The invention discloses an electrical equipment matching method and system. The method comprises the steps that according to the name sample of electrical equipment, a matched knowledge base is established; reference equipment names and names of equipment to be matched are obtained, equipment objects of the reference equipment names are obtained, and according to the equipment objects of the reference equipment names, corresponding feature vector expressions and matching rules are obtained from the matched knowledge base; according to the feature vector expressions, the feature vectors of the reference equipment names and the feature vectors of the names of the equipment to be matched are extracted from the reference equipment names and the names of the equipment to be matched; and according to the matching rule, whether the feature vectors of the reference equipment names and the feature vectors of the names of the equipment to be matched are equivalent is judged, and if yes, the matching relationship of the reference equipment names and the names of the equipment to be matched is established. The electrical equipment with different names and marks can be identified easily, and parameter information infusion and sharing of different electrical production business systems are achieved.
