| Abstract: | The specialties in applications of ohm relays, bowl relays, polygon relays, and positive and negative sequence component relays to extra high voltage cable lines are analyzed, as well as problems that may occur. The relevant simulation calculation and verification are conducted, and the merits and demerits of these phase-to-phase distance protections applied to extra high voltage cables are compared. Improvement for simulation is put forward, and the influence of the electric parameters' characteristics of the extra high voltage cables on the phase-to-phase distance protections are analyzed combining theories and simulation results. |
