    摘 要: 介紹了變壓器傳統抗短路能力校核方法的不足,提出了一種計及試驗與運行信息的變壓器抗短路能力校核新方法。該方法以傳統的設計計算校核為基礎,增加試驗信息與運行信息對設計校核結果進行修正,實現變壓器抗短路能力的動態校核。經實際算例驗證表明,新方法更容易發現系統薄弱環節。
    關鍵詞: 抗短路能力;設計校核;短路阻抗;頻率響應;運行參數

    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
