Fuzzy Evaluation Method for the Operation Status of Secondary Equipment in Substation Automation Based on Digital Twin Technology
The evaluation of the operation status of secondary equipment in substation automation is often based on accurate equipment data,but the quality of the data is often affected by the substation environment,resulting in low accuracy of the equipment operation status evaluation structure.To alleviate this problem,a fuzzy evaluation method for the operation status of secondary equipment in substation automation based on digital twin technology is proposed.Using analytical methods to analyze the leakage magnetic induction intensity of the operating environment of sec-ondary equipment in substation automation,optimizing data quality through baseline correction,and based on this,map-ping the physical state of equipment using digital twin technology.By establishing a judgment matrix to determine the weight of the operating status parameters of secondary equipment,a two-level fuzzy evaluation system is construct-ed based on this.Through numerical tests,it can be seen that the evaluation results have high accuracy,meeting the analysis and operation requirements of secondary equipment status in substation automation.
