6 FAQs about [Energy storage cable field analysis and design scheme]

What are the recommendations for future research on dynamic power cables?

Recommendations for future research: multi-physics simulations, analysis methods, and test standardisation. This review paper presents a comprehensive analysis of the mechanical design and analysis of dynamic power cables for marine renewable energy applications, focusing on research from the last two decades.

How complex are dynamic power cable structures in FEA modelling?

However, the complexity of dynamic power cable structures poses several challenges in FEA modelling. The cable’s cross-section consists of multiple components with different materials and complex contact conditions, leading to a high degree of non-linearity in the analysis.

What is dynamic power cable analysis?

Another critical aspect of dynamic power cable analysis is assessing the cable’s capacity or strength under combined loading scenarios, such as simultaneous bending and axial tension It is important to note that the strength of dynamic power cables is often characterised by their MBR due to the cables’ relatively low flexural stiffness.

What software is used to analyze cable stress distribution?

The results from the global analysis are then used as input for local analysis, which focuses on the stress distribution within the cable’s cross-section. Software tools like Helica (Skeie et al., 2012, DNV GL, 2024) or UFLEX (SINTEF, 2023) are commonly employed for this purpose.

Can a beam FE model accurately represent helically stranded cables?

The proposed beam FE model considers wire-to-wire contacts and elasto-plastic material behaviour, which are essential factors in capturing the complex mechanical behaviour of helically stranded cables. By incorporating these aspects, the model could accurately represent the cable’s response under various loading conditions.

How can optimisation improve the life of dynamic power cables?

The optimisation of these auxiliaries, in terms of materials, geometry, and manufacturing processes, could lead to more efficient and reliable cable protection systems, ultimately reducing the risk of cable failure and extending the service life of dynamic power cables.
