Abstract

V diplomskem delu obravnavamo problematiko koordinacije nadtokovne zaščite, pri čemer je glavni cilj izboljšati selektivnost v obstoječem nizkonapetostnem omrežju. V skladu s podano topologijo omrežja z uporabo programskega orodja SIMARIS Design izdelamo enopolno shemo in koordinirano nastavimo uporabljene nadtokovne sprožnike Siemensovih odklopnikov. Zaradi neustrezno izbrane opreme ni možno zagotoviti popolne selektivnosti, je pa le-ta dosežena v večjem delu omrežja. Za doseganje selektivnosti v celotnem omrežju predlagamo uporabo modulov, ki omogočajo signalno povezovanje.

Secondary title: Coordination of low voltage over-current protection using simaris design programming tool
Secondary abstract: The diploma work discusses the problem of coordination of overcurrent protection, where the main goal is to improve the selectivity in the existing low-voltage network. Using the SIMARIS Design software tool a single-pole scheme is created according to the given network topology. Furthermore, coordinated settings of overcurrent triggers for Siemens circuit breakers is also performed. A complete selectivity is impossible to ensure due to the unsuitable equipment, however in the main part of the network the selectivity was achieved. In order to ensure selectivity in the entire network we propose usage of communication modules for zone selective interlocking.
