Research on Secondary Error Prevention Technology in Smart Substation
A smart substation secondary error prevention system was designed to address the issue of mis-operation during the state transition process of secondary equipment.Error prevention system using DC systems,station low-voltage system,monitoring system,secondary control circuit,microcomputer protection device,measurement and control device,and metering device were built;applying fusion model based on SVM and PCA algorithm,the real-time monitoring of the status parameters of primary and secondary equipment in substation was achieved;the parameters of secondary equipment in the substation were analyzed.The experimental results indicate that the accuracy of secondary error prevention through the system can reach over 90％,which lays the foundation for further research.
