智能变电站二次系统物理回路建模方法及设计实现

摘要

智能变电站二次系统逻辑回路遵循IEC 61850建模，而物理回路的设计仍采用图纸表达，不利于智能变电站信息化技术的发展。借鉴逻辑回路的建模思路，提出二次系统物理回路的建模方法。设计了基于虚实解耦理念的物理回路模型配置流程；给出了物理回路模型的语法语义；实现了基于物理回路模型的完整工程应用解决方案，包括物理回路配置工具、物理回路可视化工具。关键的是采用虚实对应技术，实现了物理回路和逻辑回路的关联。填补了二次光缆和网络结构的模型配置空白，便于设计工具和厂站级系统导入和导出物理回路配置，扩展了物理回路模型的应用空间。%The logical circuits of smart substation secondary system follow IEC 61850 for modeling, while the design of physical circuits is still expressed with blueprint, which is unfavorable to the development of smart substation information technology. By referring to the modeling idea of logic circuits, a modeling method of the secondary system physical circuits is proposed. A model configuration process of physical circuits based on the concept of logical-physical decoupling is designed. The grammar and semantics of the physical circuit model are given. A complete engineering application solution based on the physical circuit model is realized, including the physical circuits configuration tool and physical circuits visualization tool. The key technology adopts the logical-physical corresponding in order to realize the association between physical circuits and logical circuits. The model configuration blank of secondary optical fiber and network structure is filled. It is convenient to import and export physical circuits configuration for the design tool and substation automation system. The application space of physical circuits model is extended.
