摘 要: 随着公共信息模型(common information model,CIM)在电力系统各应用中的不断发展,电力企业对CIM的扩展要求也日益急切。为实现配电网应用的“即插即用”,根据配电网的三相不平衡特性及特有设备,对CIM进行了三相属性、三相连接上的扩展,并将配电线路、调压器等特殊元件模型做了修改和扩充,实现了线路几何属性与电气属性的独立描述以及调压器的详细描述。最后采用面向对象语言Java和迭代器模式实现了36节点测试配电馈线的三相潮流计算,并保证了数据模型同前推回代算法的相分离,通过算例验证了扩展模型的准确性及应用的可维护性和可扩展性。

Abstract: With the development of CIM in power system application, the extension demand of CIM becomes more and more urgent. In order to implement “plug and play”, according to the character of unbalanced three-phase and some specific devices in distribution network, this paper proposed the three-phase connection and three-phase attribution extension of CIM. Some special components such as distribution line and voltage regulator were modified and extended. The geometric and electric attributes of line were modeled separately and the voltage regulator was presented in detail. Finally, using object-oriented language Java and iterator pattern, the three-phase power flow calculation of a 36-node distribution test feeder was implemented. The independence between data modeling and algorithm was implemented. The result validated the validity of the extension model and the maintainability and extensibility of the application.�
