摘要
变压器主保护均采用差动保护,其关键问题是要求能区别开正常的励磁涌流和内部故障电流。笔者提出一种新的算法,创建了平衡牵引变压器保护的模型,并在此基础上提出了一种新的平衡牵引变压器保护原理。
The transformer main protection uses the differential motion protection, its key question is the request can distinguish the normal excitation to flow rapidly with the internal fault current. The author proposed that one kind of new use least squares method's algorithm, and founded has towed the model which balanced the transformer protected. Based on this proposed one kind of new balanced hauling transformer protection principle.
