To study the DC operation parameters of the 10 kV AC cable in different laying modes and DC operation topologies, according to the example of the three-core cross-linked polyethylene (XLPE) cable widely used in 10 kV AC distribution network, the temperature field, flow field and electric field coupling simulation models are established through finite element simulation software. The temperature field, the flow field, the steady electric field and the transient electric field are analyzed respectively, in the cases of the cable laid in the soil, pipeline and trench (three laying modes) and operating in the bipole, monopole and triple (three-wire bipole structure-high voltage direct current, TWBS-HVDC) DC operation modes (three DC operation topologies). The results show that for the same laying mode, the TWBS-HVDC has the highest DC ampacity, while the monopole mode has the lowest DC ampacity. The DC voltage levels of the 10 kV AC cable in the three laying modes and three DC operation topologies are 10 kV and leave a certain voltage margin. The cable in the trench and monopole mode has the highest maximum DC transmission power, i.e., 13.2 MW, whereas the cable in the pipeline and bipole mode has the lowest maximum DC transmission power i.e., 8.7 MW. The maximum transmission power of the AC cable will have a significant increase after the cable is converted into DC operation.
