Накратко на български

Подморските кабели за пренос на ток с високо напрежение се анализират чрез нови математически модели за по-точно изчисляване на параметрите им. Това помага за по-ефективното свързване на офшорни вятърни паркове към електрическите мрежи на европейските държави.

Cables for HVDC Offshore Transmission Networks

Driven by current perspectives on the potential of renewable resources, technological advances in the areas of offshore wind as well as solar and storage systems are setting the pace towards the fulfilment of sustainable strategies. In order to face such a challenge, EU countries are focusing their efforts on cost-effective solutions to enable a more effective integration of renewable energy. Energy hubs for offshore wind production and interconnections between nations form a crucial part of the European vision for a greener electricity market. Aware of the fact that high voltage cables are quite complex and with a different electric behaviour to traditional overhead lines, there is still a gap regarding the proper modelling of submarine HVDC cables since field measurements show the lack of confidence in simulation results with regard to the voltage and current profiles on the core, sheath and armour layers. To face the ambitious plan to develop an offshore network connecting the Nations bordering the North Sea to harness offshore wind energy efficiently, the CABOTioN project focused on the development of an innovative approach for identification of per-unit-length (p.u.l) parameters of submarine HVDC cables suitable for incorporation in third-party software in a straightforward way. The action exploited the Method of Moments with the Surface Admittance Operator (MoM-SO) and a modified version of Pollaczek's formulae to account for the effects of the cable cross-section and the external media. The proposed approach was validated against the Finite Element Method (FEM), and the impact of more accurate cable parameters on typical analysis involving submarine HVDC cables has been assessed on system-level studies for the connection of offshore wind farms to the transmission grid using HVDC technology or for an HVDC interconnection between AC grids. The obtained outcomes have made it possible to measure the variances that occur when simplifying assumptions are implemented. This allows for a clearer understanding of the impact these assumptions have on the accuracy of the results. By quantifying these deviations, we can better assess the accuracy of simplified models in representing complex systems. The project will contribute to the development of cost-effective green projects for the integration of renewable energy and the creation of a unified electricity market.

Цел на проекта

A sustainable energy network must comply with the usage of offshore wind farms and the sharing of surplus renewable energy without a dangerous carbon footprint. Amongst the possible technologies to foster the energy transition one way is to rely on HVDC transmission resorting to submarine cables for energy transfer. However, field measurements show the lack of confidence in simulation results with regard to the voltage and current profiles on the core, sheath or armour. A proper representation of the magnetic behaviour of the armour and the impact of the sea and seabed for an overall assessment of the transient behaviour remain a challenge.The overall objective of CABOTioN is the development of an innovative approach for identification of per-unit-length parameters of submarine DC cables and a straightforward interface with simulation tools. The applicant will resort to up-to-date formulations to design a special-purpose tool to compute electrical parameters considerably faster than the Finite Element Method without a significant loss of accuracy. Therefore, evaluations will be conducted to assess the enhancements achieved with a more accurate model and compared with the common practice and measurements.Implemented at Aalborg University, and supervised by Prof Filipe da Silva and Prof Claus Bak, CABOTioN will bring outstanding competencies and utmost recognition internationally in the field of cable modelling. The secondment with Prof Correia de Barros will strengthen the competency as an independent researcher on a challenging theme.A two-way transfer of knowledge is guaranteed since the applicant has a solid background on development of system models and network solvers and the supervisors have vast experience on challenging research projects. Therefore, CABOTioN will contribute to enhance the European scientific excellence on the development of cost-effective green projects to find new, better and more economical ways of building offshore transmission grids.
