摘　　要：潮流转移识别是避免远后备保护不合理动作的必要手段。文中阐述了基于广域信息识别潮流转移的原理,分析了故障动态过程对潮流转移识别的影响,并指出了基于广域信息识别潮流转移立足于最终结果的局限性。同时分析了非故障线路在某些故障情况下被不合理切除的案例,探讨了结合本地信息识别潮流转移的必要性,并指出了下一步的研究方向。Flow transferring identification is one of the necessary means to prevent unreasonable actions of remote backup protection. The principle of flow transferring identification based on wide-area information is described. The impact of fault dynamic process on flow transferring identification is analyzed. The limitations for flow transferring identification based on wide-area information are recognized. Some cases which induce non-fault transmission lines mistakenly removed are analyzed. The necessity for flow transferring identification based on local information is discussed and the direction for future research is given.
