“…Smoothing reactor and dc filters are installed at both terminals of HVDC transmission line with the purpose of filtering the harmonics effectively [8]. They have attenuation to the characteristic harmonics and high frequency harmonics, constituting a line boundary for those components of the transient signals.…”

The line boundary of high voltage direct current (HVDC) system is composed of dc filters and smoothing reactor, which has attenuation to high frequency signals and can be used to propose novel line protections. Analysis on the high frequency attenuation characteristic of line boundary is presented in this paper. Based on the practical parameters and arrangements of dc filters and smoothing reactor, this paper studies the high frequency attenuation characteristic with different types of dc filter, different arrangements of smoothing reactor, and different components parameters. Results show that HVDC line boundary has large attenuation to high frequency signals and prove the high frequency signals can be used to form novel HVDC line protections.

“…This method also needs a high sampling frequency because the fIrst wave-head is required to be detected accurately. Boundary scheme [5][6] is a new approach for HVDC transmission line fault detection, which is based on boundary characteristics of HVDC system. As the high-frequency components of the fault signal are blocked by the smoothing reactor and the fIlter reactor, this method detect the harmonic components of fault signals to distinguish internal fault from external fault.…”

Since the grounding mode, line parameters, and thus the transient performance of MMC-HVDC are quite different from those of LCC-HVDC system and AC system, fault detection strategies used in LCC-HVDC are no longer applicable to MMC-HVDC. In this paper, a wavelet entropy based fault detection approach for MMC-HVDC is proposed to detect DC line faults and distinguish AC area fault. This method does not use the magnitude of the current but evaluate the wavelet entropy of the current signal to detect the fault. Firstly, the factors which affect fault transient performance of MMC-HVDC are analyzed. Then the wavelet entropy theory and its role in the detection of non-stationary signals are outlined. The proposed fault detection mechanism using wavelet energy entropy and wavelet time entropy to process fault current signals is described in detail. Finally, the computer simulations are carried out. The results show that the proposed method can detect the pole to ground fault and the pole to pole fault in MMC-HVDC accurately and can satisfy the time requirement.
