Sažetak
This paper presents results of time-domain simulation of single-phase opening (the effect of the 110 kV phase conductor rupture) of the 110 kV transmission line Komolac - Trebinje (a part of radial connection of HPP Dubrovnik to the system) in realistic operating conditions. The simulation results comprise instantaneous and RMS values of phase currents, phase voltages and residual current in the 110 kV line bay Komolac at the HPP Dubrovnik switchyard and in the 110 kV transmission line bay Trebinje at the substation Komolac. Simulation results are compared with quantities recorded by the numerical line protection device REL511 installed at HPP Dubrovnik. Simulation includes electromechanical transients with excitation system and turbine governor being modelled. Rather good correspondence between simulation results and measurements in this particular case shows that such calculation results could be used as a basis for tuning and coordination of protection systems
