Electric power systems transient stability analysis by neural networks
(1995-12-01)
This work aims to investigate the use of artificial neural networks in the analysis of the transient stability of Electric Power Systems (determination of critical clearing time for short-circuit faults type with electric ...
A Model-Based Strategy for Interturn Short-Circuit Fault Diagnosis in PMSM
(Institute of Electrical and Electronics Engineers, 2017-09)
A model-based method for interturn short-circuit fault detection and isolation in permanent magnet synchronous machines (PMSMs) is proposed in this paper. The fault detection is realized based on a residual current vector ...
Second-order model for remote and close-up short-circuit faults currents on DC traction supply
(INST ENGINEERING TECHNOLOGY-IET, 2008)
A technique to calculate the current waveform for both close-up and remote short-circuit faults on DC supplied railways and subways is presented. Exact DC short-circuit current calculation is best performed by sophisticated ...
Estudo teórico de ensaio de tensão em curto-circuito em transformadores de 750kVA – 15kV
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilTecnologia em Automação IndustrialUTFPR, 2015-06-25)
This work aims at submitting to a voltage transformer three-phase short circuit, and in so doing increases the tension gradually up to the rated current. Therefore, this test simulates transformer at full load. Since the ...
Interturn short-circuit fault diagnosis in PMSM with partitioned stator windings
(Institution of Engineering and Technology, 2020-12)
A new signal-based strategy for stator winding interturn short-circuit fault detection and isolation in permanent magnet synchronous machines (PMSM) is proposed. The strategy is based on an analysis of the midpoint voltage ...
Investigating effects of neutral wire and grounding in distribution systems with faults
(2004-12-01)
In some applications like fault analysis, fault location, power quality studies, safety analysis, loss analysis, etc., knowing the neutral wire and ground currents and voltages could be of particular interest. In order to ...
