Analysis and Improvement of the Power Flow Transferring Identification Method Based on DC Sensitivity Factors

Abstract:

Research on the power flow transferring identification method based on DC sensitivity factors is carried out. According to the analysis of transfer power flow sensitivity factors matrix, the disadvantage of this method is proposed that it may identify incorrectly due to the only criterion of active power when fault occurs. In order to improve its performance, the criterion of impedance angle is put forward. The combination of the two criteria is applied to the improved flow transferring identification scheme. The improved scheme can identify non-faulted overload reliably and block zone 3 distance protection to prevent cascading trips effectively. The simulation results of IEEE 10-machine 39-bus system have proved its superiority and practicality.
