Power Network Branch Parameters

This chapter describes algorithms for network parameter estimation and detection/identification of possible errors. The concepts of irrelevant branches and barely relevant branches are adopted. The parameter error processing performed by methods that explore these concepts is based on thoroughly chosen recorded measurement scans in which redundancy is sufficiently high. Considered a matter of great significance for improving the reliability of SE results, this functionality can also be a way of cleaning the network parameter database shared by all EMS applications. A didactic example of the parameter estimation problem using the irrelevant branch method is presented. Advanced topics on the subject are pointed out. Proposed problems are included, and a list of references is provided.
