| Abstract: | According to the structure of UHV transmission line and operation characteristics, the RTDS model of 750 kV UHV transmission line is constructed and simulated. Based on the simulation, the electrical feature of 750 kV transmission system and the influence on phase segregated current different protection of the capacitance current, harmonic component, aperiodic component are analyzed and emphasized respectively. The solutions are introduced. RTDS simulation shows that diferential protection can meet the especial demands of 750 kV UHV transmission line system. Overall configuration and implementation scheme of fiber optical current differ- ent protection are proposed. |
