In order to satisfy some requirement , the device can locate the fault using single - terminal data 同时为了满足某些需要,测距装置也提供单端测距功能。
Because conventional single - terminal method of fault location ca n ' t eliminate the influence of fault resistance and the remote in - feed , its utility is limited 单端测距法由于存在难以消除过渡阻抗和对端系统阻抗的影响这一缺陷,使其应用受到限制。
Only using data of single - terminal , the algorithm can eliminate the influences of the fault resistances and it need n ' t resolve the complicated equation of long line 这种方法仅采用线路的单端数据,不受故障过渡电阻的影响,无需求解复杂的长线方程。
This thesis presents a single - terminal fault location technique that is used together with recloser . the technique takes advantage of reclosing of single - terminal recloser to eliminate the influence of the remote source impedance . a distributed parameter line model is used for the proposed algorithm , thus the technique can be used in hv transmission line 为了克服这一缺点,本文提出了与自动重合闸配合使用的单端故障测距方法,根据电力系统的运行特点,利用故障线路在试送电时自动重合闸的单端重合状态来消除对端系统的影响,测距算法建立在分布参数模型基础上,使其可应用于高压输电线路。
