Automated Calculation and Coordination of Protective Relay Settings

详细

Development of new methods of automated coordination of traditional step-type protection and multidimensional protection based on statistical principles is necessary for creation of an effective system of relay protection for advanced power supply systems with a complex topology. A graphical-analytical method is proposed for automated calculation of the settings for multidimensional protection based on the matrix representation of the set of protection and protection zones, and an example calculation is given.
