Abstract


Cyber physical fusion enhances the coupling effect and influence of primary and secondary equipment in distribution network. In order to reflect the overall operating state of pole-mounted switch, this paper proposes the secondary equipment state indexes and other indexes, based on the current on-line monitoring index system. Then with fuzzy comprehensive evaluation and bidirectional weighing method, the result of condition assessment can be obtained. When determining weight, the deterioration of data taken from a certain single equipment in a certain period of time is analyzed by the entropy weight method, which highlights the index with obvious deterioration of specific equipment at specific stages. Moreover, the data deterioration weights are combined with the index importance weights. Finally, the accuracy of the condition assessment method is verified in the calculation of a specific example
