Electromagnetic Disturbances at 380 kV Power Systems Operations due to Unloaded Line Switching
Abstract
In this paper, the electromagnetic disturbances at 380 kV power system operations which appear at the unloaded line switching are evaluated. The paper presents the modelling and simulation of an unloaded three-phase line switching effect in a Power System, using the PSCAD and MathCAD software packages. The transient recovery voltages (TRV) and overcurrents (OC) in the 380 kV network and the electrical field (EF) were obtained, according with overvoltages (OV) at 380 kV. After that, a comparative analysis of results is made. The paper presents the electrical field values according to modelled and simulated disturbances. The simulation was performed using the EMTDC/PSCAD software package, in order to obtain the electromagnetic disturbances in the transmission line and busbars. The proposed simulation is applied for an unloaded transmission line connected between KEPEZ and YATAGAN in the 380 kV Turkish National Power Transmission Systems. Also, the paper presents modelling, simulations, measurements and experiments performed for the determination of switching overvoltages for 400 kV unloaded line switching in a Romanian Network (Tintareni-Sibiu). After that, a comparative analysis of results regarding switching overvoltages determined through modelling and experiments is made and conclusions about admissible limits recommended by the CIGRE and IEEE international norms are established.
