Abstract:
The invention relates to electrical network topological error identification method based on mixed evaluation, belonging to the network topological error identification technique of evaluating the condition of electrical system. Said method comprises: detection: checking the correspondence between each branch switch telemetry and branch current measurement, attaining relative suspected switch integration when they are not corresponding; evaluation and identification: using the topological structure corresponded to the suspected switch integration to form a possible correct topological structure integration, utilizing mixed evaluation method to find a network topological structure which can make the remote measurement and telemetry total information be damaged least, as a correct topological from said possible topological structure integration; correcting the switch telemetry: correcting the fault telemetry according to said correct topological structure. The invention can integrated take regard of network topological information of remote measurement and telemetry, to improve the accuracy of topological error identification.
