Cable induced voltage determination method and device based on sheath layering model

The invention relates to the technical field of computers, in particular to a cable induced voltage determination method and device based on a sheath layering model. The method comprises the following steps: determining a geometric structure and electrical connection information corresponding to a cable line to be detected by adopting virtual node, unequal normalization and same-direction normalization technologies; according to the geometric structure and the electrical connection information, establishing a cable sheath induced voltage calculation layering model; and carrying out matrix order reduction calculation on the cable sheath induced voltage calculation hierarchical model to obtain the cable induced voltage corresponding to the cable line to be measured. The method can be used for cable lines such as multi-loop parallel cables with different grounding modes and multi-loop cables with different directions, unequal lengths and unparallel, and the calculation process of the cable induced voltage can be
