Online Monitoring Technology for Secondary Equipment of Substation Integrated Automation System
The importance of equipment health management is expounded based on online monitoring requirement of integrated automation system for power substation.Several factors affecting the health condition of secondary equipment for traditional power substation are analyzed,such as running environment,equipment performance and substation control network.There are three accesses to obtain online monitoring indexes:install sensors for the equipment operating conditions,read the equipment self-inspection information for the equipment performances; monitor and analyze communication messages for the intelligent equipment network statuses.The key technical issues including health index selection,data collection technology and evaluation and alarm method have been explored.The research results have been practiced and verified in the substation of Deqing County Power Supply Company.
