Abstract ：
Existing single-phase ground fault mitigation device (SPGFMD) is usually equipped with a grounding terminal, but the resistance of the grounding grid may change during the long-term operation of the power system. To analyze the influence of the grounding grid resistance on the effectiveness of ground fault current mitigation, the relationship between the grounding grid resistance and the residual ground fault current is derived. This article conducts simulation and experiment to investigate the impact of various grounding grid resistances on the suppression effect of ground fault current under different ground transition resistance circumstances. The critical grounding grid resistance that affects the single-phase ground fault current mitigation effect has been identified, offering a theoretical foundation for the on-site evaluation of the grounding grid status of SPGFMD. The influence mechanism of grounding grid resistance is verified by the simulation and experiment results. The results indicate that the SPGFMD with current-based method can withstand a certain range of grounding grid resistance variation under the condition of a single-phase ground fault in the distribution networks. However, the effectiveness of ground fault current mitigation deteriorates when the grounding grid resistance exceeds the critical threshold. © 2025 John Wiley & Sons Ltd.

Abstract ：
The traditional phase-segregated arc suppression (AS) methods often neglect the influence of line voltage drop (LVD), resulting in the problem of large residual current when single-line-to-ground (SLG) faults occur at the end of heavily loaded lines, making reliable AS difficult. To effectively suppress fault currents during medium and low impedance SLG faults at the end of heavily loaded lines, the phase-segregated AS method considering LVD is proposed in this paper. Additionally, the phase-segregated AS method, which is based on sliding mode control using an exponential convergence rate, is utilized to reduce the total harmonics distortion of fault current and neutral point voltage after current injection. The simulation results validate the effectiveness of the proposed method under the case of the medium or low impedance ground fault occurring at the end of heavily loaded lines.

Abstract ：
Since the effectiveness of the flexible current arc suppression method heavily relies on the accurate measurement of the distribution line-to-ground parameters, the suppression of single line-to-ground (SLG) fault current may deteriorate due to factors such as line switching and other disturbances during SLG fault arc suppression. Additionally, during SLG fault arc suppression, promptly identifying the fault type and rapidly deactivating the flexible arc suppression device (FASD) can reduce the overvoltage risk in non-faulted phase devices. To address these issues, this paper presents a parameter identification method based on recursive least squares (RLS) while a variable forgetting factor strategy is introduces to enhance the RLS algorithm's disturbance rejection capability. Simulations verify that the variable forgetting factor recursive least squares (VFF-RLS) algorithm can accurately identify distribution line-to-ground parameters in real time and effectively suppress SLG fault current. The online identification of grounding transition conductance is simultaneously used to determine the fault type and quickly detect when the SLG fault has been cleared.

Abstract ：
Two cascaded H-bridge converters (CHBC) are proposed to regulate the zero-sequence reactive current of distribution networks flexibly to realize the online ice-melting of ice-covered lines without power outages. The two CHBCs are connected in series to the grounding transformer at the head and end of the ice-covered lines. The zero-sequence voltage of the distribution networks is regulated by the end CHBC within the permissible range of insulation, and the resulting zero-sequence capacitive current to ground flows through the three-phase ice-covered conductors as ice-melting current, which realizes a better effect than the single-phase short-circuit current ice-melting. By regulating the capacitance current to the ground of the distribution networks through the head CHBC, the size of the ice-melting current can be adjusted arbitrarily. The proposed method does not require a single-phase grounding short circuit and can simultaneously accurately regulate the ice-melting current to melt ice in three-phase lines. CHBCs only have reactive interaction with the distribution networks, saving the capacity of DC sources, and the sum of power interactions is zero, which does not affect the normal supply voltage of the distribution networks, and there is no need for power outages for the entire network loads. The simulation and experimental results verify the feasibility and effectiveness of the proposed method and control scheme. © 2024 Power System Technology Press. All rights reserved.

Abstract ：
There is a problem in that the non-fault phase bridge arm of traditional three-phase direct-hanging flexible arc suppression device bears the line voltage. Thus a fault phase bridge arm transfer grounding arc suppression method is proposed. This method controls the fault phase bridge arm transfer grounding through the switch. The bus voltage is shared by the fault phase bridge arm and the non-fault phase bridge arm, and the three-phase bridge arm outputs the current to achieve arc suppression. The cascaded H-bridge DC-link needs an independent power supply, so a distributed voltage balance commutation modulation method is proposed. The modulation method selectively changes the H-bridge output state according to the influence of H-bridge output state and current direction on the charge and discharge of the DC-link capacitor, and then realizes the stability of DC-link voltage. The arc suppression device using this modulation method does not need to be equipped with an independent power supply on the DC side, and can maintain H-bridge DC-link voltage stability during the arc suppression process. Finally, the proposed method is verified by Matlab/Simulink simulation software, and the results prove the effectiveness of the proposed method. © 2024 Power System Protection and Control Press.

Abstract ：
Most of the phase-to-ground parameters induced between distribution lines and ground are asymmetric, which can result in the generation of unbalanced voltage, shifting the neutral point voltage. For compensated distribution networks, the existence of an arc suppression coil can increase the influence of asymmetric parameters and exacerbate the deviation of neutral point voltage. Maintaining the balance of three-phase voltage is a prerequisite not only for the stable operation of the distribution networks but also for improving the reliability of single-phase ground fault detection. This article proposes a novel online split-phase identification of asymmetric parameters between distribution lines and ground for unbalanced voltage compensation based on power electronics. First, an adaptive active current-type compensation method based on power electronics is proposed; it can adapt to compensate for three-phase unbalanced voltage with different neutral point grounding styles. Second, particle swarm optimization is used to realize the online split-phase identification of the phase-to-ground parameters of the distribution power lines. The identified parameters are used to calculate the reference value of the compensation current and the asymmetry of each phase-to-ground parameter. Finally, the feasibility and effectiveness of the proposed method are verified by simulation and experiment.

Abstract ：
To address the existing issue of electric shock incidents that cannot be accurately identified by current leakage protection devices, this paper presents a novel electric shock accident recognition method. Firstly, the method of singular spectrum analysis (SSA) is employed to extract the main components of leakage recording data. Subsequently, 20 temporal domain features of the leakage current waveform are extracted. Then, an ensemble learning model based on extreme gradient boosting (XGBoost), categorical boosting (CatBoost) and random forest (RF), is established to select optimal features that best represent the sample characteristics from the feature set. Finally, support vector machine (SVM) is used to classify the extracted dataset. Experimental results demonstrate that this method can rapidly differentiate between electric shock faults and common leakage faults, achieving an accuracy rate as high as 99%, indicating its feasibility. © 2024 IEEE.

Firstly, the topology and working principle of the device are analyzed. And a compensation current distribution method of the bridge arm is proposed. Secondly, a double-loop passivity-based controller is designed. Finally, the proposed method is verified by MATLAB/Simulink software and 10 kV physical simulation system of distribution network. The comparisons between doubleloop passivity-based control, passivity-based control, and proportional integration control is discussed. The result shows that the proposed method can accurately and rapidly compensate the fault current.
