Research and Application Scenario of Risk Early Warning System for Large Power Grid Considering Intensive Transmission Channel Disaster

By analyzing the application status of intensive transmission channel monitoring, this paper put forward the bottleneck and key issues of integrated supervision in this field. Through the requirement analysis of risk early warning of large power grid, this paper has proposed the technical difficulties of the external disasters of intensive transmission channels and data sources , analyzed the data status and data characteristics of the main external environment affecting intensive transmission channels, such as meteorology, typhoon, wildfire, icing, lightning, etc., and designed and implemented the multi-source data sharing forms and specific technical route based on the whole network. According to the characteristics of risk early warning data sources of large power grid considering intensive transmission channel disasters, this paper has designed the technical architecture of data specification, put forward key technologies including standardization of data modeling, structuring of data storage, global data sharing, and service-oriented data usage.This paper has proposed approaches of relational model building and risk assessment between external disasters and key equipment in intensive transmission channels, and finally looked into the future of the application of network-wide multi-source data fusion technology in ensuring the safe and stable operation of large power grids.
