Abstract

The invention discloses an electric power secondary equipment alarm method and system. The method comprises the following steps: employing transformer substation primary equipment monitoring alarm, secondary equipment monitoring alarm, auxiliary equipment monitoring alarm, system operation alarm and network security alarm data, and carrying out the flexible self-defined configuration of an expert reasoning rule base; and analyzing the logic relationship of occurrence time, space, topology and the like among the discrete signals, and finally identifying a corresponding comprehensive alarm event result through event intelligent reasoning analysis. According to the invention, some defects and problems existing in a traditional solidified expert rule alarm system, such as slow system updating, disjunction between equipment manufacturers and field information and incapability of finding novel alarms in time, are solved, so that the sensing level of substation equipment operation monitoring is greatly improved, and finally the accident handling efficiency of intelligent substation regulation and control personnel is improved.

Description

technical field [0001] The invention belongs to the technical field of electric power system scheduling automation and intelligent substation monitoring, and in particular relates to an alarm method and system for electric secondary equipment. Background technique [0002] The fault alarm of power secondary equipment is developing in the direction of automation and intelligence. Scholars, experts, enterprises and institutions at home and abroad have conducted many studies on this issue. Some power system fault diagnosis expert systems based on positive and negative reasoning are used for fault diagnosis and alarm of power grid primary equipment; some fault judgment expert systems are based on switch trip information; Research on alarm; some use neural network and expert system mixed together; some combine rough set theory, neural network and expert system to realize fault diagnosis expert system for substation primary equipment, which uses rough set theory and clustering tec...
