Harmonic compensation using advanced electric machines

IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.37243), 2002
In this paper, a new electromechanical active harmonic filter is proposed. The proposed electromechanical harmonic filter is essentially a rotating asymmetric air gap concentrated winding synchronous machine (AACWSM) with AC and DC excitation field.

A decoupled series compensator for voltage regulation and harmonic compensation

PESC Record. 27th Annual IEEE Power Electronics Specialists Conference, 2002
This paper presents a new power converter topology for the series VAr compensation of AC power systems. The scheme employs a multi-step inverter for compensation at fundamental frequency and a PWM inverter for harmonic compensation. The inverters are decoupled in such a manner that the high-frequency harmonic compensation module uses an inverter of low

HARMONIC CURRENTS COMPENSATION SCHEME FOR ELECTRICAL DISTRIBUTION SYSTEMS

IFAC Proceedings Volumes, 1983
Abstract The authors present a novel method of compensating line current harmonics by the use of another power electronic converter, which operates at a much higher frequency in conjunction with the supply mains system. The high frequency converter generates only the harmonic currents as required by the converter type loads connected to the system ...

Torque Harmonic Compensation in a Synchronous Reluctance Motor

IEEE Transactions on Energy Conversion, 2006
The torque behavior of a synchronous reluctance motor [including the permanent magnet (PM) assisted configuration] is deeply analyzed. An analytical model is developed, showing the dependence of the torque ripple on the rotor geometry. The results of this model allow to individuate the position of the flux--barrier ends so as to minimize the torque ...

The problem of harmonic compensators location

European Transactions on Electrical Power, 1996
AbstractCurrent harmonics can be eliminated in each individual load. Such a compensation generally must be expensive. Harmonics are partly compensated between individual consumers. Therefore, the compensation of group of consumers seems to need lower cost than individual compensation. In the case of group compensation there are two possible approaches.

Harmonic and interharmonic currents compensation in DC line

2014 International Symposium on Power Electronics, Electrical Drives, Automation and Motion, 2014
In this paper a strategy for the compensation of harmonic currents in DC bus has been proposed. By means of a multilevel converter, low amplitude harmonic currents due to the interaction between primary converters operating in different conditions and connected to the same DC bus, are compensated.

Discrete controlled harmonic and reactive power compensator

Conference Record of the 1988 IEEE Industry Applications Society Annual Meeting, 2003
Unwanted harmonic content and nonunity power factor of the current resulting from three-phase power electronic loads are compensated with a simple GTO (gate turn-off) thyristor bridge. The bridge, the simulation method, and the design of the discrete controller for the bridge are described.

Harmonic compensation using residential PV interfacing inverter

IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012
The increased number of nonlinear residential loads in today's typical home and power electronics based distributed generation (DG) systems is a growing concern for the utility companies due to the power quality issues. However, properly controlled DG-grid interfacing converters are able to improve the distribution system power quality.
