Abstract
The overall objective of NEWGEN is to develop and demonstrate new insulation materials, cable manufacturing solutions, online condition monitoring technologies, and comprehensive life and reliability modelling tools for the next-generation of extruded HVDC cables and cable systems, thereby fostering the reliability and resilience of the inter-connected European HVAC/-DC transmission grids. NEWGEN delivers new space charge mitigating additives for extruded HVDC insulation materials, as well as new industrial cable extrusion solutions for defect-free and cost-effective manufacturing of next generation thermoplastic HVDC cables. Moreover, NEWGEN will provide online global condition monitoring and novel pre-fault detection methods and instruments for assessing the health status of extruded HVDC cable systems, as well as comprehensive tools and models for the evaluation of life and reliability of extruded HVDC cable systems (cable, joints and terminations) under realistic operation conditions within HVAC/-AC grids (model demonstration via grid-simulations). The new sustainable insulation materials and extrusion solutions will contribute to improved dielectric performance and reliability of extruded insulations needed for reaching TRL maturity for higher rated voltages up to ±600 kV. The uniqueness of the NEWGEN concept is that it is not limited to any specific insulation compound or HV cable manufacturer, but rather the results will impact the whole European HV cable industry for reaching the next generation of reliable-by-design extruded HVDC cables. Moreover, the NEWGEN innovations for online condition monitoring and reliability modelling of HVDC cable systems will allow European transmission system operators (TSOs) to perform comprehensive monitoring and proactive maintenance for their HVDC cable system assets, and to ensure satisfactory firewall properties against disturbances in the hybrid AC/DC network.
