Evaluating method and device for power system transient stability

The embodiment of the invention provides evaluating method and device for power system transient stability, wherein the method comprise the steps of: Acquiring operation condition data of a power system to be tested; Inputting operation condition data of the power system to be tested to a target transient stability evaluating model, and outputting an evaluation result; Wherein the target transientstability evaluating model is selected from a set of the transient stability evaluating models according to the operation condition data, the set of transient stability evaluating model includes at least two transient stability evaluating models, the set of transient stability evaluating models is obtained after the normalization of a plurality of pre-trained transient stability evaluating models, and each of the plurality of pre-trained transient stability evaluating models correspond to a working condition type. According to the evaluating method and device for power system transient stability, the problem of diffe
