Abstract

The UK electrical power network is currently transitioning towards a 'smart grid'. This will be driven by the take up of green devices such as electric vehicle charging units, solar generation and district heating schemes. In order for Distribution Network Operators (DNO) in the UK to balance supply and demand they will need to maximise utilisation of existing assets under challenging conditions. This paper details a Finite Element Magnetic Method (FEMM) model used to simulate the thermal impact on cable insulation asset lifespan for two unique aspects; the non-standard burial of adjacent Low Voltage (LV) electrical power cables on high voltage (HV) electrical power cables; and a typical district heating scheme. Principle results have shown a conductor temperature rise of 14 oC in HV cables under non-standard LV cable burial conditions, which could result in significant deterioration in cable lifespan. The introduction of a district heating scheme indicates a HV conductor temperature rise of 4.5 oC, which is close to the manufacturer's insulation deterioration tolerance.
