摘　　要：介绍同杆双回线复杂故障的精确计算方法。采用了精确的分布参数模型和多次叠加的算法,将分布电容和线路换位的影响计算在内从而精确地计算同杆双回线复杂故障下的工频电量。文中以单线接地后故障线的一侧断路器断开后的复杂故障为例阐明了该算法的原理。An accurate calculation method for complex faults of double power lines on the same tower is introduced. By precise model of distributed parameter and repeated adding method, considering the effects of power line transposing and distributed capacitance, the calculation method can precisely get complex fault results of double power lines on the same tower. By example of one line to ground fault and cutting off by one side of breaker, the paper illustrates the principle of this calculation method.
