Reliability evaluation of electric railway catenary based on data mining

The reliability evaluation results of electrified railway catenary directly affect the normal operation of electrified railway. The traditional reliability evaluation methods of electrified railway catenary have some defects, such as large error and low evaluation efficiency. In order to improve the accuracy of reliability evaluation of electrified railway catenary, a reliability evaluation model of electrified railway catenary based on data mining is proposed. Firstly, the current domestic and foreign research status of catenary reliability evaluation for electrified railway is analyzed, and the limitation of various catenary reliability evaluation models for electrified railway are pointed out. Then, the historical data of catenary reliability evaluation foe electrified railway are collected, and the reliability evaluation model of catenary for electrified railway is established for electrified railway are collected, and the reliability evaluation model of catenary for electrified railway is established by data mining technology. Finally, specific examples are used to electrify the catenary. The validation test of the reliability evaluation effect of railway catenary shows that, compared with the traditional reliability evaluation model of electrified railway catenary, this method can better reflect the changing trend of reliability evaluation model of electrified railway catenary, this method can better reflect the changing trend of reliability of electrified railway catenary. The accuracy rate of reliability evaluation of electrified railway catenary has been significantly improved. At the same time, the modeling process of reliability evaluation of electrified railway catenary uses shorter time, the reliability evaluation efficiency of electrified railway catenary.
