乌海配电网接地方式的研究
|
摘要
本文对乌海配网系统中性点的接地方式进行了研究,归纳出乌海配网不接地系统及现有消弧线圈接地系统的不足。在对乌海配网系统现运行消弧线圈全面分析的基础上,通过研究消弧线圈的作用和影响熄弧的主要因素,提出采用自动跟踪补偿和连续无级调节消弧线圈的观点;通过研究磁阀式消弧线圈工作原理及其特性,确定采用磁阀式自动跟踪补偿消弧线圈的接地方式。经过现场人工试验和投入运行,结果表明磁阀式消弧线圈能够克服现有消弧线圈的不足,实现全自动测量线路容抗及接地补偿的功能。
The deficiencies about ungrounded supply system and earth neutral system with extinction coil, which existing in Wuhai power network, are summarized via researching grounding fashions of this network in this paper. With the foundation of muti-analysis about the extinction coil running in Wuhai power system and the researches about the role of extinction coil and primary factors of effecting extinguishing arc, the viewpoint about adjusting extinction coil via automatic following compensation and continuous stepless is brought. The grounding fashion which via extinction coil with magnetic valve type is confirmed based the researches of operating principles and characteristic of extinction coil with magnetic valve type. It was put to test and run at Wuhai power network, the result is indicated that the extinction coil with magnetic valve type can overcome the shortage brought by the extinction coil in existence and it can implement the foundations of automatically measuring line reactance and recouping via grounding.
