330kV花园变人工接地网改造设计的理论核算

Theoretical Accounting of Improvement Design about Manual Earth Network in 330kV Huayuan Substation

文章结合 330kV花园变人工接地网的改造工程 ,对相关的设计思路进行了理论性阐述。由于青海电网内人工接地网的改造 ,特别是大型及高电压等级变电站人工接地网的改造设计尚属首次 ,因此文章得出的结论对于提高青海电网人工接地网的建设质量和运行可靠性具有一定的参考价值。

It is the first time for Qinghai power network to improve the manual earth network, especially in high-voltage substation, so the paper proposes theoretical discussion of improvement design about manual earth network in Huayuan substation , and obtains some stressed factor for Qinghai manual earth network improvement.
