摘　　要：先进的传感技术和通信功能在改善量测和控制功能的同时,也使得配电网面临着各种可能的网络攻击。当攻击者通过特定手段篡改其他用户和自身量测记录,从而实现在维持总电量数据不变情况下的窃电行为,对于这种情况传统基于电量平衡的窃电监测方法难以有效识别。因此,基于智能电表量测数据的高阶统计信息,提出一种基于智能电表量测的配电网非侵入式窃电检测方法,实现对攻击发起方和受害方进行检测。实验证明,所提方法通过利用更高阶的用电量统计信息高效地检测到非侵入式攻击,并能够识别出所涉及的用户(攻击者和受害者),获得了理想的效果。While the advanced sensing and communication functions improve the measurement and control functions,the distribution network is also faced with various possible network attacks.When the attacker tampers with other users and their own measurement records by specific means,so as to achieve the electricity stealing behavior under the condition of keeping the total electricity data unchanged,the traditional electricity stealing monitoring method based on power balance is difficult to effectively identify.Therefore,on the basis of the high-order statistical information of smart meter measurement data,this paper proposes a non-invasive detection method of power larceny in distribution network based on smart meter measurement.It can detect the attacker and the victim.Experiments show that the proposed method can effectively detect non-invasive attacks by using higher-order statistics of power consumption,and can identify the users(attackers and victims)involved.
