Abstract
The disclosure relates to a method for monitoring an electricity supply grid, wherein the electricity supply grid has a grid frequency and a grid topology with a plurality of grid nodes, a plurality of converter-controlled infeed units are each connected to the electricity supply grid via a grid connection point, and the grid connection points are distributed over the grid topology, comprising the steps of acquiring in each case at least one node voltage at the grid connection point or at a grid node, assigned to the grid connection point, of the plurality of grid nodes, such that a plurality of node voltages are acquired, wherein each grid connection point or grid node is assigned a location in the grid topology, which is referred to as node location, and the acquired node voltage is characterized by a node phase angle as phase angle of the node voltage, assigning an associated node location to each node voltage, and ascertaining grid statuses distributed over the grid topology from the acquired node voltages, each with an assigned node location, in particular from the node phase angles or phase relationships between at least two grid nodes.
