摘要
笔者研制了两种超高频传感器,引进了基于混频技术的信号调理技术,构造了基于AGA-BP神经网络算法的模式识别单元,设计了系统控制显示软件,最终形成完整的测量系统,最后通过变压器和GIS典型缺陷局部放电试验验证了系统性能。
An on-line monitoring system is constructed through developing two kinds of UHF sensors, designing a pattern recognition unit based on AGA-BP neural network algorithm, coding a program to control the system and display, and adopting the signal modulating technique based on frequency mixing. The system performance is verified with the experiments of partial discharge in transformer and GIS.
