摘要
本文通过上海杨行、泗泾2座500kV变电站主变压器中性点串接小电抗器工程实例,介绍了目前正在华东电网推广的限制不对称接地短路电流一种新措施的技术特点,讨论了串接小电抗器后需注意的问题。
The paper taken two projects in Shanghai grid presents the use of small reactor connected to neutral of 500kV transformer to limiting unsymmetrical short circuit current which is now more and more used in east china power network and discuss the technique characteristic and mention some of the problems must be taken into account.
