摘 要: 介绍了变压器传统抗短路能力校核方法的不足,提出了一种计及试验与运行信息的变压器抗短路能力校核新方法。该方法以传统的设计计算校核为基础,增加试验信息与运行信息对设计校核结果进行修正,实现变压器抗短路能力的动态校核。经实际算例验证表明,新方法更容易发现系统薄弱环节。

Abstract: Introduction was made to the insufficiency of traditional transformer anti-short-circuit capacity checking method. This paper raised a new method of transformer anti-short-circuit in consideration of test and operation information, which took the traditional design calculation checking as the basis, adding test and operation information to carry out amendment for design checking result, to realize dynamic checking of transformer anti-short-circuit capacity. The actual calculation examples verify that the method is easier to find system weak links.
       Key words: anti-short-circuit capacities; design checking; short-circuit impedance; frequency response; operating parameter
