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 為了克服這一缺點,本文提出了與自動重合閘配合使用的單端故障測距方法,根據(jù)電力系統(tǒng)的運行特點,利用故障線路在試送電時自動重合閘的單端重合狀態(tài)來消除對端系統(tǒng)的影響,測距算法建立在分布參數(shù)模型基礎(chǔ)上,使其可應(yīng)用于高壓輸電線路。
