Currently, theoretical analysis of single‐phase grounding (SPG) faults in low‐current grounding systems has reached a high level of refinement, and the corresponding detection methods have matured. However, there is a significant lack of research on successive grounding (SG) faults, particularly in the area of detecting cross‐line same‐phase successive grounding (CSSG) faults in arc suppression coil grounding systems. To address these issues, a novel faulty line detection method based on transient characteristics of CSSG is proposed. Firstly, a transient equivalent circuit is established, and the characteristics of transient zero‐sequence current (ZSC) are theoretically analysed. Secondly, variational mode decomposition (VMD) is employed to extract low and high‐frequency information from intrinsic mode functions (IMFs). Subsequently, a fault initiation criterion based on kurtosis theory and the Teager‐Kaiser energy operator (TKEO) is proposed, which can accurately detect the occurrence time of secondary faults. Finally, a method for faulty line detection based on cross‐correlation distance (CCD) and transient energy (TE) is proposed. The results of PSCAD simulation under different conditions and field test affirm the accuracy of the analysis and the effectiveness of the proposed method.

“…It is worth mentioning that all kinds of faults have a direct effect on the power system generation, hence the smart grid has been proposed to give a good solution for the system under faults, in addition, the system has a good dynamic response under the dynamic change of the system wither was a fault or load change. A lot of electrical systems have been studied based on different faults [10], [11], [12], [13], [14]. In [10] effective algorithms have been presented to locate the fault for the two-parallel transmission line.…”

“…In [10] effective algorithms have been presented to locate the fault for the two-parallel transmission line. In [11] the behavior of the system voltage and load currents have been studied based on different faults with linear and non-linear loads, in [12] a novel method of the single-phase-to-ground fault has been presented. In [13] double line to the ground has been applied, in addition, Fault resistance values are determined, In [14] the tripping of the line without fault has been discussed and this tripping is more dangerous than a three-phase permanent ground fault, the criterion used in this previous study showed that the inertia time constants, transfer impedance angle and initial relative phase angle between two machines are the important items to determine any machines most effected by fault.…”

The smart grid system is an ideal solution to overcome the limitations of traditional grid systems. A system is considered smart if it has smart in all its parts such as smart generation, smart transmission and distribution, smart control, smart metering, and . . . etc. In this paper, smart transmission and distribution have been presented to achieve the requirements of the smart grid system. By transferring to the smart grid, all utilities catch a lot of benefits such as increasing reliability, efficiency, and safety. On other hand, the operation cost will be decreased. In addition, fast dynamic response for fault detection and isolation based on automatic Internet of Things (IoT) and wireless control can be achieved. It should be noted that in the smart grids, the security of the system and occupational safety will be greatly increased. The system has been validated under different kinds of faults such as single-line to ground fault, and double-line to ground fault. In addition, the theoretical operation has been tested via MATLAB Simulink software.INDEX TERMS PV, wind, smart grid system, smart transmission and distribution system, controllable crowbar, fault.
