طرح خطای خطوط برای خطوط انتقال چند ترمینال با استفاده از اندازه گیری های غیر همزمان

In this paper, a simple alternative fault location algorithm for multi-terminal transmission lines using unsynchronized measurements is proposed. The developed data synchronization procedure is employed to identify the faulted leg before the fault location is calculated. The fault location algorithm is independent of the fault resistance and source impedance variations. The proposed faulted leg identification and location algorithm is extensively tested for all major fault types and different high fault resistances. The results show that the proposed multi-terminal fault location algorithm is fast, accurate and immune to power system transients.
