An Improved Method of Incorporating Mutual Couplings in Single-Phase Short-Circuit Calculations

IEEE Transactions on Power Apparatus and Systems, 1970
A 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, 2013
This 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.

Study of Gray Code Implementation for Single Phase Inverter Short Circuit Protection

2018 International Conference on Sustainable Energy Engineering and Application (ICSEEA), 2018
Inan electronic circuit, short circuit protection can be done by using passive and active method. The active method is usually using current sensor and/or thermo sensor while the passive method is using trigger design for power circuit such dead time delay trigger or digitally interlock trigger for high side and low side.

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), 2018
With 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.

Short-Circuit Fault Diagnosis Based on Rough Sets Theory for a Single-Phase Inverter

IEEE Transactions on Power Electronics, 2019
The 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 ...

FE-Based Modeling of Single-Phase Distribution Transformers With Winding Short Circuit Faults

IEEE Transactions on Magnetics, 2007
This 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.

Modeling of short-circuit transients at terminals of a single-phase self-excited induction generator

2017 18th International Symposium on Electromagnetic Fields in Mechatronics, Electrical and Electronic Engineering (ISEF) Book of Abstracts, 2017
In the paper, sudden short-circuit transients at terminals of an autonomous single-phase induction generator were simulated using field-circuit 2D model of the single-phase induction generator. The transients at terminals were calculated for different configurations of capacitors in stator windings.
