Severity Estimation of Interturn Short Circuit Fault for PMSM

IEEE Transactions on Industrial Electronics, 2019
This paper presents a novel method to estimate the number of shorted turns in a permanent magnet synchronous machine (PMSM) following the detection of interturn short-circuit (ITSC) fault and its location. In this proposed method, PMSM is excited through a low sinusoidal voltage at standstill condition to obtain the winding resistance and synchronous ...

Detection of Interturn Short-Circuit Fault for PMSM With Simple Fault Indicator

IEEE Transactions on Energy Conversion, 2016
Interturn short-circuit fault is a kind of initial failure of the permanent magnet synchronous motor (PMSM) and serious consequences may be caused if it is left undetected. In this letter, a simple fault indicator is defined as the sum of the absolute values of amplitude differences between the stator currents, where the amplitudes of fundamental ...

Short-circuit fault analysis on microgrid

2015 International Conference on Renewable Energy Research and Applications (ICRERA), 2015
This paper presents, a fault simulation on a microgrid consisting of a wind turbine, a solar panel and fuel cell. The power produced by different sources is combined on the same DC bus and converted to AC form using a three phase inverter in order to transfer it to 3-phase AC load. The system takes some precautions against some undesired situations. In

Locating short-circuit faults in underground networks

2011 IEEE Industry Applications Society Annual Meeting, 2011
In power distribution networks, impedance short-circuit faults are hard to detect in their incipient stage, as the fault currents may not be large enough to trip circuit breakers. In this paper, we summarize our research activities in short-circuit fault localization in underground power distribution networks. First, a simulation testbed was built.

On the Numerical Complexity of Short-Circuit Faults in Logic Networks

IEEE Transactions on Computers, 1985
The problem of estimating the number of all possible multiple short circuit faults in a network with a given number of lines is settled in this correspondence. A new combinatorial number, namely an associated Bell number B'(r), which enumerates the number of possible partitions of a set \(\{\) 1,2,\(\cdot \cdot \cdot,r\}\) with certain constraints, is ...
