1、摘 要【通顺的原文和英文如下两页：】作为智能电网的组成环节，智能变电站在状态监测、故障检测与控制方面 起到重要的作用。As an part of the smart grid, smart substation has played an important role in condition monitoring, fault detection and control. 在以 IEC61850 为基础的智能变电站中，网络传输过程层、间隔层及其之 间联系的二次回路信号代替了传统的电缆信号； In a IEC61850-based intelligent substation, the tra
2、ditional wired signal was replaced by signals of the secondary circuit, which come from the process level of network transmission and bay level; 为了有区别于传统变电站的屏端子接线，智能变电站给出了虚端子的设计概念。In order to distinguish with the connection of panel terminal,intelligent substation gives the design concept of virtual
3、 terminals. 目前，各设计院采用虚端子表文件 （Excel）定义和设计虚端子信息， Currently, the design institute use document of virtual terminal(a kind of excel) to define and design the information of virtual terminal;但是它们的格式各异，很大 程度上影响了设计人员设计意图的准确表达及测试人员对其理解与测试工作。 But those documents have different formats,which influenced the de
4、sign intents accurately expressing of the designer and also testers understanding or testing in a large extent. 现阶段及相当长的一段时间，虚端子设计既有相似性又有差异性，较难实 现所有虚端子的完全统一。The design of different virtual terminal have similarity and diversity simultaneously,which is difficult to achieve the complete reunification
5、of all virtual terminals at present even for a long period of time. 因此需要设计一种合理的虚端子规范提供给设计院和厂家参考，并开发虚 端子表规范化转换软件，方便设计院及联调工作人员查看不同格式的虚端子表。Therefor ,we need to design a reasonable and normative virtual terminal for design institute and company,develop a software for transforming virtual terminal to a s
6、tandardized one,which will give design institute and related personnel a great convenience to read the virtual terminal. 本文首先简单阐述了智能变电站的现状、发展和虚端子表文件的研究现状、 意义； Firstly，this thesis briefly described the status、development of the intelligent substation and the research status,objective of the virtual t
7、erminal documents, 接着把 IEC61850 标准及与虚端子有关的概念进行了简要的介绍。 then briefly introduced the related concept of IEC61850 standard and virtual terminal. 其次,本文对已有的几种格式的虚端子表文件（高山虚端子表、扎窝虚端子 表等）的结构进行了详细的分析。 Secondly, the structure of sever kinds of existing virtual terminal such as ( virtual terminal excel in Gao S
8、han,virtual terminal excel in Za Wo, etc.) have been detailed analysis in this thesis. 通过总结其优缺点，得出虚端子表规范的思路，并给出了虚端子表规范建 议的具体内容及具体的规范表格示例。 By summing up the advantages and disadvantages, the specifications ideas on virtual terminal excel are drawn , its details and specific examples of standard virtu
9、al terminal are given . 本文然后根据继电保护“六统一”标准中对虚端子表的相关规定，给出了线 路保护、母线保护、220KV 电压等级主变保护等典型保护装置虚端子表的设计 方案。 Thirdly ,the design of virtual terminal excel of typical protective devices such as the line protection,the bus protection and the main transformer protection in 220KV，on the basis of relay protection
10、 standard , is presented in this thesis . 本文最终结合规范虚端子表的格式，开发了一个虚端子表规范化转换软件。Finally,a transform software was finished by combining the form of standard virtual terminal. 该软件能够依照对应的转换关系把不同格式的虚端子表转换成规范格式的 虚端子表，并能通过读写 XML 文件灵活的实现新增对应转换关系功能。 The software can transform the different virtual terminals exce

13、，智能变电站在状态监测、故障检测与控制方面起到重要的作用。在以 IEC61850为基础的智能变电站中，网络传输过程层、间隔层及其之间联系的二次回路信号代替了传统的电缆信号；为了有区别于传统变电站的屏端子接线，智能变电站给出了虚端子的设计概念。目前，各设计院采用虚端子表文件（Excel）定义和设计虚端子信息，但是它们的格式各异，很大程度上影响了设计人员设计意图的准确表达及测试人员对其理解与测试工作。现阶段及相当长的一段时间，虚端子设计既有相似性又有差异性，较难实现所有虚端子的完全统一。因此需要设计一种合理的虚端子规范提供给设计院和厂家参考，并开发虚端子表规范化转换软件，方便设计院及联调工作人员查
14、看不同格式的虚端子表。 首先，本文重点阐述了智能变电站的现状、发展和虚端子表文件的研究现 状、意义；接着把 IEC61850 标准及与虚端子有关的概念进行了简要的介绍。其次,本文对已有的几种格式的虚端子表文件（高山虚端子表、扎窝虚端子 表等）的结构进行了详细的分析。通过总结其优缺点，得出虚端子表规范的思 路，并给出了虚端子表规范建议的具体内容及具体的规范表格示例。然后，本文根据继电保护“六统一”标准中对虚端子表的相关规定，给出了 线路保护、母线保护、220KV 电压等级主变保护等典型保护装置虚端子表的设 计方案。最后,本文结合规范虚端子表的格式，开发了一个虚端子表规范化转换软件。 该软件能够依
15、照对应的转换关系把不同格式的虚端子表转换成规范格式的虚端 子表，并能通过读写 XML 文件灵活的实现新增对应转换关系功能。因此，该 软件既可以根据已有的对应转换关系也可通过新增对应转换关系，把所有不同 格式的虚端子表转换成规范的虚端子表。关键字：智能变电站；IEC61850；虚端子表；GOOSE；SV；转换软件AbstractAs an part of the smart grid, smart substation has played an important role in condition monitoring, fault detection and control.In a IE
