| The research of this paper focuses on selecting fault-phase of high voltage power networks. The main contents are as following:1. Discussing the basic theories and the advantages and defects of all kinds of selecting fault-phase methods being in common use. To the current sequence component selecting fault-phase method based on comparing the phase of 70 and /2, the author detailedly analyzed and simulated the action properties and the existent problems under all kinds of fault conditions, and put forward the corresponding solutions.2. Developing a Power Network Fault Automatic Simulation Software. All simulation and analysis of this paper were processed with this software.3. With the cooperating among the current sequence component selecting fault-phase method, resistance selecting fault-phase method and voltage selecting fault-phase method, the author put forward a selecting fault-phase scheme of high voltage power networks, and fully simulated and demonstrated this scheme. |
