Abstract

At least one centralized transmission facility is connected via the power supply lines of the power supply network to the decentralized transmission facilities with a decentralized repeater function being appropriately positioned in the power supply network in the event of there being insufficient transmission range of the centralized to the decentralized transmission facilities. According to the invention, part of the decentralized transmission facilities are additionally fitted with repeater functions in such a way that they can be configured via the centralized transmission facility as a decentralized transmission facility and/or as a decentralized transmission facility with a repeater function. In this way, if centralized transmission facilities cannot be reached, an alternative path is determined and the transmission system is automatically reconfigured.

Claims

1-8. -8. (canceled)

9. A method for operating a transmission system in a power supply network having at least one centralized transmission facility connected via power supply lines to decentralized transmission facilities, comprising:

providing a decentralized repeater function at an appropriate position in the power supply network for an inadequate transmission range of the centralized transmission facilities to the decentralized transmission facilities; and

providing at least some of the decentralized transmission facilities with repeater functions to be configured when needed in accordance with a network management function in one of the centralized transmission facility, the power supply network and the decentralized transmission facilities, as a function of a network topology of the power supply network and transmission ranges of the decentralized transmission facilities.

10. A method according to claim 9, further comprising, when a decentralized transmission facility is unreachable, automatically configuring other decentralized transmission facilities and the repeater function thereof in accordance with the network management function and the network topology of the power supply network assigned to the network management function to enable communication between the centralized and decentralized transmission facilities.

11. A method according to claim 10, further comprising when one of the decentralized transmission facilities is unreachable

determining an alternative path for the communication of information from the centralized transmission facility to the one of the decentralized transmission facilities using affected decentralized transmission facilities in accordance with the network management function;

and

configuring at least some of the affected decentralized transmission facilities with the repeater function as required by the alternative path.

12. A method according to claim 11, further comprising during at least one of an initialization and a reconfiguration planned as part of one of expansion and reduction of the transmission system, configuring the decentralized transmission facilities and the repeater functions thereof in accordance with the network management function and the network topology of the power supply network assigned to the network management function to achieve a shortest possible transmission path.

13. A method according to claim 9, further comprising

configuring the transmission system with the at least some of the decentralized transmission facilities with the repeater function having a range area and positioned so that alternative paths are available to any unreachable transmission facilities;

and

determining relevant decentralized transmission facilities to be configured with the repeater function thereof when any of the decentralized transmission facilities become unreachable.

14. A transmission system in a power supply network of power supply lines, comprising:

at least one centralized transmission facility; and

decentralized transmission facilities connected via the power supply lines of the power supply network to said at least one centralized transmission facility, including

a first group of said decentralized transmission facilities having a decentralized repeater function and appropriately positioned in the power supply network when there is insufficient transmission range of said at least one centralized to reach all of the decentralized transmission facilities; and

a second group of the decentralized transmission facilities having a configurable repeater function that is configured when needed.

15. A transmission system according to claim 14, further comprising a network management function for configuring said centralized and decentralized transmission facilities.
