Method and system for monitoring the operating state of an energy supply network

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.
