Condition Assessment of Power Transformers Through the Integration of Historical and On-line Data in a Multi-Agent System

[摘要] Power transformers undergo numerous different tests during their life cycle. Some are applied just when they are new, some (non- invasive tests) are repeated in a regular basis, and others only when a defect is suspected. Maintenance engineers specialize in a few tests, sometimes only one, so an expert who can interpret and combine the results of several tests to reach a more valuable conclusion is rare. In addition to maintenance tests, frequently power transformers are monitored by on-line devices which generate more data to be analyzed. This paper describes the development and the implementation of a multi-agent system for integrated diagnosis of power transformers. The system is composed of multiple agents. The social ability and cooperation between the agents lead to the final diagnosis and to other relevant conclusions through various monitoring technologies, diagnostic methods, and data sources...
