Harmonic Droop Controller to Reduce the Voltage Harmonics of Inverters
IEEE Transactions on Industrial Electronics, 2013In this paper, the load and/or grid connected to an inverter is modeled as the combination of voltage sources and current sources at harmonic frequencies. As a result, the system can be analyzed at each individual frequency, which avoids the difficulty in defining the reactive power for a system with different frequencies because it is now defined at ...

Considerations on probabilistic harmonic voltages
2003 IEEE Power Engineering Society General Meeting (IEEE Cat. No.03CH37491), 2004Some considerations on probabilistic harmonic voltages are given. Reference is made to modeling both for provisional analyses and to measurements for compliance with limits fixed by standards. Numerical and experimental case-studies are developed and analyzed.

Harmonic study in electromagnetic voltage transformers
2012 IEEE International Symposium on Industrial Electronics, 2012Ferroresonance is a complex electrical phenomenon which may cause overvoltages and overcurrents in electrical power system disturbing the system reliability and continuous safe operating. The ability to predict or confirm ferroresonance depends primarily on the accuracy of the voltage transformer model used in the computer simulation. In this study, at

A shunt active harmonic filter based on a voltage detection method for harmonic voltage control
2004 IEEE International Conference on Electric Utility Deregulation, Restructuring and Power Technologies. Proceedings, 2004With the proliferation of electronic equipment in modern buildings, harmonics in low voltage distribution systems have received a great deal of attention. This paper discusses harmonic voltage control using a shunt active harmonic filter based on a voltage detection method. The control method is discussed first.

Current and Voltage Harmonics in the Powertrain of Electric Vehicles
IEEE Transactions on Vehicular Technology, 2020Switching electronics, such as the drive inverter, generate significant voltage and current harmonics with frequencies as low as a few kilohertz which are propagated throughout the complete electric powertrain and all connected components. With amplitudes up to several volts and dozens of amperes, such harmonics can cause significant problems and lead ...

Superposition of current and voltage harmonics
2018 ELEKTRO, 2018This paper deals with power quality that is aimed on voltage and current harmonics. The analysis describes the household appliances producing the harmonic interference, because they consist of semiconductor components. The next reason is that a large number of household appliances are operated in the same time.

Voltage harmonics compensator for high-voltage power supplies
2013 International Conference-Workshop Compatibility And Power Electronics, 2013In this paper, a practical solution for suppression of voltage harmonics in high-voltage power supplies is proposed. The solution is based on three single-phase series active-power filters (SAPF) inserted in a common point of a synchronous generator (SG) through an injection transformer.

Voltage and current harmonics caused by corona
Journal of the American Institute of Electrical Engineers, 1921THE FOLLOWING investigation was made to study the effects of corona in producing voltage and current harmonics in transmission systems. In the early work on corona in 1910 a very complete oscillographic study was made of voltage and current. It was found that the current wave of corona loss very much resembled the excitation current wave of a ...
