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

Stability of Synchronous Motors Under Single Phase Grid Short Circuits
2018 International Multi-Conference on Industrial Engineering and Modern Technologies (FarEastCon), 2018This paper studies asymmetrical voltage sags caused by single phase short circuits appearing in power grids. Research defines the worst case fault conditions and shows their impact on stability of high voltage synchronous motors. Calculations done within the research take into account the distribution of voltage and current symmetrical components in ...

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.

2006 12th Biennial IEEE Conference on Electromagnetic Field Computation, 2006
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.
