Abstract
Provided is a method for monitoring a three-phase electricity supply grid. The grid has a topology with spatially distributed grid nodes. Grid nodes are in the form of observation nodes at each of which at least one voltage is acquired in terms of absolute value and phase. The method includes acquiring in each case at least one node voltage at each observation node, where each node voltage has is a node phase angle as phase angle of the node voltage, and each node phase angle describes a respective phase angle with respect to a reference phase angle of a voltage. The method includes ascertaining at least one phase angle relationship that describes a relationship between at least two of the node phase angles distributed over the grid topology, and checking the electricity supply grid for a grid disturbance on the basis of the at least one phase angle relationship.
