Intelligent test technology of relay protection based on intelligent recorder

Based on the preventive measures of incorrect operation of relay protection, the shortage of periodic power cut test technology is analyzed, and the intelligent test technology of relay protection based on intelligent recorder is put forward. This paper studies a kind of real-time Operation Information based on the intelligent recorder on-line monitoring and protection device, and predicts the condition of remote non-power-off inspection,the advantages of remote non-power-off inspection in reducing operation risk, improving working efficiency and reducing the difficulty of primary equipment power-off are further expounded. Finally, the feasibility and completeness of the remote non-blackout test technology of relay protection based on intelligent recorder are verified by engineering application, which provides reference for engineering design and intelligent operation and maintenance.
