Xueqiong Wu, Fan Zhang, Lei Chen, Weiyan Zheng · 2020
The distribution network of the city is connected to the main network and the power users, The stable operation of the distribution network is related to the stable operation of the whole power system, It is of great practical significance to evaluate the urban distribution network and identify the weak link of the power grid. From the actual situation of the intelligent distribution network, this paper focuses on the intelligent distribution network risk assessment and safety early warning mechanism. From the structural characteristics of intelligent distribution network, equipment running status and environmental factors characteristics, this paper makes use of probability analysis, data mining, information fusion technology and other methods, the risk evaluation index system and the risk index quantification calculation model are established to analyze the potential risks and the extent of damage to the intelligent distribution network.
