Abstract

The invention discloses a high-performance electrical network real-time topology analysis method. The objective of the invention is to solve technical problems of high complex degree, poor scalability and low real-time performance of an electrical network topology analysis method in the prior art. According to the method of the invention, electrical network topology analysis is established based on specific switch actions; the switch actions of an electrical system are monitored; and calculation results of an adjacency matrix and a full-connectivity matrix before the action of the switch are fully utilized, so that a new adjacency matrix and a new full-connectivity matrix can be obtained; and calculated data can be utilized efficiently, and a large quantity of repeat calculation processes can be decreased. The high-performance electrical network real-time topology analysis method of the invention can be widely applied to topology analysis and topology coloring of various kinds of automatic monitoring fields involving complex circuits.

Description
