Effects of Neutral Point Grounding Methods on Single-Phase Short Circuit Fault Characteristics

2022 21st International Symposium INFOTEH-JAHORINA (INFOTEH), 2022
Short circuit faults are one of the most common disturbances in power systems that occur because of insulation failure due to a sudden overvoltage condition caused by lightning, switching operations, insulation contamination, etc.

Influence of Rotor Damping Bars on Rotor Temperature Rise of Synchronous Condenser after Single-Phase Short-Circuit Fault

Annual Meeting of the IEEE Industry Applications Society, 2022
The main function of a synchronous condenser (SC) is to provide continuous and transient reactive power for the Ultra High Voltage Direct Current (UHVDC) converter station or the new energy power grid.

Single-phase short-circuit torque [PDF]

Electrical Engineering, 1932
The analysis of synchronous machines previously published by Doherty and Nickle is expanded in this article to include the calculation of torque due to single-phase short-circuit. The torque is expressed as the sum of odd and even harmonic series which are simply related to those previously derived for the armature current.

Digital diagnosis of short-circuit failures and reconfiguration of a single-phase VSI [PDF]

2017 IEEE Southern Power Electronics Conference (SPEC), 2017
This 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.

Neutral Voltage Modeling and Its Remediation for Five-Phase PMSMs Under Single-Phase Short-Circuit Fault Tolerant Control

IEEE Transactions on Transportation Electrification, 2022
Field-oriented control (FOC) still serves as an advanced way to control ac motors for industrial applications, as such, this technique is being expanded to the postfault operation of five-phase permanent magnet synchronous motors ( $5\Phi $ -PMSMs) under

Research on Short-Circuit Force of Distribution Transformer Based on Short-Circuit Test by Single-Phase Power and Three-phase Power

2021 3rd Asia Energy and Electrical Engineering Symposium (AEEES), 2021
Distribution transformer is one of the important electrical equipment in power grid. The working state of distribution transformer directly affects the safe and stable operation of power grid. When distribution transformer during short circuit, the short-circuit force will cause distribution transformer damage.

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

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.
