Abstract

A method determines the overload capacity of a high-voltage device. The method includes creating a load forecast request for a predefined time period, determining an operational state of the high-voltage device by obtaining state parameters, transmitting the load forecast request and the state parameters at a request time to a load-forecasting model, and determining the maximum utilization in the predefined time period by the load-forecasting model, with which the overload capacity of a high-voltage device can be fully exploited. A lifetime consumption of the high-voltage device before the request time is derived from measured values by obtaining an actually consumed lifetime and the actually consumed lifetime is fed to the load-forecasting model as a state parameter. The load-forecasting model then determines the maximum overload capacity depending on the actually consumed lifetime.

First claim

The invention claimed is:

1. A method for determining an overload capacity of a high-voltage device, which comprises the steps of:
creating a load forecast request for a predefined time period;
determining an operational state of the high-voltage device by obtaining state parameters;
transmitting the load forecast request and the state parameters at a request time to a load-forecasting model;
deriving a lifetime consumption of the high-voltage device, before the request time, from measured values by obtaining an actually consumed lifetime of the high-voltage device and by feeding the actually consumed lifetime to the load-forecasting model as a state parameter, wherein the load-forecasting model determines a maximum overload capacity depending on the actually consumed lifetime; and
determining, via the load-forecasting model, a maximum utilization in the predefined time period.

2. The method according to claim 1 , wherein the state parameters include a parameter which maps available cooling power.

3. The method according to claim 1 , wherein the state parameters contain a parameter which maps weather conditions to which the high-voltage device is exposed.

4. The method according to claim 1 , which further comprises continuously calculating the actually consumed lifetime of the high-voltage device and storing the actually consumed lifetime in a storage unit.

5. The method according to claim 1 , wherein the load forecast request contains a forecast of weather conditions.

6. The method according to claim 1 , wherein the load forecast request includes an indication of a desired lifetime consumption.

7. The method according to claim 1 , wherein the load-forecasting model indicates an expected lifetime consumption.

8. The method according to claim 1 , which further comprises:
capturing the measured values using sensors which are disposed in or on the high-voltage device; and
obtaining operational state parameters at least partially on a basis of the measured values and/or values derived therefrom.

9. The method according to claim 8 , which further comprises transmitting the measured values and/or the values derived therefrom via a short-range communication connection from the sensors to a communication unit of the high-voltage device, wherein the communication unit is connectable via a long-range communication connection to a data processing cloud.

10. The method according to claim 9 , which further comprises storing the measured values and/or the values derived therefrom captured before the request time on a storage device of the communication unit or of the data processing cloud.

11. The method according to claim 9 , wherein a geographical location of the communication unit and the high-voltage device connected to it are determined by an antenna for position determination which is disposed in the communication unit, and weather data are then captured by a weather-reporting service, the weather data being provided by a service provider for the geographical location of the high-voltage device.

12. The method according to claim 1 , which further comprises deriving the measured values and/or values derived from the measured values which have been captured or derived before the request time.

13. A non-transitory storage medium carrying computer executable instructions for performing a method for determining an overload capacity of a high-voltage device, the method comprises the steps of:
creating a load forecast request for a predefined time period;
determining an operational state of the high-voltage device by obtaining state parameters;
transmitting the load forecast request and the state parameters at a request time to a load-forecasting model;
deriving a lifetime consumption of the high-voltage device before the request time from measured values by obtaining an actually consumed lifetime of the high-voltage device and by feeding the actually consumed lifetime to the load-forecasting model as a state parameter, wherein the load-forecasting model determines a maximum overload capacity depending on the actually consumed lifetime; and
determining, via the load-forecasting model, a maximum utilization in the predefined time period.

14. A non-transitory storage medium carrying computer executable instructions for performing a method for determining an overload capacity of a high-voltage device, the method comprises the steps of:
