Beschreibung
Zusammenfassung:	The invention discloses a data and physical dual-drive short-circuit current parameter identification method and system, and relates to the technical field of short-circuit current parameter identification, and the method comprises the steps: determining key parameters of a wind generating set; according to the voltage and flux linkage equation under the three-phase static coordinate system when the crowbar protection DFIG machine end is in three-phase short circuit, a state equation with flux linkage as a state variable is obtained; solving a root and a correction factor of the state equation, proposing crowbar protection, and obtaining a stator and rotor coupled short-circuit current analytic expression; a short-circuit current calculation model is incorporated into network learning to carry out physical constraint on a network, and a pure data driving result is guided and corrected. In the training stage, the requirements of the deep learning network on the quality and the number of samples are reduced, th
