribution equipment as claimed in claim 9, wherein each of said terminal control devices includes alarm instruction means for outputting an alarm command to the other terminal control devices.

11. A control and supervisory system for power distribution equipment as claimed in claim 10, wherein each of said terminal control devices outputs a control command from its control instruction means when it receives an alarm command from one of the other terminal control devices.

12. A control and supervisory system for power distribution equipment as claimed in claim 11, wherein said alarm command is intrinsic to a corresponding one of said power distribution devices.

13. A control and supervisory system for power distribution equipment including a plurality of terminal supervisory devices each supervising a corresponding power distribution device connected therewith each of said terminal supervisory devices comprising:

supervisory instruction means in each terminal supervisory device operable to output a supervisory command for supervising a plurality of power distribution devices, the supervisory command being intrinsic to a corresponding one of said power distribution devices and

supervisory means operable to receive the supervisory command from said supervisory instruction means for generating a supervisory signal suited to supervise a corresponding one of said power distribution devices, and outputting it to said corresponding power distribution device.

14. A control and supervisory system for power distribution equipment as claimed in claim 13, wherein each of said terminal supervisory devices includes alarm instruction means for outputting an alarm command to the other terminal supervisory devices.

15. A control and supervisory system for power distribution equipment as claimed in claim 14, wherein each of said terminal supervisory devices outputs a supervisory command from its supervisory instruction means when it receives an alarm command from one of the other terminal supervisory devices.

16. A control and supervisory system for power distribution equipment as claimed in claim 15, wherein said alarm command is intrinsic to a corresponding one of said power distribution devices.
