摘要
介绍了一种采用电磁场建模仿真类软件通过储存的能量求解变压器短路阻抗的方法。将此方法与常规计算方法的结果进行对比,证明其具有更高的准确性。同时,利用这种计算方法可以解决一些常规解析计算方法难于计算阻抗的特型变压器或电抗器的设计及现场多绕组变压器在不同工况下运行时变压器阻抗的计算评估问题。
A method by using electromagnetic field simulation analysis software which can calculate the transformer short-circuit impedance from stored energy is introduced.Comparing with the results of conventional calculation method,this method can obtain more accurate short-circuit impedance.Furthermore this method can not only be used to get the short-circuit impedance of special transformer or reactor,which is diffcult to be obtained using conventional calculation method,but also be used to calculate and evaluate the short-circuit impedance of multi-winding transformer in different feld running conditions.
