A method for information fusion of electric power equipment

Abstract

The invention relates to an information fusion method for electric equipment, the method comprising: collecting state information of primary equipment; expanding the online monitoring logic node of secondary equipment in the IEC61850 information model, and collecting the online monitoring state information of the secondary equipment ; Obtain the equipment information of the production management system through Web service; integrate the status information of the primary equipment corresponding to the equipment, the online monitoring status information of the secondary equipment, and the equipment information of the production management system. The method provided by the invention can integrate primary and secondary equipment status monitoring data, and perform information interaction with the production management system, realize the unification of relevant equipment information, and provide support for integration of unattended duty and regulation.

Description

technical field [0001] The invention relates to the field of equipment state monitoring, in particular to an information fusion method for electric equipment. Background technique [0002] The intelligent substation adopts the IEC 61850 standard, intelligent electronic equipment and information communication technology to establish a standardized, digital and networked substation. The panoramic monitoring of power equipment (including primary and secondary equipment) is an important goal of the intelligent substation. Panoramic monitoring relies on equipment status monitoring technology, and equipment status monitoring has two methods: offline detection and online monitoring. Off-line detection has the characteristics of non-real-time, and requires power-off test, which may not reflect the actual situation of the equipment. Therefore, online monitoring has become an important means to improve equipment reliability and system availability. [0003] Compared with the status m...

Problems solved by technology

As the medium of information, secondary equipment is the focus of attention of operation and maintenance personnel. At present, secondary equipment only has a self-test function, which cannot meet the needs of remote monitoring. Intelligent electronic equipment status monitoring system for important parameters and links such as , secondary loop, etc.

The production management system focuses on management and is mainly used in departments closely related to production management. It cannot directly provide substations with necessary information such as equipment maintenance test management, fault management, inspection management, defect management, operating status, and nameplates. Substation operation and maintenance Personnel need to access the master station of the production management system through the Web to obtain local information, which brings inconvenience to on-site operation and maintenance
