Analysis of Transient Regimes for Single-Phase Short Circuits in Electrical Lines with Isolated and Compensated Neutral

2020 2nd International Conference on Control Systems, Mathematical Modeling, Automation and Energy Efficiency (SUMMA), 2020
This research paper describes the modeling and analysis of operating regimes of distribution electrical lines with isolated and compensated neutral for single-phase earth faults. The results of the work allow us to form standards based on several parameters characteristic of this regime, which can be used to identify the abnormal mode and creates ...

Single-Phase Short-Circuit Testing of Vacuum Interrupters for Power Systems with an Effectively Earthed Neutral [PDF]

2018 28th International Symposium on Discharges and Electrical Insulation in Vacuum (ISDEIV), 2018
Circuit breakers using vacuum interrupters (VI) are frequently tested according to the IEC standard 62271–100 and the IEEE standard C37.09. The IEC 62271–100 standard was updated to include additional tests for medium voltage circuit breakers, designed to verify successful interruption in electrical power systems with an effectively earthed neutral ...

Fault-Tolerant Control for Single-Phase Open-Circuit and Short-Circuit Fault in Five-Phase PMSM With Third-Order Harmonic Back EMF Using Coefficients Reconfiguration

IEEE transactions on energy conversion
For a five-phase permanent magnet synchronous machine (PMSM), the third-order harmonic back EMF is increased by changing the shape of the permanent magnet for increasing average torque in healthy operation.

Analysis of Single-phase Short-circuit Current Suppression Measures at Converter Stations and Their Effects on Power System Reliability

2019 IEEE Asia Power and Energy Engineering Conference (APEEC), 2019
Aiming at the issue that the single-phase short-circuit current at the 500kV side of Yibin and Fulong converter stations has exceeded the breaking capacity of breaker, the reason is analyzed and the measures are put forward to reduce the single-phase ...

Protection of overhead lines with voltage of 380 V from the single-phase short circuits

2016 2nd International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM), 2016
The article deals with the issue of increasing the efficiency of the fuses in 380 V electrical networks with TN-C system with single-phase short circuits on the PEN conductor. The problem essence and scale are described briefly. To bring the protection in compliance with new regulatory requirements, partitioning the low voltage distribution network is ...

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.

Probabilistic Short Circuit Analysis on Zero-sequence Current in Single-phase Grounding Faults

2019 IEEE 3rd International Electrical and Energy Conference (CIEEC), 2019
In this paper, based on probability modeling, Monte Carlo simulation is adopted to conduct the probabilistic short circuit analysis on the single-phase grounding faults of distribution network. Firstly, a distribution network with four feeders and a photovoltaic (PV) generation is built in Matlab/ Simulink.

An analytical model of a single phase DQ-controlled inverter for power system short circuit calculations

2016 North American Power Symposium (NAPS), 2016
The short-circuit contribution of Inverter interfaced systems is determined by the control architecture, generally limited to 110%–150% of rated current and is generally not sustained past a cycle or two. IEEE1574 compliant inverters with anti-islanding may trip without contributing to a fault.
