“…The fault location results in Table IX are correct, which indicates that the proposed scheme can detect faulty line section effectively in radiation network including several feeders. In order to present the reliability advantage of faulty line section identification method with strong noise background, we compared this method with three methods introduced in [12], [36] and [16], which have been verified in distribution network and are denoted as Method A, B and C, respectively.…”

“…The location results for Method C in different conditions are shown in Table XII using the field data in Table IX. Because the data processing method of Method A is not mentioned in [16], the results show that Method C can detect the faulty feeder if the grounding resistance is 0 Ω but it doesn't work properly sometime, especially when the grounding resistance is bigger than 200 Ω. The noise in the actual distribution grid is very strong, resulting in incorrect location results if the grounding resistance is large.…”

“…However, it is difficult to detect the faulty feeder when the voltage inception angle is near zero. The correlation analysis of the transient zero-sequence current waveform between the faulty and the healthy feeder was used for faulty feeder identification in [15]- [16]. The transient component of the zero-sequence current and voltage was used for calculating the transient energy of every feeder in [17], which may be affected by the noise and lead to mis-judgement when the fault resistance is high.…”

As a result of small fault current, high level of noise and a large penetration of distributed generators (DG), in the neutral non-effectively grounded medium-voltage (MV) distribution networks, it is quite difficult to locate the faulted line section for single phase to ground faults. In this paper, using a technique based on synchronized measurements in distribution networks, a fault location method based on the analysis of the energy of the transient zero-sequence current in the selected frequency band (SFB) is proposed. The equivalent impedance of the distribution network with lateral branches is studied with an equivalent network, and the phase-frequency characteristics of the equivalent impedance are analyzed. The SFB, within which the transient energy of the faulty line section is larger than that of the healthy line sections is determined. A combined fault-section location criterion is proposed and the implementation scheme is illustrated with the distribution level phasor measurement units. Numerical simulations of the IEEE 34 node system and the field experiments of a 10kV distribution network validate the feasibility and effectiveness of the proposed method.Index Terms--Active distribution networks, fault location, neutral non-effectively grounded system, single phase to ground faults, transient zero-sequence current.

“…Travelling wave method [1], Hilbert-transform [12], and Wavelet packet transform [13][14][15] adopt magnitude, polarity, or energy of transient zero-sequence current to identify the faulty feeder, respectively. The publication [16] classifies faulty feeder and healthy feeder by means of the similarity principle. The above passive methods are of great value to a certain extent for low impedance faults.…”

The identification of faulty feeder for single-phase high impedance faults (HIFs), especially in resonant grounding distribution system (RGDS), has always been a challenge, and existing faulty feeder identification techniques for HIFs suffer from some drawbacks. For this problem, the fault transient characteristic of single-phase HIF is analyzed and a faulty feeder identification method for HIF is proposed. The analysis shows that the transient zero-sequence current of each feeder is seen as a linear relationship between bus transient zero-sequence voltage and bus transient zero-sequence voltage derivative, and the coefficients are the reciprocal of transition resistance and feeder own capacitance, respectively, in both the over-damping state and the under-damping state. In order to estimate transition resistance and capacitance of each feeder, a least squares algorithm is utilized. The estimated transition resistance of a healthy feeder is infinite theoretically, and is a huge value practically. However, the estimated transition resistance of faulty feeder is approximately equal to actual fault resistance value, and it is far less than the set threshold. According to the above significant difference, the faulty feeder can be identified. The efficiency of the proposed method for the single-phase HIF in RGDS is verified by simulation results and experimental results that are based on RTDS.
