摘　　要：提出了电力系统发生复杂故障时快速计算互感支路电流的新方法。作者利用虚拟节点的思想,推导出既适于简单故障又适于复杂故障的计算互感支路电流的通用公式。该方法物理概念清晰、原理简单、计算过程中不需修改故障所在支路导纳矩阵,计算过程变得简便快捷。它不仅适用于一般复杂故障的计算,还适用于包括同杆多回线跨线故障在内的复杂故障计算。Based on the idea of dummy node, this paper presents a new generalized method to calculate mutual-inductance branch current for complex fault in power system. The branch admittance matrix has not to be modified and its principle is very simple in the method. It is suited to be used not only in general complex fault but also in the complex fault including interline fault in power system.
