摘要:A novel current differential relay principle based on Marti model is proposed in this paper. Compared with Bergeron model based differential protection, the frequency-dependent characteristic of line parameters is taken into account in the new principle, so that the calculating result is more accurate. Simulating comparison have been carried out between the proposed protective principle and Bergeron model based protection for the first 1000 kV UHVAC transmission line in China. Simulation results show that this novel principle has high reliability for internal and external faults, and can response the earth fault via a high resistance sensibly.
