DC conduction in polyolefins – improved Power Capacitors and HV Cables for a sustainable use of electrical energy

This project will develop improved simulation models for conductivity in insulating polymeric materials, polyolefines, which are used in two vital components in high voltage direct current (HVDC) transmission systems: DC power cables between converter stations, and power capacitors which occupy a large part of the stations.

These two products are important for the transition to a fossil-free electrical grid. HVDC cables are needed for offshore wind farms, when further out to sea, more powerful cables are needed. Improved insulation materials help to ensure that higher voltage can be used, which results in lower losses.

It also provides higher energy density in the capacitors, which results in more compact converter stations, which is desirable at sea.

The new simulation models will be able to increase the development speed and manufacturing of novel polyolefins with reduced environmental impact, as well as increase the understanding of the use of these materials in HVDC insulation.
