Thermal and Arc Flash Analysis of Electromotor Drives in Distribution networks
The paper presents thermal analysis and arc flash analysis taking care of protection relays coordination settings for electromotor drives connected on electrical network. Power flow analysis is performed to check if are there any voltage and loading violation conditions in the system. Fault analysis is performed to check the values of short circuits and compute arc flash energy dissipated at industrial busbars to eliminate damages to electrical equipment and electrical shocks and hazard for personnel. Computers enable use of smart algorithms useful to electrical engineers how they can provide accurate all of these actions. Fast and accurate procedure for proper incident arc flash energy computation and overcurrent relays coordination in distribution networks is presented. The paper presents the use of Arc Flash module for arc flash energy computation during the short circuit on LV and HV busbars with soft motor starters. A sample case of one real network is presented which use soft motor starters and influence on arc flash energy in one transformer station supplying industrial network in Bosnia and Herzegovina
