In order to accurately evaluate the health status of relay protection equipment and improve the management level of relay protection equipment, a relay protection status evaluation method based on multi-source information fusion technology was proposed, in which the technical characteristics of relay protection was fully considered. The evaluation system and index of relay protection were established. The key technical problems of the multi-source information fusion technology used in the state evaluation of relay protection, the function and structure model of state evaluation of relay protection and its application in the life cycle equipment management were solved. The state evaluation method of relay protection was established. Combining with the current situation of life cycle management of relay protection equipment, a solution to the application of relay protection status evaluation results in the process of equipment life cycle management was put forward. A relay protection status maintenance system based on multi-source information fusion technology was developed, being applied to many dispatching units. The correctness and practicability of this method was verifiesd.
