Method for Monitoring the Status of Substation Control Cabinet Using Multi-Sensor Information Fusion Technology
摘要
Abstract
Real time sensing and monitoring of the status of the substation control cabinet can effectively prevent power outages,fires,and other situations caused by substation faults.Therefore,a method for monitoring the status of the substation control cabinet based on multi-sensor information fusion technology is proposed.The distribution map and adaptive weighting method are used to realize the data information fusion of the substation control cabinet with different sensors,so as to improve the accuracy of the status information after fu-sion.Wavelet packet decomposition is performed on the fused status information of the substation control cabinet,and the decomposition coefficients are reconstructed to extract key state features.The extracted state features are input into the least squares support vector ma-chine model to achieve monitoring and classification of the status of the substation control cabinet.The experimental results show that the fusion processing time of the proposed method for the information of the control cabinet is less than 45 ms,the accuracy of feature extraction is higher than 95%,and the monitoring information is basically consistent with the real information.The monitoring effect of the control cabinet status is good.关键词
