Abstract

Abstract: Researches on grounding line fault protection have not been comprehensive enough up to now. Fault discrimination cannot be fast and reliable and the fault distance cannot be accurately measured. As a result, the requirements of system transient stability are difficult to be satisfied. A HVDC transmission system model is established in this paper by using the PSCAD/EMTDC simulation platform and a simulation is carried out on the grounding line faults that may occur in HVDC transmission system. The characteristics of the grounding line faults are analyzed and the fault location of single ended traveling waves is measured. The simulation results are consistent with theoretical analysis, which proves the practicality of the built model.

Key words: high voltage direct currant (HVDC) transmission, grounding line, model, fault simulation
