Advances in power electronics, increasing share of renewables in the energy system and e-mobility cause an increase of disturbances in the frequency range 2-150 kHz, also known as supraharmonics. A rigorous, credible and agreed measurement framework is essential to evaluate electromagnetic compatibility (EMC) in this frequency range. While a normative method exists for measuring equipment emission in the laboratory, no normative method exists yet for the measurement of supraharmonic disturbance levels in the grid. After a brief introduction into the topic and the present status quo of standardization, this lecture will illustrate the need for a normative grid measurement method and compares several proposals presently under discussion in IEC SC77A WG9 for the next edition of IEC 61000-4-30. The pros and cons of the methods are explained and complemented by several practical measurement examples.

About the speaker:
Dr Jan Meyer received the Dipl.-Ing. and Ph.D. degrees in electrical power engineering as well as the postdoctoral qualification in Power Quality from Technische Universitaet Dresden, Dresden, Germany, in 1994, 2004 and 2018 respectively. He is currently with Technische Universität Dresden as Senior Lecturer and Leader of the Power Quality Research Team.
His research interests include network disturbances and their assessment, especially for distortion below and above 2 kHz, accuracy of Power Quality measurements as well as analysis of big data amounts from Power Quality measurement campaigns. He is member of several national and international working groups on EMC standardization, several CIGRE working groups and the CIRED technical committee. He gives regular speeches on recent topics in the field of Power Quality and is organizer of seminars in the field of network disturbances and its assessment.
