Positioning Method

Due to the high ground fault resistance and the complexity of power distribution network structure (such as too many nodes, branches and too long lines), adopting common traveling wave method and ac injection method can not effectively locate the single-phase grounding fault in the distribution network system.To solve above problems and determine the position of the point of failure prisely, this paper adopted the dc location method of injecting the dc signal from the point of failure under the power outage offline. This paper introduces the single phase dc method and the method of three phase dc, and the simulation shows that the dc location method is effective and feasible.

The Impact

There exist many single-phase photovoltaic generations in modern power distribution network, and these distributed sources may be in a certain extent affect the symmetry of voltage. To investigate the impact of photovoltaic generation on quality problem of distribution network, mathematical and digital model of photovoltaic power generation are built in this paper, and the maximum power point tracking control is simulated based on incremental conductance method.

Location Methods

Traveling wave (TW)-based fault-location methods have been used to determine single-phase-to-ground fault distance in power-distribution networks. The previous approaches detected the arrival time of the initial traveling wave via single ended or multi-terminal measurements. Regarding the multi-branch effect, this paper utilized the reflected waves to obtain multiple arriving times through single ended measurement. Potential fault sections were estimated by searching for the possible traveling wave propagation paths in accordance with the structure of the distribution network. This approach used the entire propagation of a traveling wave measured at a single end without any prerequisite of synchronization, which is a must in multi-terminal measurements. The uniqueness of the fault section was guaranteed by several independent single-ended measurements. Traveling waves obtained in a real 10 kV distribution network were used to determine the fault section, and the results demonstrate the significant effectiveness of the proposed method.

Novel Method

This paper presents a novel method of fault diagnosis by the use of fuzzy logic and neural network-based techniques for electric power fault detection, classification, and location in a power distribution network. A real network was used as a case study. The ten different types of line faults including single line-to-ground, line-to-line, double line-to-ground, and three-phase faults were investigated. The designed system has 89% accuracy for fault type identification. It also has 93% accuracy for fault location. The results indicate that the proposed technique is effective in detecting, classifying, and locating low impedance faults.

This paper presents a three-winding coupled inductor-based high-gain DC–DC converter fed transformerless dynamic voltage restorer (TDVR) to compensate the voltage sag, voltage swell and interruption in the single-phase power distribution network. The TDVR supported by the cascaded DC–DC boost converters offers high boosting gain. The cascaded connection of DC–DC converters reduces the efficiency due to the usage of more active and passive devices. The proposed PV-TDVR is designed to provide higher efficiency by reducing the number of power conversion stages with reduced numbers of active and passive components. The operating modes of the proposed PV-TDVR are presented in a comprehensive way. The MATrix LABoratory (MATLAB) simulation and 1-kV prototype model results are presented to analyze the performance of PV-TDVR in mitigating the voltage disturbances in the single-phase power distribution network.
