Evaluation Tags Calculation of Relay Protection Equipment Based on Improved Metric Learning Algorithm

Extracting characteristic attribute sets covering device ontology, operating state, maintenance and other equipment life trajectory process, establishing the tagging model of relay protection equipment and comprehensively displaying the protection equipment information, which can provide technical support for the operation, maintenance and technical upgrading of relay protection equipment efficiently. This paper analyzes the basic attributes and behavior attributes of the relay protection equipment, and establishes the tagging device model of the relay protection equipment including static class, dynamic class and evaluation class. The basic attributes and behavior attributes of relay protection equipment are analyzed, and the improved measurement learning algorithm is used, that is, the index function of applicability is introduced, the appropriate mapping matrix is searched, and the evaluation tags of protection equipment are established. The effectiveness of the algorithm is verified by a numerical example.
