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(diǎn),本文提出了與自動(dòng)重合閘配合使用的單端故障測(cè)距方法,根據(jù)電力系統(tǒng)的運(yùn)行特點(diǎn),利用故障線(xiàn)路在試送電時(shí)自動(dòng)重合閘的單端重合狀態(tài)來(lái)消除對(duì)端系統(tǒng)的影響,測(cè)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(xiàn)路。
