Analysis and Optimization of Double Confirmation Technology for Disconnector Position Based on Industrial Sensors

In order to achieve integrated regulation and provide a judgment basis for confirming the position of the switch after remote operation, it is necessary to install a dual confirmation device for the position of the switch in substations with high risk of remote operation. Mainly for substations with a voltage level of 220 kV and above, and substations with a voltage level of 110 kV and below that cause power grid safety accidents with a voltage level of three or above and significant and sensitive loads. This article analyzes and summarizes the advantages and disadvantages of the dual confirmation technology category for the position of industrial sensors. Based on the work case of installing a dual confirmation device for the position of the disconnector in the operation and maintenance center of our bureau, common problems with the dual confirmation technology for the position of the disconnector are optimized from the perspective of the operation profession. Finally, corresponding on-site control and disposal plans are proposed for the risk of remote operation in the dispatch.
