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 ...

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 ...

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.

Harmonic voltage measurements in the low voltage distribution grid
2015 16th International Scientific Conference on Electric Power Engineering (EPE), 2015The supply territory of the company E.ON Distribution in the Czech Republic (run by the company E.ON Czech Republic) accounts for approximately 1.5 million customers. A problem was detected with harmonic voltage in approximately 14% low voltage (LV) distribution grids [6] without the differentiation of harmonic order.
