Digital Intelligent Substation Virtual Loop Automatic Verification Technology Based on Weighted Least Square Method
In order to meet the demand of intelligent and efficient digital intelligent substation,an automatic virtual loop verification method based on weighted least square method is proposed.By improving the K-means clustering al-gorithm,the digital intelligent substation power equipment area is divided.The weighted least square method was used to integrate the relevant data of power equipment in each region.Make data flow rules between devices and analyze data flow of devices in each area.Through the keyword fuzzy matching method,the port information in the flow data is analyzed,and the virtual loop automatic check results of all areas are integrated to complete the digital substation virtual loop automatic check.Experimental results show that the maximum data variance of the fusion data is only 2.57,that is,the data variance is low and the data fusion accuracy is high.The anti-interference performance of automatic check is better.
