Abstract

The invention discloses a voltage and current acquisition assembly based on a distribution automation fusion switch, and particularly relates to the technical field of assembly working state recognition algorithm research. Data sampling abnormity caused by problems of a power grid is eliminated through a terminal topological relation in the power distribution network, and meanwhile, whether a component is damaged or loosened is judged through 288-point sampling data characteristics, so that accurate maintenance information is provided for operation and maintenance personnel of a power system, and the maintenance efficiency is improved. Considering the influence of the distribution automation terminal on the accuracy and reliability of a sampling assembly in the field installation environment and the operation age limit, the current and voltage sampling assembly of the distribution automation primary and secondary fusion switch is subjected to abnormal identification and timely defect elimination, so that the effective perception of the distribution network is realized, and the accuracy and reliability of the distribution automation terminal are improved. And effective basic data support is provided for reliable operation of the power distribution network.

Description

technical field [0001] The invention relates to the technical field of component working state identification algorithm research, more specifically, the invention relates to a voltage and current acquisition component based on a distribution automation fusion switch. Background technique [0002] State Grid Sichuan Electric Power Company has installed a large number of primary and secondary fusion switches in the process of distribution automation construction, and the terminal access has reached tens of thousands. The primary and secondary fusion switches provided by distribution network automation manufacturers are uneven, with various types. The operating time span of the equipment is relatively large, and there are differences in the software and hardware of the equipment. [0003] At the initial stage of distribution automation construction, the installation terminal has not been fully inspected. At the same time, as the installation and operation time becomes longer an...
