Method for designing the network protection of a low-voltage electrical supply network

摘要

The invention relates to a method for designing the network protection (4) of an electrical low-voltage supply network (1) comprising the following steps: determining the real network state of the low-voltage supply network (1) by means of a network state estimation; performing short-circuit current calculations based on the results of the determined real network state; • calculation of the expected current (10.1) and / or the expected voltage (10.2) at the location of the network protection (4), • in particular evaluation of the existing network protection (4), and • redesign of the network protection (4).
