Probabilistic Analysis on the Characteristics of Short Circuit in Single-phase Grounding Fault
2019 IEEE Sustainable Power and Energy Conference (iSPEC), 2019In combination with short circuit simulation and wavelet packet theory, the corresponding probabilistic analysis on the characteristics of single-phase grounding faults of distribution network under stochastic context is studied in this paper. There are two pieces of major research works: firstly, the Latin hypercube sampling (LHS) method is adopted to

Two-Step Optimization for Limiting Three-Phase and Single-Phase Short Circuit Current
2018 2nd IEEE Conference on Energy Internet and Energy System Integration (EI2), 2018With the continuously increasing capacity of modern power system, the problem of excessive short circuit current is becoming more and more severe. Not only three-phase short circuit current (TSCC), but also single-phase short circuit current (SSCC) has exceeded the upper limit.

An Improved Method of Incorporating Mutual Couplings in Single-Phase Short-Circuit Calculations
IEEE Transactions on Power Apparatus and Systems, 1970A method of including mutual couplings in the zero- sequence Z matrix described by Riaz [1] has been adapted for use in single-phase-to-ground short-circuit studies of large power systems. The algorithm of this extension is detailed, and the computational advantages over earlier methods [2]?[4] are pointed out.

Short circuit fault diagnosis in switches of a single-phase full-bridge inverter
2013 Brazilian Power Electronics Conference, 2013This paper presents a method of short circuit fault diagnosis in switches of a single-phase full-bridge inverter, which feeds an inductive load. To diagnose failures, a current limiter and measurements of the variables were used: control voltages, currents in switches and the load current.

FE-Based Modeling of Single-Phase Distribution Transformers With Winding Short Circuit Faults
IEEE Transactions on Magnetics, 2007This paper presents a fast and accurate phase variable model of single-phase distribution transformers with internal winding short circuit faults. The flux linkages of windings (including the winding formed with the shorted winding turns) are used as the phase variables.

Digital diagnosis of short-circuit failures and reconfiguration of a single-phase VSI
2017 IEEE Southern Power Electronics Conference (SPEC), 2017This paper presents a short circuit (SC) fault diagnosis (FD) method for switches of a single-phase voltage source inverter (VSI) with fault-tolerant topology. From the diagnostic variables, the diagnostic rules are established through a digital procedure, and, consequently, the diagnostic method is performed with digital logic circuits.

Probabilistic Short Circuit Analysis on Zero-sequence Current in Single-phase Grounding Faults
2019 IEEE 3rd International Electrical and Energy Conference (CIEEC), 2019In this paper, based on probability modeling, Monte Carlo simulation is adopted to conduct the probabilistic short circuit analysis on the single-phase grounding faults of distribution network. Firstly, a distribution network with four feeders and a photovoltaic (PV) generation is built in Matlab/ Simulink.

Short-Circuit Fault Diagnosis Based on Rough Sets Theory for a Single-Phase Inverter
IEEE Transactions on Power Electronics, 2019The short-circuit (SC) fault diagnosis in inverters is an important procedure for the continuity of the performance and the extension of its useful life. The methods of diagnosis of SC failures produce good results, however, they present unfavorable aspects: they detect only one of the faults of SC, that is to say, the hard switch fault (HSF) or the ...
