The RTDS (real time digital simulator) simulations indicate that the method can find out the faulty line correctly.
試驗結果表明此方法可以準确地實現單相故障選線。
The other is to inject current. It selects the faulty line and realizes zero residual current based on concept of APF.
第二種方法即有源注入的方案,該方法選出接地故障的線路,借鑒有源電力濾波的理念來實現零殘流。
Results indicate that the method effectively raises the accuracy of faulty line detection for power system with small grounding current.
結果表明,該方法有效地提高了小電流接地選線的準确性。
First the zero sequence transient current signal sampled is enhanced, and then the signal enhanced is decomposed by using wavelet packet analysis to realize faulty line detection.
首先對采樣的零序暫态電流信號做增強處理,然後利用小波包分析方法進行故障選線。
The average correlation coefficient is calculated to remove the errors caused by asynchronous sampling and the faulty line selection list is sorted according to the fault probability of line.
通過求取相關系數平均值,避免數據采集不同步引起的計算誤差,得到按照發生線路故障可能性大小排列的故障選線序列。
在電氣工程領域,"faulty line" 指電力傳輸或配電系統中發生故障的線路。這種故障通常由絕緣失效、設備損壞、外部因素(如雷擊、樹木傾倒)或操作錯誤引起,導緻線路無法正常傳輸電能,并可能引發保護裝置動作(如跳閘)以隔離故障區域,保障系統安全和穩定。
核心含義與類型:
線路異常狀态:指線路因短路、接地、斷線或絕緣劣化等問題,偏離正常工作狀态。短路故障是最常見類型,包括:
專業影響:故障線路會引發:

“Faulty line”是一個複合詞,其含義需結合“faulty”和“line”的搭配來理解。以下是詳細解釋:
“Faulty line”主要用于技術場景描述故障線路,需與“fault line”(地質/經濟術語)區分。實際使用中需結合上下文判斷具體含義。
