摘　　要：在对较为复杂的大型电力网络进行计算时,对其中和研究目的关联较弱的部分进行有效地网络等值可以大大缩减工作时间和工作量。电力系统仿真软件PSS/E主要通过对研究系统影响较小的外部系统的导纳矩阵进行降阶简化实现对系统的网络等值,利用PSS/E对网络等值使用算法进行了研究,通过一算例对其潮流计算和稳定计算进行了仿真验证,经等值后的系统能反映原系统的主要特征,有良好的动态等值精度。并且对使用PSS/E进行网络等值过程中遇到的问题进行了分析。In the calculation of more complex and large power networks, the network equivalence of part which is weaker effective to the research system can greatly reduce working times and workload. To realize the network equivalence with PSS/E, the admittance matrix of external system, which is smaller affective to the research system, is reduced. The algorithms of the network equivalence are studied by PSS/E, and its power flow calculation and stability calculation is simulated through an example. The results show that an equivalent system can reflect the main features of original system , and has a good degree of accuracy in dynamic equivalent. Finally, the problems existed in implementing the network equivalence with PSS/E are analyzed.
