Analysis of Fault Dynamic Process Impact on Flow Transferring Identification

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.
