The invention discloses a network monitoring method for intelligent components, which belongs to the technical field of electric power automation and is used for monitoring and evaluation analysis of running states of the intelligent components of an intelligent substation. The intelligent components are mounted in an intelligent component cabinet and transferred to high-voltage equipment for separation; except some intelligent components for necessary external communication in the cabinet, most intelligent components operate in a black box, and no any monitoring means for the intelligent components is provided. According to the network monitoring method for intelligent components, comprehensive monitoring and recording of operation in the cabinet is realized through network monitoring, SNMP (simple network management protocol) information management and environmental monitoring, online analysis and early warning are realized by using status evaluation analysis, and a long-distance retrival means is provided through a Web access module. With adoption of the network monitoring method for intelligent components, monitoring and intelligentization of the intelligent substation are more comprehensive, the safe operating level is improved, and an ideal means for monitoring of real-time operating status of the intelligent components and fault diagnosis of the intelligent components is provided.
