Abstract

The invention discloses a high-performance electrical network real-time topology analysis method in the field of electrical network technology, aiming to solve the technical problems of high complexity, poor scalability, and low real-time performance of the grid topology analysis method in the prior art . The topology analysis of the electrical network in the present invention is based on the specific switching action. By monitoring the switching action of the electrical system, the operation results of the adjacency matrix and the full connectivity matrix before the switching action are fully utilized to obtain a brand new adjacency matrix and full connectivity. The matrix enables the effective use of the calculated data and reduces a large number of repeated calculation processes. The invention can be widely applied to topology analysis and topology coloring in various fields of automatic monitoring involving complex circuits.
