Successful EMPIR workshop on measurement methods for electrical interference

Workshop presentations are now available

Successful online workshop

The consortium of EMPIR project Grid measurements of 2 kHz - 150 kHz harmonics to support normative emission limits for mass-market electrical goods (18NRM05, supraEMI) recently hosted an online workshop, attended by 70 people from industry and the standardisation community, including representatives from the International Electrotechnical Commission (IEC).

The two-hour workshop, entitled ‘Measurement methods for the frequency range 2-150 kHz (Supraharmonics)’ provided a forum to discuss issues relating to how renewables and electric vehicle chargers (EVs) can cause malfunction and the shortening of service life of typical electronic consumer products such as TVs, PCs and kitchen appliances, as well as causing glitches in control systems and critical infrastructure. New measurement methods are urgently needed to enable regulation through standardisation and the involvement of several conveners of key IEC committees at this workshop was particularly significant.

The presentations from the workshop are available:

The project
 

The EMPIR project supraEMI is working towards formulating and validating a new normative method to measure supraharmonic emissions in electricity grids, conduct a laboratory comparison of the method, and contribute to standards development. The resulting measurement framework will provide evidence for product emission limits and support future regulation. New normative methods and apparatus will give rise to new services, while standards for mass-market goods will help ensure reliable operation of products, protect the grid, help develop smart grids, and prevent renewable energy operational issues.

Project coordinator Paul Wright from NPL said

‘There is increasing concern about the build-up of supraharmonics as we continue to add more renewables and EVs to our grids. These green deal technologies are essential to our future, yet we must ensure that they all work together without widespread interference and malfunction.  The importance of this issue was bourne out by the seniority of the representatives at this workshop and we were delighted to present our project progress so far towards developing measurement algorithms to support the future regulation of supraharmonics.’


This EMPIR project is co-funded by the European Union's Horizon 2020 research and innovation programme and the EMPIR Participating States.
