The Use of Symmetrical Components in Electrical Protection
Conference for Protective Relay Engineers, 2019In some situations, the symmetrical components of voltage and current are more sensitive to electric faults compared to their phase-domain counterparts.

Estimation of Voltage Symmetrical Components and Current Harmonics Using Multi-Output Kalman Filter
2019 Advances in Science and Engineering Technology International Conferences (ASET), 2019This paper presents an improved application of Kalman Filter (KF) for estimating both symmetrical components of unbalanced voltage and current harmonics at the same time. In the proposed method, multi-output KF is developed instead of conventional single-

Six-terminal symmetrical-component networks
Proceedings of the Institution of Electrical Engineers, 1967The paper deals with the analysis of a general 3-phase 6-terminal network suitable for providing at its output the positive- or negative-sequence component of the input voltages. Criteria are produced for the operation of the network. Conformal maps are included showing (a) the influence of the network components on the output voltage of the unloaded ...

Topological considerations on the symmetrical components transformation
IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 2000This paper presents the well-known symmetrical components transformation (SCT) by means of a different approach from the traditional matrix analysis: a topological lecture provides, in fact, the results obtained by the existing analysis in a more suitable form for network applications.

Effect of Harmonics on Symmetrical Components of Power Network Using Least Square Method
2018 2nd IEEE Conference on Energy Internet and Energy System Integration (EI2), 2018This research work estimates the effect of harmonics on symmetrical components of power network using least square method. Symmetrical component analysis of power line faults has been considered an effective tool for the design and control of power ...

Symmetrical Component Adaptive Beamforming
The Journal of the Acoustical Society of America, 1968The theory of symmetrical components, long used in connection with fault-current analyses of multiphase power-distribution systems, has been applied to the problem of adaptive beamforming with the result that the response of a spatially diverse array of sensors can be made virtually free of the effects of the stationary part of the surrounding noise ...

Processing of Symmetrical Components in Time-Domain
IEEE Transactions on Power Systems, 2007A novel system for decomposing a set of three-phase signals into its constituting symmetrical components is proposed. The system also estimates the frequency, the magnitudes and phase-angles of the sequence components. The system is useful for online estimation of instantaneous symmetrical components and their attributes in the presence of frequency ...

Metering of symmetrical components
Electrical Engineering, 1932CONTENTS of previous publications on metering of symmetrical components have been confined to the components of current and voltage in 3-phase 3-wire systems. This paper discusses the method of metering the positive and negative sequence power and energy in 3-phase 3-wire systems, and positive, negative, and zero sequence power and energy in 3-phase 4 ...
