基于CIM的配电网模型到RTDS仿真模型的转换研究
|
摘要
利用配网管理系统中基于CIM的配电网配置信息直接在RTDS中生成仿真模型,可以快速地构建配电网实时仿真模型并减少人为误差。在讨论CIM和RTDS模型的区别以及对应关系的基础上,分析了基于CIM的配电网模型转换到RTDS仿真模型的若干关键技术。在拓扑转换过程中提出了基于生成树的坐标位置生成法,在此基础上针对闭合环多且集中的拓扑电路提出了基于最小独立闭合环的方法,并用连枝比和分散度两个评价指标来判断适用于后者的电路拓扑。最后开发了相应模型转换软件,利用软件将一个真实的配电网转换到RTDS仿真系统中,从而进行了有效性验证。
In order to quickly construct the real-time simulation model of the distribution network and reduce the human error, it is necessary to study the method of converting the CIM-based distribution network, which comes from DMS, into RTDS simulation model. After discussing the difference and relationship between CIM and RTDS model, a number of key technologies of automatic conversion from the CIM-based distribution network to RTDS simulation model are proposed. In the process of topology transformation, a method of generating coordinate position based on spanning tree is proposed. On this basis, a method based on minimum independent closed loop is proposed for closed loop and concentrated topology circuit. And two evaluated indicators, i.e. the connection branch ratio and dispersion, are used to determine the circuit topology that applies to the latter method. Finally, a software about corresponding model conversion is developed. And a real distribution network is converted to RTDS simulation system by the software, which verifies the effectiveness of the software.
