Abstract

This document deals with usage of sampled values for protection functions in medium voltage networks. IEC 61850-9-2 brings solution to distribution of current and voltage values measured by sensors. Sampled values could be used for various protection functions. One of the most extensively used type of protection is overcurrent protection relay. If settings of parameters are set wrong in overcurrent protection it can lead to big catastrophe. In this document there is described overcurrent protection relay model which is programmed in LabVIEW and it is the first part of programming a central protection relay model.
