Research of Multi-source Perception and Intelligent Diagnosis Technology of Outdoor Installation Protection Based on Data Syncretism

In this paper, summarizing the problems in the operation and maintenance, and based on data syncretism, research which is on the outdoor installation protection of multi-source perception and intelligent diagnosis technology, designs an outdoor installation protection perception and operational maintenance platform that highly integrated protection on-line monitoring and diagnosis, protection information sub-station, power system dynamic recording equipment and network message recording and analysis device as one system, and expounds in detail the system architecture of the platform, software framework, realization principle and key technology. The platform through the multi-source data acquisition, and the data sharing between each module and system integration, implements the outdoor installation protection multi-source perception and intelligent diagnosis, improving the efficiency and convenience of field operation and maintenance work, for outdoor installation protection of the safe and stable operation is of great significance. The platform has been successfully carried out in substation pilot application, achieving good results.
