METHOD AND ASSEMBLY FOR LOCATING FAULTS IN ELECTRIC DISTRIBUTION NETWORKS

摘要

The invention relates to a method and an arrangement for the local containment of disturbances in distribution networks (1), in particular electrical distribution networks. Method for locally limiting interference (X) in an electrical distribution network (1) having a receiving unit (9.1, 9.2, 9.3) comprising a position determination module and having a database (12) containing position information about devices connected to the distribution network (4.1) 4.11) emitting from the receiving unit (9.1, 9.2, 9.3) identifiable and the respective device (4.1-4.11) assignable radio signals, comprising the steps:a. Determining the active devices (4.1-4.11) in the vicinity of the receiving unit (9.1, 9.2, 9.3) from the identifiable radio signals that can be assigned to these devices (4.1-4.11) and to the respective device (4.1-4.11);b. Determining the position of the receiving unit (9.1, 9.2, 9.3) by the positioning module;c. Determining devices (4.1-4.11) located in the vicinity of the receiving unit (9.1, 9.2, 9.3) from the database on the basis of the determined position of the receiving unit (9.1, 9.2, 9.3);d. Determining the deactive devices (4.1-4.11) in the vicinity of the receiving unit (9.1, 9.2, 9.3) by matching the determined active devices (4.1-4.11) with the determined located in the vicinity of the receiving unit (9.1, 9.2, 9.3) devices ( 4.1-4.11); ande. Limiting the fault in the distribution network by evaluating the position information of the determined active and deactivated devices (4.1-4.11). The arrangement according to the invention is designed to carry out this method.
