The invention discloses a
relay protection setting value analysis and
verification method and
system, and relates to the technical field of
relay protection, and the method comprises the steps: calculating the final
coupling strength through employing an exponential
coupling formula method, and constructing a
coupling matrix through employing a
coupling matrix standardization method; performing eigendecomposition on the updated manifold center by using a eigendecomposition
verification method, organizing into a third-order
tensor, calculating
Gaussian kernel similarity between the fault feature and the historical fault feature by using a
Gaussian kernel similarity calculation method, and generating a similarity
score; and calculating constant value deviation and updating. By introducing differential geometry, information geometry and
quantum state coupling theories, a
modal covariance tensor model based on a symmetric positive definite manifold is constructed, an index coupling mechanism combining an inter-
modal Riemannian distance, a tension index and disturbance coding is put forward, the
structural integrity and
coupling strength characterization capability of
modal information fusion are improved, and the accuracy of modal
information fusion is improved. And the scientificity and
operability of constant value evaluation are enhanced.
