【Abstract】 Diakoptics for the transient response of the coupled multiphase transmission lines, based on the equivalent circuit model is studied.At any time interval, the equivalent circuit model of transmission lines is divided into some sub-circuits, which are substituted by multiport dynamical source model. The equivalent sub-circuit model in discrete domain is formed for numerical simulation and the equivalent model of the coupled multiphase transmission lines is then proposed in discrete domain.The number of the variables in the proposed model is the product of its phase number and the sub-circuit number. The variables can be directly expressed without any iteration. After solving the variables of the discrete domain model of transmission lines, the transient response of transmission lines can be obtained through calculating the inner variables of sub-circuits in parallel.The proposed method is simple and is certified to be an effective method to analyze the transient response of transmission lines.更多还原
