Analysis and discussion of 10kV protection setting calculation in 220kV substation
摘要
以太子庙 2 2 0 k V变电站为例
对主变压器 1 0 k V侧限时速断、 1 0 k V出线电流速断定值整定计算中存在的一些问题进行了分析与探讨
并提出了相应的建议。
Abstract
Taking the Taizimiao 220kV substation for instance
this paper analyzes and discusses some problems existing in fixed setting calculation of both main transformer 10kV side time quick-break and 10kV line current quick-break. Some suggestions are also discussed in this paper.
