【摘要】：随着IEC61850标准在智能变电站内的深入应用,能够承载海量数据的数字通讯网络替代了传统的电缆接线方式。设备之间的信息传输方式由常规变电站内电缆传输的电信号转变为光纤传输的数字信号,原来“看得见、摸得着”的采样值输入和跳闸输出的端子连接,变成了基于网络传输的SV/GOOSE(sample value/Generic Object Oriented Substation Events)数字信号。智能变电站的设备之间回路不再是以电缆传输单一信号构成的纯电路结构,而是以光纤数字通信为基础的网络化结构,每一根光纤中同时传输多路SV/GOOSE信号,无法再从外部直接的物理连线去分析整个回路,取而代之的则是设备之间的虚拟回路。传统的通过万用表、继电保护测试仪等工具直接调试和检测设备层的手段已经不能满足智能变电站的调试和检测需要。本文通过分析智能变电站设备的调试与检测工作流程,以IEC61850标准的一致性为基础,开发了一套以PC机为硬件平台,跨平台的、具有图形界面的智能变电站设备层可视化系统。该系统通过仿真智能变电站内多个智能设备的功能,可视化展示设备之间相互订阅的GOOS信号传输,SV信号的传输,并且验证SV/GOOSE信号连接传递的正确性,实现四方公司在智能变电站调试与检测过程中的“准确化、可视化、快速化”,可以帮助设计和工程人员清晰查看的全站设备的互联关系,提升全站设备的调试和检测工作效率,能方便分析和诊断工程实施及运行维护中出现的复杂问题,提高了工作效率,大大的节省了成本。
[Abstract]:With the application of IEC61850 standard in intelligent substation, digital communication network, which can carry mass data, has replaced the traditional cable connection mode. The mode of information transmission between devices is changed from electrical signal transmitted by cable in conventional substation to digital signal transmitted by optical fiber. The original "visible, tangible" sampling value input and tripping output terminal are connected. It turns into a SV/GOOSE(sample value/Generic Object Oriented Substation Events) digital signal based on network transmission. The circuit between devices in intelligent substation is no longer a pure circuit structure composed of a single signal transmitted by cable, but a networked structure based on optical fiber digital communication, in which multiple SV/GOOSE signals are transmitted simultaneously in each optical fiber. It is no longer possible to analyze the entire loop from a direct external physical connection, instead of a virtual loop between devices. Traditional tools, such as multimeter and relay protection tester, can not meet the needs of intelligent substation debugging and testing. Based on the analysis of the debugging and testing work flow of intelligent substation equipment and based on the consistency of IEC61850 standard, this paper develops a visual system of intelligent substation equipment layer based on PC as hardware platform and cross-platform with graphical interface. By simulating the functions of several intelligent devices in intelligent substation, the system visualizes the transmission of SV signals by GOOS signals subscribed to each other between the devices, and verifies the correctness of SV/GOOSE signal connection transmission. To realize the "accurate, visual and fast" in the debugging and testing process of intelligent substation by Sifang Company, which can help design and engineer to see clearly the interconnection relationship of the whole station equipment. It is easy to analyze and diagnose the complex problems in the implementation and maintenance of the project, improve the working efficiency and save the cost greatly by improving the debugging and testing efficiency of the whole station equipment.
