提出了在线潮流研究中外部系统的等效模型。的主要贡献是一个简单的扩展沃德型等效方法，解决了边界总线指定问题，并给出可靠和准确的结果。该方法可以同样适用于离线等值，它克服了缓冲区的需要。这种技术的变化进行了研究。该模型需要拓扑信息，但不需要外部系统的实时测量数据。在IEEE30和118节点潮流试验系统和S.E.的835节点互联15GW电力系统上进行了仿真验证。巴西
Equivalent models for the external system in online load-flow studies are presented. The main contribution is a simple extension to the Ward-type equivalencing method that solves the boundary-bus designation problem and gives reliable and accurate results. The method can be applied equally well for off-line equivalencing, where it overcomes the need for buffer zones. Variations on this technique are investigated. The models require topology information, but no real-time measurement data, for the external system. The new methods have been verified by simulation on the IEEE 30 and 118 bus load-flow test systems and on the 835-bus interconnected 15 GW power system of S.E. Brazil.
