Impacts of Transformer Loading on the Harmonic Distortion Created by GIC Flows

IEEE transactions on industry applications
Geomagnetically induced currents (GICs) are currents dominated by dc components that flow through grounding circuits into power systems. These currents are typically initiated by geomagnetic disturbances, and flow into power systems through power ...

High stability and low harmonic distortion PGC demodulation technique for interferometric optical fiber sensors

Optics and Laser Technology, 2019
Phase generation carrier (PGC) demodulation technique is widely adopted in the field of interferometric optical fiber sensors, for its high sensitivity, good linearity and large dynamic range.

Total Harmonic Distortion Decomposition Depending on Distortion Origin

IEEE Transactions on Power Delivery, 2005
The total harmonic distortion (THD) ratio is a well-known parameter that characterizes the distortion degree at a specific point of the grid. In this paper, a decomposition of the THD will be presented in order to determine the responsibility of the distribution company and the electrical energy consumer for the harmonic distortion measured at the ...

Harmonic distortion and unbalance analysis in multi-inverter photovoltaic systems

International Symposium on Power Electronics, Electrical Drives, Automation and Motion, 2018
The growing penetration of distributed generation connected to the grid by power electronics converters can adversely affect the power quality. The capability of the system to host large harmonic distortions and unbalance in three-phase systems may be an

Ending harmonic distortion

World Pumps, 2009
ABB's Kari O Kovanen looks at methods used to reduce harmonic distortion produced by variable speed drives, including reactors, multi-pulse solutions and passive harmonic filters, and also refutes some of the criticisms of low harmonic drives made by some commentators.

New Harmonic-Distortion-Suppression Method

2011
This section presents a method to improve the linearity of current steering (CS) digital-to-analog converters (DACs). The method uses unary functional segmentation to create redundant D/A functions, defined around nominally identical sub-DAC entities. Further, the method uses a digital pre-processor to create phase shifted replicas of the input signal ...

Distortion: Total harmonic distortion in an asymmetrically clipped sinewave

IEEE Instrumentation & Measurement Magazine, 2011
The application of a signal to an electronic system such as an amplifier invariably results in an output that is, in some sense and to some extent, a distorted version of that input signal. The application to which the system is put is a major determiner of whether or not the distortion can be neglected or, at least, of how much distortion can be ...

Harmonic distortion in SC sigma-delta modulators

IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 1994
The maximum achievable resolution in noise-shaping modulators is a function of three principal parameters: oversampling ratio, M; noise-shaping order, L; and quantizer resolution, N. For practical implementations, thermal noise in MOS switches and amplifiers, bandwidth and slew-rate in integrator circuits in switched-capacitor (SC) implementations, and
