The current research progress and problems of grid fault diagnosis are analyzed, and the idea of information fusion is introduced to the process of assistant decision-making for fault diagnosis. Through matching the data, feature and decision-making concept of information fusion with the concrete subjects in grid fault diagnosis, an assistant decision-making structure of grid fault diagnosis is constructed based on multilayer information fusion. The combination of fault diagnosis method for Petri-net and fault matching method for WAMS data is applied to the feature level fusion of assistant decision-making, and the proposed assistant decision-making method is practiced, which solves the problem of incomplete information in grid fault diagnosis, and provides a reference for the research on advanced application of smart grid in the future.
