Abstract

When a fault occurs on a transmission line, fault generated high frequency transient components are a series of natural frequencies in frequency domain. This paper proposes a protection algorithm for MMC-HVDC transmission line based on spectrum characteristic of natural frequency. Spectrum correlation coefficient is used to determine whether a fault is internal or external fault. The scheme performance was proven using PSCAD/EMTDC simulations in ±500kV MMC-HVDC power system. The simulation results show that it can identify fault quickly and accurately.
