智能变电站二次系统三维设计研究

Research on Three-Dimensional Design of Secondary System in Intelligent Substation

针对变电站二次系统的特点,结合以往设计经验,从二次系统建模原则、建模要求与可视化展示、设备“四统一”接口的要求、二次回路数字化展示等方面研究三维设计对变电站工程建设的影响;提出二次设备与一次设备模块化设计、与土建专业间接口标准化和统一化的方案;建立智能二次设备柜内光缆回路、电缆回路模型,建立电缆回路与原理图,支持同名虚端子自动连接,为智能变电站的建设、运行提供借鉴与参考。

In view of the characteristics of the secondary system of the substation,combined with previous design experience,this paper studies the influence of three-dimensional design on the construction of of substation projects from the aspects of secondary system modeling principle,modeling requirements and visualization display,requirements for"four unified"interface of the equipment,and digital display of secondary circuit.The modular design of secondary equipment and primary equipment and the scheme for standardization and unification of interface with civil engineering specialty are proposed.The models of optical cable circuit and cable circuit in intelligent secondary equipment cabinet and the cable circuit and principle diagram are established,and the automatic connection of the virtual terminal with the same name is supported,which can provide reference for the construction and operation of future intelligent substations.
