In order to solve the problem of large losses caused by transmission line operation faults to the power grid,a trans-mission line operation fault analysis system is designed.The transmission line operation state is automatically detected by using a movable fault detection device,and the video monitoring platform is intelligently improved by using image processing technol-ogy and pattern recognition technology,so as to realize the real-time monitoring of the transmission line operation state.The collected transmission line operation image data are transmitted to the monitoring master station platform,and the transmission line operation fault diagnosis is realized by using the algorithm of variational modal decomposition and permutation entropy.The experimental results show that the effectiveness of the system in image monitoring of fault detection device is as high as 96％,and the accuracy of fault analysis is as high as 98％.
