Abstract:

In this paper two input current modulation strategies for matrix converters are experimentally analyzed under two different supply conditions: sinusoidal unbalanced voltages and non-sinusoidal balanced voltages. Both strategies use the Space Vector Modulation (SVM) technique in order to control the matrix converter accordingly to the input and output constraints. Strategy A modulates the input currents keeping the corresponding space vector in phase with the input voltage vector. Strategy B operates in order to keep the input current vector in phase with the positive sequence fundamental compo

The full-bridge submodule (FBSM)-based modular multilevel converter (FBSM-MMC) offers promising performance due to its ability to output negative FBSM voltage.

The focus of the research is to redistribute the FBSM powers by injecting an additional power degree of freedom, resulting in a smaller FBSM capacitor voltage ripple, while keeping the maximum AC output voltage for a given fundamental frequency component of the arm voltage reference.

Power quality conditions in electrical power networks have drastically changed in recent years.

In the case of the inductive voltage transformer (VT), the resonance phenomenon may be the main reason for its poor transformation accuracy of the non-sinusoidal voltage.

The results are consistent with the values obtained in the reference condition at their nominal primary voltage. T

Abstract:

The operation process of the electric valve drive is accompanied by the generation of higher harmonics — canonical and non-canonical. Limitation of the level of canonical harmonics is carried out by power resonance filters, however, in the case of asymmetry of the control pulses of the thyristors of the converters, non-canonical harmonics are generated — both even and odd harmonics. The composition of non-canonical harmonics can be determined in the case of harmonic analysis of non-sinusoidal current and voltage coefficients. The conducted harmonic analysis makes it possible to determine the c

Abstract:

This article presents a comparative experimental evaluation of some power calculation methods used for three-phase and single-phase systems. In order to make the comparison, methods based on three reference frames, the natural one, αβ and dq, are considered. This paper addresses the experimental comparison for single-phase systems facing sinusoidal and non-sinusoidal waveforms in both linear and non-linear loads. The results are obtained from an experimental platform consisting of a controlled voltage inverter and an acquisition system based on a TMS320F28335, where the power calculation algor

Nonlinear loads draw non sinusoidal current and voltage from the utility.These nonsinusoidal current and voltages created due to nonlinear loads are called harmonics.The harmonic voltages and current disturbs the system back and creates big power quality problem.Therefore in order to mitigate harmonic problems different mechanisms are used.Here as introduction different power quality problems, harmonics and their mitigation techniques/filters are presented and discussed.Between the different ways to minimize/eliminate harmonics active power filters are most prominent one.

Abstract:

The paper presents a methodology for determination of harmonic iron losses in laminated iron cores under both sinusoidal and sinusoidal pulse width modulated voltage excitations (SPWM) excitation for various frequencies. The method is based on measurements performed by using a convenient Epstein device supplied by a sinusoidal and a SPWM source, which are stored and processed in a PC by using an appropriate data acquisition card. It is shown that the switching frequency does not considerably affect iron losses under SPWM supply and vary non-linearly with flux density with respect to the ones m

Abstract:

This study simplifies iUPQC administration by employing a dual three-phase design, which makes the methodology behind the study more transparent. By utilising a parallel (shunt) and series active filter, it is possible to limit the amount of harmonics and unbalances produced by the iUPQC. When compared to a conventional UPQC, an iUPQC modifies the series filter in such a way that it operates as a sinusoidal current source. This is in contrast to a conventional UPQC. Since the iUPQC is regulated using voltage and current sinusoidal references rather than non-sinusoidal references, the frequency

Abstract:

The approaches to the control of the hybrid VAR compensator are considered. A hybrid VAR compensator is a passive and active compensator connected in series. The passive part is represented by a thyristor-switched capacitor bank. The power part of the active part is implemented on the basis of an autonomous voltage inverter, connected through a voltage transformer in series with a passive part. Most of the reactive power is compensated by means of the compensator’s passive part. The hybrid compensator combines the advantages of passive (low price, reliability) and active compensators (possibil

A mixed mode control strategy for Unified Power Quality Conditioner (UPQC), which involves no transformation, is presented and demonstrated for compensating the power quality problems under non sinusoidal supply condition in a three phase distribution system. UPQC is a combination of Series Active Power Filter (SAPF) and Parallel Active Power Filter (PAPF) with a common dc link. The series compensation voltage and shunt compensation current are controlled in the present work by SPWM switching of SAPF and hysteresis control of PAPF respectively.

This paper presents a new framework based on geometric algebra (GA) to solve and analyse three-phase balanced electrical circuits under sinusoidal and non-sinusoidal conditions. The proposed approach is an exploratory application of the geometric algebra power theory (GAPoT) to multiple-phase systems. A definition of geometric apparent power for three-phase systems, that complies with the energy conservation principle, is also introduced. Power calculations are performed in a multi-dimensional Euclidean space where cross effects between voltage and current harmonics are taken into consideratio
