Single-phase short-circuit torque of a synchronous machine
Electrical Engineering, 1932 This paper extends the analysis of synchronous machines previously published by Doherty and Nickle 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. The effect of amortisseur windings is

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.

Research of the possibility for limiting the currents of a single-phase short circuit in HV networks [PDF]
2020 12th Electrical Engineering Faculty Conference (BulEF), 2020 This article discusses the possibility of reducing the levels of single-phase short circuits in HV networks. Since over 80% of all short circuits are single-phase. The dimensional condition for the equipment in the HV switchgears is a three-phase short circuit, as a result of which the currents of single-phase short circuits are inadmissible to be ...

Two-Step Optimization for Limiting Three-Phase and Single-Phase Short Circuit Current [PDF]
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.

Influence of single-phase short circuit to TWACS signal
2013 International Conference on Quality, Reliability, Risk, Maintenance, and Safety Engineering (QR2MSE), 2013Previous TWACS models are proposed for no electric power system fault conditions and don't involve the transmission of power system under fault condition. This paper studies the running state and signal detection of TWACS under the condition of single-phase short circuit condition in neutral point ineffectively grounded power system.
