Abstract

A method for monitoring an operating state of an energy supply network connects a data processing cloud to selected communication units at a query time over long-range communication connections. Selected communication units transmit measured values and/or values derived therefrom to the data processing cloud over a long-range connection. To receive measured values and/or values derived therefrom, each communication unit is connected, over a short-range communication connection, to at least one sensor on or in a high-voltage device of the network for capturing measured values. The data processing cloud determines the network operating state within an analysis based on measured values and/or values derived therefrom. To provide a simple and cost-effective analysis of the entire network operating state, the data processing cloud during analysis uses measured values and/or values derived therefrom from at least two selected communication units at different locations.

First claim

The invention claimed is:

1. A method for monitoring an operating state of an energy supply network, the method comprising:
connecting a data processing cloud to a number of selected communication units over long-range communication connections at an interrogation time;
using each selected communication unit to transmit at least one of measured values or values derived from the measured values to the data processing cloud over one of the long-range communication connections;
placing at least one sensor on or in a high-voltage device of the energy supply network to acquire the measured values, and connecting each communication unit over a short-range communication connection to the at least one sensor to obtain at least one of the measured values or the values derived from the measured values;
using the data processing cloud to determine the operating state of the energy supply network in an analysis based on at least one of the measured values or the values derived from the measured values; and
during the analysis, using the data processing cloud to take into account at least one of the measured values or the values derived from the measured values originating from at least two selected communication units installed at different locations.

2. The method according to claim 1 , which further comprises using at least one of the measured values or the values derived from the measured values originating from different high-voltage devices, to influence the analysis.

3. The method according to claim 1 , which further comprises using at least one of the measured values or the values derived from the measured values originating from measuring points of different locations, to influence the analysis.

4. The method according to claim 1 , which further comprises simulating dynamic processes based on the analysis.

5. The method according to claim 1 , which further comprises carrying out the analysis by using at least one algorithm simulating an intelligent behavior or artificial intelligence.

6. The method according to claim 1 , which further comprises, during the analysis, using at least one of the measured values or the values derived from the measured values having been at least one of acquired or derived before an interrogation time.

7. The method according to claim 6 , which further comprises storing at least one of the measured values acquired before the interrogation time or the values derived from the measured values acquired before the interrogation time, on a storage unit of the communication unit.

8. The method according to claim 6 , which further comprises storing at least one of the measured values acquired before the interrogation time or the values derived from the measured values acquired before the interrogation time, on a memory of the data processing cloud.

9. The method according to claim 1 , which further comprises using the data processing cloud to generate a visualization of the operating state of the energy supply network based on the analysis.

10. The method according to claim 9 , which further comprises representing a map during the visualization, and schematically illustrating on the map the high-voltage devices connected to the selected communication units.

11. The method according to claim 1 , which further comprises generating a prediction about a further course of a capacity utilization and lifetime of the high-voltage devices and representing the prediction in the visualization, based on at least one of the measured values acquired before an interrogation time or values derived from the measured values acquired before the interrogation time.

12. The method according to claim 1 , which further comprises using a position determining antenna disposed in a communication unit to determine a geographical position of a respective communication unit and of the high-voltage device connected to the respective communication unit, and subsequently acquiring weather data provided for the geographical position of the high-voltage device from a service provider using a weather news service.

13. A non-transitory computer program product, comprising instructions stored thereon, that when executed on a processor, perform the steps of claim 1 .

14. A non-transitory computer-readable medium storing a computer program according to claim 13 .
