Abstract

The invention discloses a method for analyzing functional damage degrees of secondary equipment and a secondary system of an intelligent substation. The method comprises: step one, establishing a functional base and determining a concrete object for a damage degree analysis; step two, establishing a function condition base and determining an influence factor; step three, establishing a logic matrix and forming function and condition logic expressions by the functional logic matrix; step four, carrying out function condition base shooting to obtain a functional condition state; step five, on the basis of the functional condition state and the function and condition logic expressions, analyzing a function operation state; and step six, analyzing functional damage degrees of secondary equipment and a secondary system based on the functional operation state analysis, thereby realizing functional damage degree analysis, graphic expression and fault positioning of the secondary equipment and secondary system. Therefore, the intelligent diagnosis capability of the secondary system defect is improved and a technical support is provided for operation and maintenance.

Description

technical field [0001] The invention relates to the field of intelligent substation research, in particular to a method for analyzing the damage degree of secondary equipment and secondary system functions of the intelligent substation. Background technique [0002] Compared with traditional substations, there are abundant online monitoring information of secondary equipment and secondary systems in the smart substation process layer and station control layer network. Due to the strong functional correlation between information, refining and comprehensive analysis of information is helpful to comprehensively and intuitively understand the operation status of secondary equipment and secondary systems, provide technical support for the operation and maintenance of smart substations, and improve the efficiency of smart substations. intelligence level. [0003] The operating status of secondary equipment and secondary system functions is related to the safe and stable operation...
