针对现有后备保护配合复杂容易误动的问题，基于广域测量信息，提出了一种新型故障判定算法。利用Petri网得到元件/IED关联矩阵，将方向元件动作信息作为故障判定的主判据，主保护以及距离I段保护的动作信息作为故障判定的辅助判据，将这两种判据与元件/IED关联矩阵通过矩阵运算结合在一起，最后得到故障位置信息。通过算例证明，该方法运算简单，容错性强，可实现快速故障判定。

@@@@Aiming at decreasing the probability of misoperation , a new algorithm of fault identification based on wide -area measurement information is proposed .The incidence matrix of component/IED is obtained based on Petri net .The primary criterion of fault identification is the action information of directional element , and the assistant criteria are the action informa-tion of main protection and the zone 1 of protection relay.The information of the fault position can be obtained by combing with these two criteria and incidence matrix of component /IED through matrix computation.The example verifies that the proposed method has an easy computation and a good fault tolerance , which can identify the fault quickly .
