Abstract
The analysis of high voltage coal-mine distribution networks has been carried out to build up the equivalent circuit in order to study the ground fault processes under different conditions. The current distribution-based evaluation of protective relay functionality has revealed a strong impact of the network topology, length of cables, continuous variation in the network parameters on the efficiency of protective relays. The increase in the distributions network reliability can by achieved through involving the information exchange between the network nodes in the process of relay decision making.
