摘要

提出了一种新的基于α平面的双回传输线负序交叉差动保护算法。为了验证该算法的有效性，利用ATPDraw软件对一条230 kV、200 km长的双回输电线路进行了故障模拟，对算法的性能进行了评价。结果表明，该算法对线路两端的非对称故障都能提供可靠、快速的运行，同时保证了外部故障的安全性，是提高双回传输线保护的一种很有前景的替代方案。

A new negative-sequence cross-differential algorithm for double-circuit line protection

This paper proposes a new alpha plane-based negative-sequence cross-differential protection algorithm for double-circuit transmission lines. To demonstrate its usefulness, the algorithm’s performance was evaluated through faults simulated in a 230 kV, 200 km long double-circuit transmission line using ATPDraw. The results reveal that the proposed algorithm provides a reliable and fast operation for asymmetric faults on both circuits of the line, as well as ensuring security for external faults, revealing it as a promising alternative for improving double-circuit transmission line protection.

期刊介绍： Electric Power Systems Research is an international medium for the publication of original papers concerned with the generation, transmission, distribution and utilization of electrical energy. The journal aims at presenting important results of work in this field, whether in the form of applied research, development of new procedures or components, orginal application of existing knowledge or new designapproaches. The scope of Electric Power Systems Research is broad, encompassing all aspects of electric power systems. The following list of topics is not intended to be exhaustive, but rather to indicate topics that fall within the journal purview. • Generation techniques ranging from advances in conventional electromechanical methods, through nuclear power generation, to renewable energy generation. • Transmission, spanning the broad area from UHV (ac and dc) to network operation and protection, line routing and design. • Substation work: equipment design, protection and control systems. • Distribution techniques, equipment development, and smart grids. • The utilization area from energy efficiency to distributed load levelling techniques. • Systems studies including control techniques, planning, optimization methods, stability, security assessment and insulation coordination.
