Online detection index system analysis method for relay protection equipment related to time

Abstract

The invention discloses an online detection index system analysis method for relay protection equipment related to time. The method comprises the following six steps: step 101, determining the type of a piece of relay protection equipment and a statute type; step 102, according to the type of the relay protection equipment and the statute type, reading related indexes, statute feature codes corresponding to the indexes, and a compute mode from a predefined index and statute feature library of relay protection equipment; step 103, capturing communication messages; step 104, matching with the statute feature codes corresponding to the online detection indexes; step 105, according to the index compute mode, determining whether a computational condition is satisfied; step 106, and calculating an index value. Through establishing a communication monitoring mechanism independent to an automation system, and extracting functional performance characteristic parameters reflecting health of the relay protection equipment on line, the method realizes online monitoring of the relay protection equipment.
