智能变电站虚端子辅助自动设计系统

Aided automatic design system of virtual terminals in intelligent substation

针对当前智能变电站的虚端子表设计过程繁琐、智能性不高问题,为提高虚端子设计的自动化,设计了智能变电站虚端子辅助自动设计软件系统。利用以往SCD构建了历史数据库,以历史关联设备对及其虚连接为参考,研究了基于IED信息和共同关键词的目标设备对的准确匹配与查找方法,给出目标设备的目标虚连接的模糊匹配方法。研究了在历史数据库中查找目标关联对、与当前待设计IED的虚端子模糊匹配、自动生成参考的虚连接等技术,提供了界面上手工拖放修改虚连接、复制设备与间隔的虚连接等功能。通过实际变电站的设计应用,验证了本系统的有效性,提高了虚端子设计的智能性和工作效率。

For the problem of virtual terminal table design in the intelligent substation such as complicated process and low intelligence,the aided automatic design system of virtual terminal is designed to improve intelligence of design for virtual terminal.This paper uses previous SCD files to build history database,takes historical associate equipment and its virtual links as references,studies accurate matching and searching method based on IED information and common keywords,and gives the fuzzy matching method for target virtual links of target equipment.The technologies including searching associated virtual links of IED from the history database,the fuzzy matching with the virtual terminals of current designing IED,automatic generation of virtual links are achieved.The functions,such as the modifying virtual links with dragging and dropping manually on the interface,duplicating virtual links among similar bays and devices,etc.are provided.The effectiveness of the automatic design method is verified by the practical intelligent substation design.The system can improve the intelligence and work efficiency of virtual terminal design.
