摘要
为避免在故障计算和分支计算时对全网阻抗矩阵元素进行计算,文章采用补偿法并通过加入补偿电流的概念,只对部分支路进行修正,使浮点运算工作量减少了三分之二,大大提高了整定效率。
During the fault calculation and branch coefficient calculation the compensation algorithm is used to avoid the calculation of impedance matrix elements of the whole network. After adding the compensating current only partial branches are needed to modify. Using this method the floating point operation is reduced by two-third and the setting efficiency is considerably improved.
