Broadband oscillation phenomenon detection method and device, storage medium and computer equipment

The invention discloses a broadband oscillation phenomenon detection method and device, a storage medium and computer equipment, which are applied to a power system comprising a generator. The method comprises the steps of collecting electric power parameters of an electric power system, and determining a z-domain impedance model of a generator in a global coordinate system according to the electric power parameters; acquiring an impedance model network of a receiving-end power grid in the power system, and aggregating the impedance model network to obtain a z-domain aggregated impedance model; calculating an impedance ratio according to the z-domain impedance model and the z-domain aggregation impedance model, and calculating Gerer disc track bands, distributed on a complex plane, of Gerer discs corresponding to two characteristic values of the impedance ratio under multiple frequencies; and determining a target point on the complex plane, and determining whether the broadband oscillation phenomenon occurs i
