摘　　要：本文从故障口边界的一般形式出发 ,综合应用相序参数变换技术和广义戴维南定理 ,详细推导出一种计算电力系统复杂故障中故障端口电流的方法。文中算法采用故障类型导纳参数模型 ,不但解决了任意过渡电阻的故障计算问题 ,还省去了程序实现中根据故障类型存储、检索故障类型导纳参数的步骤 ;相较于阻抗参数模型 ,算法更通用、简便。较好地解决了电力系统中具有任意不对称过渡电阻的简单故障及复杂故障计算的通用性问题。算例表明 。Based on the phase sequence parameter transformation technique and the multi-dimensional Thevenin theorem, a new method for calculating port current in complex fault of electric power system is presented in detail in this paper. This method adopts the fault admittance matrix, which not only solves the fault calculation with different transition resistance but also releases the works searching and storing the fault admittance matrix; Comparing with the fault impedance matrix , it is more generalized and simpler. The method is suited to all kinds of simple fault and complex fault, and also suited to various faults with different fault transition resistance. It has been proved to be accurate by a numerical example.
