摘要
在分析现有各种变压器励磁涌流识别算法的基础上 ,采用模糊集合理论 ,综合各判据的优点 ,得到一种较为理想的新算法 ,通过EMTP仿真计算 ,并考虑CT传变特性后 ,该模糊多判据算法能快速识别各种变压器内部故障和励磁涌流情况 。
After analyzing the schemes of transformer protection in existence,we present a new algorithm based on fuzzy set theory,which integrates the merits of all the other rules. All principles are verified by the EMTP,the result shows that the new algorithm is useful and can discriminate the inrush and fault current not only quickly, but also reliably.
