摘要
提出的电力线相间短路点定距的方法是于故障传输线起端施加正弦信号，选取适当频率，使沿线分布的电压电流相量为自起端距离ｘ的函数，由起端故障测信－电压电流相量推知故障位置ｘｆ实现短路点定距。本方法的特点是检测信号的幅度与频率可调，可实现多频诊断，用于区分故障类型。
method for locating short circuit between two phases of a power line is presented in this paper. We exert a deteCting sinusoidal signal at the start of the post-faulttransmission line. By selecting a suitable frequency, voltage and current phasors distributing along the line become funCtions of x measured from the starting terminal of the line. The fault position Xf is derived according to the fault deteCting signal at the start, that is,short circuit position is located. It is the character of the method that the amplitude and frequency of the detecting signal is adjustable. Therefore, it may be used in multi-frequency diagnosisto distinguish fault types.
