摘要
变压器纵联差动保护构成的原理具有较大的近似性,而且部分保护参数具有不确定性。针对目前变压器纵联差动保护应用中的特点和现状,提出优化变压器纵联差动保护动作参数和动作逻辑的具体办法,经现场运行和具体事故分析,表明可以提高变压器纵联差动保护的运行水平。
The theories of the transformer pilot differential protection are of similarity and the part of protection parameters are of uncertainty. According to the characteristic and present state of the transformer pilot differential protection, this paper puts forward its optimizing action parameter and action logic method. Practical operation and fault analysis verify that the method can advance the running level of the transformer pilot differential protection.
