The correct identification of the fault in the distribution systems can help in the healing process, system restoration, and thus lessen the duration of the outage. With the latest trend of penetrating the DG with the distribution network, the conventional fault identification (FI) methods become inappropriate for the promising active distribution network. Hence, the FI methods in the multisource, unbalanced, and weak distribution system is a challenge. In this article, the entire network is divided into the number of zones with each phase representing the two-port network. Further, the adjoint network matrices are formed for each of the two-port networks. The Tellegen's theorem based on adjoint circuit concept is then, used to identify the open-circuit section or the faulted node in the network using the input and output port information only. The voltage and current phasor information of the ports are acquired from the phasor measurement units based on the DFT. The methodology has been extensively verified on the IEEE-13 and IEEE-34 bus distribution systems integrated with the DGs, for all types of open and short circuit faults, with very encouraging results, with the real-time digital simulator.

基于PMU的基于TDS的基于不平衡主动配电网的基于Tellegen定理的故障识别方法

正确识别配电系统中的故障可以帮助恢复过程，恢复系统，从而减少停机时间。随着配电网渗透DG的最新趋势，传统的故障识别（FI）方法变得不适用于有希望的有源配电网。因此，在多源，不平衡和弱分布系统中的FI方法是一个挑战。在本文中，整个网络分为多个区域，每个阶段代表两端口网络。此外，为两个端口网络中的每一个形成邻接网络矩阵。然后，仅基于输入和输出端口信息，将基于伴随电路概念的Tellegen定理用于识别网络中的断路部分或故障节点。基于DFT从相量测量单元获取端口的电压和电流相量信息。该方法已在与DG集成的IEEE-13和IEEE-34总线配电系统上得到了广泛验证，并使用实时数字仿真器对所有类型的开路和短路故障均产生了令人鼓舞的结果。
