Human body electric shock identification method and device based on Prony algorithm

The invention relates to the technical field of power grids, and provides a human body electric shock method and device based on a Prony algorithm, computer equipment and a storage medium. The method comprises the following steps: sampling a to-be-identified circuit to obtain residual current sampling data, fitting the residual current sampling data through a Prony algorithm, obtaining an attenuated direct current component according to a fitting result, further extracting a target attenuated direct current component from the attenuated direct current component according to frequency and amplitude, and identifying the target attenuated direct current component. And comparing the target attenuation direct-current component with a preset attenuation direct-current component threshold value, and determining a human body electric shock identification result of the circuit to be identified according to a comparison result. According to the method, on the basis that the human body electric shock has the attenuated
