摘　　要：提出了一种新的节点负荷阻抗模的求取方法,利用广义Tellegen定理求取节点负荷阻抗模对网络参数的灵敏度,对节点负荷阻抗模进行修正,避免了大量的潮流迭代计算。实例证明,该方法在保证准确性的同时加快了求取的速度。A new method of calculating load equivalent impendance module was proposed. The sensitivity of the load impendance at the nodal to network＇s parometers was calculated and found by using Generalized Tellegen＇s Theorem. And amendment was made to the load impendance module, avoiding lots of flow calculation. Examples proved that on the premise of guaranteeing accuracy, the method in this paper can decrease the work of calculation and improve the calculating speed.
