Abstract :
The paper proposes a method to identify bus split by innovation graph technique. The branch/bus model is utilized in the method. Every possible splitting bus is selected as suspicious bus based on the large magnitude of innovation elements of the branches connecting to the bus. The method first determines the split mode of suspicious bus and then identifies the true bus split, after analyzing the innovation characteristic existing in splitting bus. The advantage of this method is lower measurement redundancy requirement and simpleness in calculation. The example of IEEE-30 bus system demonstrates that this method can identify bus split, and the method can identify the multi topology error situation when branch topology error and bus split take place simultaneously.
