Method for identifying abnormal operation data of transformer substation

The invention relates to a method for identifying abnormal operation data of a transformer substation, and belongs to the technical field of power data detection. The method comprises the following steps: dividing abnormal operation data into discontinuous abnormal operation data, interfered abnormal operation data and continuous abnormal operation data; according to the method, different identification methods are adopted to identify different types of operation abnormal data, kurtosis and skewness judgment is added to discontinuous operation abnormal data on the basis of an existing 3 method, and the problem of misjudgment of the existing 3 method is solved; as for disturbed operation abnormal data and continuous operation abnormal data, the spatial correlation degree between a single sensor and other sensors is adopted as an identification index to carry out operation abnormal data identification, and the problem of missed judgment of an existing three-method is solved; therefore, the abnormal operation da
