Abstract

A method monitors an operating state of an energy supply network. Measurement values indicating an operating state are detected using sensors which are provided at measurement points paired with primary components of the energy supply network, and a visualization indicating the operating state of the energy supply network at each measurement point is generated using a monitor. The aim is to minimize the configuration and parameterization complexity for the operator of the energy supply network. The measurement values are transmitted from the sensors to an application server. The measurement values are analyzed, thereby forming system status values, the system status values indicating the operating state of the energy supply network at the measurement points. The system status values are transmitted to the monitoring device and a visualization which indicates the operating state of the energy supply network is generated by the monitoring device using the system status values and displayed.

acquiring measured values indicating the operating status of the energy delivery network from sensors disposed at measurement locations assigned to primary components of the energy delivery network;

transmitting the measured values or values derived from the measured values first to an application server, disposed outside a sphere of influence of an operator of the energy delivery network;

analyzing and/or processing the measured values or the values derived therefrom via the application server, thereby forming system status values indicating the operating status of the energy delivery network at a measurement location of a respective sensor;

transmitting the system status values from the application server to a monitoring device of the operator of the energy delivery network; and

generating, via the monitoring device of the operator of the energy delivery network, a visualization that indicates the operating status of the energy delivery network at the measurement location of the respective sensor 12a-c), based on at least one of the measured values, the values derived therefrom or the system status values received from the application server.

17. The method according to claim 16, which further comprises:

providing each of the sensors with a long-range communication device; and

transmitting the measured values or the values derived therefrom from the sensors to the application server using a long-range communication link established by the long-range communication device.

18. The method according to claim 16, which further comprises:

providing each of the sensors with a short-range communication device;

establishing a short-range communication link to a transmission component by means of the short-range communication device for transmitting the measured values the sensors have acquired or the values derived therefrom to the transmission component; and

transmitting, via the transmission component, the measured values received or the values derived therefrom to the application server.

19. The method according to claim 16, wherein the sensors attach to the measured values to be transmitted to the application server or the values derived therefrom a unique sensor identifier and/or position information identifying a geographical position of the measurement location of the respective sensor concerned.

20. The method according to claim 16, which further comprises:

transmitting, via the sensors, the measured values to the application server;

checking via the application server the measured values received with regard to their position in an admissible operating range of a respective primary component to which the respective sensor concerned is assigned; and

forming the system status values according to a result of the checking step via the application server.

21. The method according to claim 16,

checking, via the sensors, the measured values themselves with regard to a position of the sensors in an admissible operating range of a particular primary component to which a sensor concerned is assigned;

forming via the sensors values derived from the measured values acquired according to a result of the checking;

transmitting derived values to the application server via the sensors; and

forming the system status values via the application server using the derived values received.

22. The method according to claim 16, which further comprises:

providing from the application server topology information describing a layout of the energy delivery network; and

forming via the application server the system status values, the application server using the measured values received or the values derived therefrom and the topology information to form the system status values by assigning a graphical representation of the operating status of the energy delivery network at the measurement location of the respective sensor to a position in the topology information, the position corresponding to the measurement location.
