基于SED文件的智能变电站改扩建二次系统配置文件自动重构技术研究

针对改扩建工程实施过程中原SCD文件更新时存在版本控制、设计交互困难的问题,结合IEC61850Ed2国际标准,首次提出了基于SED文件的改扩建二次系统配置文件自动重构技术。采用基于SED文件的局部重构技术在改扩建工程中将SCD文件在设计配置流程上充分解耦,保证了改扩建部分的相对独立性。通过SED文件在改扩建工程中的规则定义机制,保证了已投运设备不会在改扩建设计阶段误修改,同时提升了在运设备的安全性。

Study on automatic reconfiguration technology of secondary system configuration file based on SED file for smart substation reconstruction and expansion

In the process of implementation of the reconstruction and expansion project, there are problems of vision control and design interaction when the original SCD file is updated. Combined with the international standard of IEC61850 Ed2, the automatic reconfiguration technology of the secondary system configuration files for the reconstruction and expansion project based on the SED file is proposed for the first time. In the reconstruction and expansion project, the local reconfiguration technology based on SED file is used to fully decouple the SCD file from the design and configuration process, which ensures the relative independence of the reconstruction and expansion. Through the rule definition mechanism of the SED file in the reconstruction and expansion project, it is guaranteed that the operation equipments will not be modified in the design stage of the reconstruction and expansion and the safety of the operation equipments is improved.
