摘　　要：电力网络拓扑分析是对实际电力网络复杂电气接线的简化过程,是进行计算分析的基础。根据企业电力系统离线应用的特点,在CIM模型基础上,引入触点的概念,建立了适用于企业电力系统图形化电网建模的电气连接模型,提出了详细描述电气设备实际连接关系的连接线表示法。将所有电气上零阻抗连接的设备(或端点)聚合在一起,形成拓扑节点;然后利用拓扑节点与设备的关联关系,将所有电气上连通的设备(或端点)聚合在一起,形成拓扑岛。结合企业内部电力系统与外部电网的不同接入方式,分析了该方法在企业电力系统离线分析中的典型应用。算法分析和算例表明,该方法逻辑简单、结构清晰、结果信息丰富,适用于企业电力系统离线应用。Power network topology analysis is a process for simplifying complex electrical connection and is the basis for calculation and analysis.According to the characteristics of enterprise power system off-line application,based on the CIM model,the concept of port is introduced,and an electrical connection model is established,which is suitable for electric power enterprise graphical modeling.A link method detailing the actual connection of electrical equipments is proposed.All electrical zero-impedance connected devices(or terminals)are merged for a topological node;then all electrically connected devices(or terminals)are merged for a topological island,using the relationship of topology node and device.Combined with the different access of enterprise internal power system into the external power system,the typical applications of this method in enterprise power system off-line analysis are analyzed.Algorithm analysis and examples show that the method is simple in logic,clear in structure,and rich in information.It is applicable to enterprise power systems off-line application.
