Simulation of Short Circuit and Lightning Transients on 110 kV Overhead and Cable Transmission Lines Using ATP-EMTP

This paper presents calculation and simulation of a three phase short circuit, single line to ground fault and lightning stroke transients on a 110 kV cable-overhead transmission line that connects the new 110/20 kV transformer station Djakovo 3 with the existing TS 400/110 kV Ernestinovo and TS 220/110 kV Djakovo. Calculation and simulation of short-circuit transients are made using the EMT DIgSILENT Power Factory module. Simulations of a lightning stroke are compared using the ATP-EMTP software and EMT DIgSILENT module. Using the composite DSL (DIgSILENT Simulation Language) model, the Direct lighting stroke has been represented as the Double-exponential function and the return stroke as the Heidler function. Using the ATP-EMTP model, the lightning stroke has been represented as the Heidler function. Lighting stroke simulations are made with and without the presence of ZnO polymer-housed surge arrester model in both simulation tools
