Application Research on Natural Frequency Method in Single Terminal Traveling Wave Fault Location

摘要：

　　A method is provided to make natural frequency method be applied to single terminal traveling wave fault location in the paper.A group of fault distance suspected is calculated by single terminal method of traveling wave fault location method firstly,then deal with current travelling wave of fault by FFT to get the natural frequency reflecting fault location so that a fault distance can be calculated by it.Contrast the fault distance from natural frequency method and everyone of the group of fault distance suspected from single terminal method of traveling wave fault location method to determine the suspected fault distance closed to it is the calculation results we want.Numerical simulation shows the method can improve effectively the reliability of single terminal traveling wave fault location.
