Abstract

A method monitors an electrical energy supply network or a subnetwork of the energy supply network. Measurement values detected at at least two measurement points of the energy supply network or subnetwork are evaluated. More specifically, phase angle values are evaluated as the measurement values or phase angle values determined using the measurement values are evaluated. A check is carried out based on the phase angle values to determine whether the energy supply network or the subnetwork is operating synchronously, and, in the event of an asynchronism identified based on the phase angle values, an island identification signal to be generated.
