The invention provides an induced voltage obtaining method and device, electronic equipment and a storage medium, and relates to the technical field of complex cables, and the method comprises the steps: simplifying a to-be-tested cable line into an equivalent circuit; segmenting the equivalent circuit at segment nodes to generate a segment model; obtaining electrical parameters of the segmented model, and obtaining an output current based on the electrical parameters; setting series impedance, parallel impedance, interconnection impedance and shunt impedance in sequence to obtain updated electrical parameters of the electrical parameters; connecting a virtual cable with the segmentation model to determine different grounding modes according to the virtual cable and the updated electrical parameters; and obtaining an induced voltage according to the updated electrical parameter and the updated output current corresponding to the grounding mode. In a complex cable system, the induced voltage can be accurately
