摘 要: 根據(jù)10 kV 配電網的實際情況,就隨調式消弧線圈對配電網安全運行的影響進行系統(tǒng)的仿真計算,評估其優(yōu)缺點,并提出了一種消弧線圈的新型調諧方式:隨調式消弧線圈正常運行時預置40% 脫諧度。仿真結果表明,該新型調諧方式解決了目前系統(tǒng)廣泛應用的隨調式消弧線圈故障選線成功率低的問題,有利于配電網的安全可靠運行。
關鍵詞: 消弧線圈;欠補償;間歇性電弧接地;接地選線;評估優(yōu)化

Abstract: According to actual situation of 10 kV distribution network, this paper carried out the system simulation calculation for the impact of post-set arc suppressing coil on safety operation of distribution network and evaluated its advantages and disadvantages.This paper raised a new type of tuning method of arc suppressing coil. 40% detuning degree was preset in normal operation of postset arc suppressing coil. Simulation result shows that the new type of tuning method has solved the low successful rate problem of existing system widely applied in post-set arc suppression coil fault line selection, which is favorable for safety and reliable operation of distribution network.
