| Abstract: | Based on compensation method, a unified model to calculate the faults for the setting of protective relayings is established. On this basis, according to the superposition theory and the reciprocal theory, a versatile method to calculate faults for protective relaying setting is presented. Using the presented method, the calculations for any kind of fault in protective relaying setting can be completed without modifying the nodal impedance parameters of the original network. This method possesses following features: (1) adaptable to network changes in topology and very fast fault calculation speed; (2) all kind of faults for setting protective relays can be calculated in the same way and (3) easy to program. |
