Induced losses in non-magnetically armoured HVAC windfarm export cables
Abstract
Presently, IEC 60287-1-1 is used to calculate the ratio of induced loss in a cable’s metal sheath to its conductor loss (λ1), considering uniform current density in both conductors and sheaths. Although this assumption is reasonable for smaller cables, it becomes questionable for larger cables in close proximity, such as three-core (3C) export cables in Offshore Wind Farm (OWF) projects. The present study employs 2-D Finite Element (FE) models to evaluate how accurate the Standard method for calculating the λ1 factor is in cables with non-magnetic armour. Their validity is further enhanced by measurements in a 3x1000 mm2 155 kV unarmoured cable. IEC 60287 appears to overestimate the temperature, particularly for larger conductor sizes, by up to 7°C. Finally, suitable Reductive Factors (RFs) are derived which could improve the accuracy of the IEC method.
