本文提出了一种面向配电台区部署的智能配变终端的安全态势评估方法,针对台区智能配变终端台区管理、边缘计算等功能,分析该终端面临的主要安全问题,提取影响到终端安全的关键系统指标,基于信息熵的数学模型,构建了终端安全态势评估的随机森林数学模型。通过构造仿真算例,对该评估方法进行了计算分析,并基于算例构造的随机森林模型对本文提出的评估方法进行验证。结果表明,所提出的方法对于终端异常的工作指标能够实现准确识别和分类,从而实现安全态势评估,具有一定的实用价值。

This paper presents a security assessment method for intelligent distribution transformer terminal unit(TTU). Facing the applications of management and edge computing of distribution station area,the main security problems faced by the terminal are analyzed, and the key system indicators affecting the terminal security are extracted. Based on the mathematical model of information entropy,a stochastic forest mathematical model for terminal security situation assessment is constructed. By constructing a simulation example,the evaluation method is validated by the stochastic forest model. The res...
