摘　　要：在计算小步长网络模型时,RTDS实时数字仿真系统受到网络节点个数的限制。分相封装建模方法,可有效的克服这一弊端。基于上述思想,本文搭建了3种链式SVG的RTDS网络模型:即基于传统的大小步长接口进行分相封装SVG网络模型;小步长传输线作为滤波器的分相封装SVG网络模型,以及A相、B相、C相完全对称的分相封装SVG网络模型。分析比较上述3种SVG网络模型的特点,研究结果可作为链式SVG实时数字仿真建模的依据。In case of calculating small step network model,RTDS real time digit simulation system is limited to the number of network node. Such trouble can be overcome effectively by the single phase encapsulation modeling. On the basis of above idea,three kinds of SVG RTDS network modes are set up： That is the single phase encapsulation SVG network model based on traditional big and small step interface, Single phase encapsulation SVG network model with small step transmission as filter;and single phase encapsulation SVG network model with phase A, B and C symmetrical completely. The features of above three kinds of SCG network models are analyzed and compared. The study result can be used as base for cascade SVG real time digit simulation and model.
