英文摘要： The traditional condition assessment of power equipment is mainly based on the mechanism and causality model built through theoretical analysis, simulation and experimental testing. In this project, large amount of information, including equipment condition information, grid operation information and meteorological information, which are collected through the gradually improved power information platform, are utilized to analyze the relations and trends of equipment state evolution from the perspective of inherent law of data itself. A big data mining analysis method is proposed for the condition assessment of equipments based on power operation and maintenance data. A data-driven personalized equipment condition assessment and fault prediction model is built, thus providing a new idea and technique for the sophisticated assessment and predication of the equipment state. The following aspects will be researched in the project:1)State assessment oriented multi-source (grid, equipment and environment) heterogeneous information feature analysis and data normalization modeling method;2)Methods of multi-scale anomaly detection on real-time data flow of power equipment state;3)Principle and implementation strategy of integrated learning on the pattern of power transmission equipment character, and dynamic assessment model of key performance of equipment based on big data samples;4)Multi-dimensional relation recognition methods applicable to the evolution analysis of power transmission equipment to build a data-driven relation analysis and fault prediction model.
