基于最小二乘支持向量机的绝缘子盐密光纤在线检测

本文介绍了利用光纤技术在线检测绝缘子盐密的基本原理,并在对受污石英玻璃棒和绝缘子进行试验研究的基础上,针对光通量衰减与盐密、环境湿度和尘埃比率之间复杂的非线性关系,利用最小二乘支持向量机,建立了以光通量衰减、环境湿度、尘埃比率等3个变量作为输入参数,等值附盐密度作为输出参数的智能预测模型,并通过部分实验数据验证了模型的有效性。最后应用预测模型开发了绝缘子盐密在线检测系统。

Insulator ESDD online detection based on least square support vector machine using fiber technology

In this paper,the basic principle of insulator salt density online detection using fiber technology is intro- duced.Based on laboratory simulation experiments of the contaminated silex sensor and insulator,aiming at the com- plicated nonlinear relationship between the luminous flux attenuation and various factors,the luminous flux attenua- tion,environmental humidity and ash density are chosen as three input variables,the ESDD is chosen as output vari- able,and an intelligent prediction model using least sq...
