The Master Thesis deals with a proposal of algorithm of a protective function for assymetric faults location in resistance-grounded medium voltage networks with decentralized measurement of instantaneous voltage and current values. The theoretical part describes a single pole fault in the resistance-grounded network including the network analysis using the symmetric component method. Furtherly follows brief reserse of nowadays considered possibilities of faults location in the medium voltage networks. The proposed algorithm which works on the principle of negative sequence changes and change differencies of voltage and current is described by mathematical operations and flowchart, and it is furtherly tested in the PSCAD simulator on the proposed network model. Also the algorithm is tested in the Matlab program using the real data from the local distribution network Pod Palackeho vrchem where the initial pilot implementation is assumed. The last part of the thesis includes also the algorithm sensitivity analysis.
