摘　　要：电力监控主机操作指令存在的异常点会影响电力监控主机操作指令的安全性,为了提升指令安全检测效果,提出高适配性的电力监控主机操作指令安全性自适应检测模型方法。该方法根据主机操作指令特性分析结果,利用建立的多模式无线数据采集设备采集电力监控主机操作指令数据;采用主成分分析(PCA)方法提取采集的指令数据特征,并在此基础上对指令数据实施降维处理,达到降低电力监控主机操作指令安全检测复杂度的目的;结合基于密度的聚类(DBSCAN)算法对提取的特征聚类,从中挖掘出异常点,基于挖掘结果构建自适应检测模型,利用该模型对挖掘的异常点检测,实现高适配性的电力监控主机操作指令安全性自适应检测。实验结果表明,通过对该方法开展检出率比较测试、检测时延比较测试,验证了该方法的可靠性高。The hidden abnormal points of operation instruction security adaptive detection model host affect the security of the operation instructions of the power monitoring host.In order to improve the security detection effect of the instructions,a highly adaptable detection model method of the operation instructions security of the power monitoring host is proposed.According to the analysis results of the host operation instruction characteristics,the method uses the established multimode wireless data acquisition equipment to collect the power monitoring host operation instruction data.The principal components analysis(PCA)method is used to extract the characteristics of the collected instruction data,and on this basis,the dimension reduction processing is implemented for the instruction data,so as to reduce the complexity of the security detection of the operation instructions of the power monitoring host.Combined with the density-based spatial clustering of applications with noise(DBSCAN)algorithm,the extracted features are clustered,and outliers are mined.Based on the mining results,an adaptive detection model is constructed.The model is used to detect the outliers mined,and the adaptive detection of the operation instruction security of the power monitoring host with high adaptability is realized.The experimental results show that the high reliability of this method is verified through the detection rate comparison test and detection delay comparison test.
