Abstract
U/t krivulje, integracijski i fizikalni modeli mogu se koristiti za simuliranje preskoka na izolatorskom lancu. Koriste se konstante koje preporučuje CIGRE, a one ovise o polaritetu primijenjenog napona, duljini razmaka između iskrišta i tipu izolatorskog lanca. U ovom radu, razvijeni su integracijski i fizikalni modeli u EMTP-u pa korišteni za simulacije greške štićenja i povratnog preskoka u 110, 220 i 400 kV prijenosnim mrežama. S fizikalnim modelima su minimalne struje pri kojima se javlja preskok i vremena preskoka niža, dok se integracijski modeli ne mogu koristiti za nestandardne valne oblike prenapona zbog velikih grešaka.
Abstract (english)
U/t curves, integration and leader progression models can be used to simulate flashover on the insulator string. Used constants are recommended by CIGRE and depend on the polarity of the applied voltage, the air gap length and the type of insulator string. In this paper, integration and physical models were developed in the EMTP and applied to shielding failure and backflashover simulations in 110, 220 and 400 kV transmission networks. Physical models lead to lower values of the minimum critical current leading to a flashover and time to flashover. Integration methods cannot be used for non-standard overvoltage waveforms due to large errors.
