Considering the problems that have appeared lately related to the quality of power / energy and to the electromagnetic interferences at low frequency, some debates must take place.
There is still no clear delimitation between the higher frequency up to which power / energy quality issues must be judged and from which lower frequency the phenomena of electromagnetic interference must be discussed.
Consequently, the measures to reduce the unwanted effects, with influences on other electrical and electronic equipment, are not very clearly delimited. The filters used in the area of power / energy quality do not coincide with those used to reduce low frequency emissions. Active, hybrid or passive filters reduce harmonics especially of low order and have a limited frequency range - according to quality standards, while low frequency EMC filters are designed / made for a wider frequency range, being often broadband filters. The harmonic currents in the two situations have important values (for filters made to improve the quality of electricity), while to reduce electromagnetic interference at low frequency the currents generally have lower values.
Data measurement and processing involves high-performance data acquisition systems with different processing methods. The analysis in the field of power/energy quality is mainly based on Fourier series decomposition (with frequency domain analysis), while analyzes related to the reduction of electromagnetic interference require combined analysis (time-frequency).
Analyzes, especially in three-phase systems, need to be followed by progress in data acquisition and processing in the 70-150 kHz range.
Contributions are required in the 2 (3) kHz-150 kHz frequency range, with an extension up to 1 GHz, including the development of new standards for these frequency ranges.
The workshop aims to contribute to the debates on the issues previously reported and to help develop new standards, adapted to current requirements in the field of PQ and EMC.
