摘　　要：在野外恶劣环境中,密集输电通道安全性难以保证,降低了输电网的工作可靠程度。为了保证密集输电通道安全、及时风险干预,进行基于多维信息特征映射的密集输电通道信息物理风险演化仿真研究。在野外现场布设一体化环境监控系统,采集密集输电通道信息物理风险多维影响因素,并利用主成分分析法从影响因素中选取多维信息主特征。构建主特征与风险等级之间的多维信息特征映射模型,得出风险值,对比等级划分表,判断密集输电通道信息物理风险程度。结果表明:6 d前密集输电通道信息物理风险值均处在0以下,但总体呈现上升趋势,该阶段为风险发生前;在6 d之后,风险值进入低风险区域;在之后14 d,风险值分别经过了低风险、较低风险、中风险,最终停留在了较高风险区域。为保证密集输电通道安全提供了新的研究思路。Affected by the harsh environment in the field,it is difficult to ensure the security of dense transmission channels,which reduces the reliability of the transmission network.In order to ensure the security of dense transmission channels and timely risk intervention,the simulation research on information physical risk evolution of dense transmission channels based on multidimensional information feature mapping is implemented.An integrated environmental monitoring system is set up in the field to collect multidimensional influencing factors of physical risk of dense transmission channel information,and the principal component analysis method is used to select the main features of multidimensional information from the influencing factors.A multidimensional information feature mapping model is built between the main features and the risk level.It can get the risk value,compare the level classification table,and judge the information physical risk degree of dense transmission channels.The results show that the information physical risk values of dense transmission channels are all below 0 before 6 days,but the overall trend shows an upward trend.This stage is before the risk occurs.After 6 days,the risk values enter the low-risk area.After 14 days,the risk values pass through low risk,lower risk and medium risk respectively,and finally stays in the high-risk area.It provides a new research idea to ensure the security of dense transmission channels.
