Power transmission device state evaluation and risk analysis method and device based on multidimensional data

Abstract

The invention provides a power transmission device state evaluation and risk analysis method and device based on multidimensional data and relates to the technical field of meteorological and electric power technology application. The method comprises steps of: acquiring and storing information data of a PMS production management system, information data of a power transmission and transformation monitoring system and information data of a meteorological bureau system through multidimensional heterogeneous data access; carrying out data preprocessing on the information data of the power transmission and transformation monitoring system and generating online monitoring effective data of a power transmission circuit; determining a power transmission device evaluation index according to the information data of the PMS production management system and the online monitoring effective data of the power transmission circuit, and determining an evaluation state corresponding to the power transmission device evaluation index according to a preset state evaluation strategy; and determining a risk index of the power transmission device according to the information data of the meteorological bureau system, the asset value of the power transmission device, the asset loss value of the power transmission device and the average fault rate of the power transmission device. According to the invention, the multidimensional data is comprehensively considered.

Description

technical field [0001] The invention relates to the technical field of meteorological and electric power technology applications, in particular to a method and device for state evaluation and risk analysis of power transmission equipment based on multidimensional data. Background technique [0002] In recent years, with the vigorous development of smart society and the continuous advancement of smart grid operation and maintenance in various grid provinces, not only various grid monitoring systems have generated a large amount of historical equipment operation data, equipment historical fault data, equipment historical defect data, wildfire Monitoring data, lightning monitoring data, wind deviation monitoring data, micro-meteorological monitoring data and other grid field system data. At the same time, other grid-related industry data application systems also generate satellite remote sensing data, meteorological data, lightning data, wind data and other meteorological profes...
