A Fast Searching Scheme for Power Flow Transferring Identification in Complex Power Grid

Abstract:

Power flow transferring random occurred in power grid, so how to quickly identify overload line is a key problem to prevent cascading trips. This paper according to the bus self-impedance change rate rapid search the area which possible happened power flow transferring, and through the correction method for network equations checked the lines in this area whether overload or not, then selected the overload line caused by power flow transferring. Under the condition of known initial network parameters, this scheme according to the local network parameters modified to related calculation, improves the calculation speed, and has advantages for multipoint flow transferring recognition in complex power grid. Taking the New England 10-unit 39-bus system which also used this method as the example, in this case, this method is confirmed by the BPA simulation.
