【摘要】 为了解决变电站自动化系统(SAS)中来自不同厂家的智能电子设备(IED)间互操作与集成的问题，国际电工委员会制定了IEC 61850变电站通信网络和系统的系列国际标准。该标准规定了基于XML的对SAS及其构成进行描述的变电站配置语言SCL。本课题以该系列标准为依据，重点研究基于SCL的IED配置工具的原理、开发以及工程实用问题。变电站内的IED采用统一的协议，通过网络进行信息交换。将一个IED集成到一个SAS中，需要用SCL对它进行描述，也就是配置，这需要一个IED配置工具。尽管标准不限制IED配置工具的实现方式，甚至允许手工配置，但基于计算机技术的IED配置工具在实际工程中是必要的。IED配置工具的主要任务是：生成各种IED的初始功能描述文件(ICD文件)，供系统配置使用；解析系统配置工具产生的系统配置文件(SCD文件)，产生IED的工程配置文件。为了满足这些功能要求，本课题构建配置信息库，结合XML解析器构造SCL解析器，使用面向对象的编程方法，开发出IED配置工具的实现软件。本课题的重点是配置信息库和SCL解析器的构建，这两大模块是IED配置工具实现的基石，也是将IEC 61850标准应用于实际的关键结合点。实现IEC 61850里规定的配置工具，无论是IED配置工具还是系统配置工具，都需要对SCL文件进行各种操作，包括修改、添加、删除等等，这就需要构建一个SCL解析器。本论文分析了配置工具中对SCL文件的解析分成两个步骤的原理，提出了编辑和解析SCL文件时，使用XML模板文件实现Schema文件对SCL文件进行约束的方法。用这种方法，构建了SCL解析器。除了SCL文件的Schema里规定的固定的基本配置信息外，IEC 61850还规定了通信结构的91个逻辑节点类和29个通用数据类。同时，还要考虑IED配置信息的模板化，这就需要建立外部模板信息库。一个通用的IED配置工具需要建立配置信息库，将以上这些配置信息放进去，以备用户调用，方便用户据此生成格式良好且有效的ICD或CID文件。一个完整的变电站配置信息库包含三部分内容，由最基础的基本配置库到扩展配置库再到外部配置库，都可以由XML文件来实现，简单方便，且易于修改与扩展，完全可以达到实际工程的功能要求。本文完成了IED配置工具的开发，分析了IED配置工具的原理及功能，给出了IED配置工具的整体模型，设计了IED配置工具的架构，最终实现了IED配置工具的程序软件。本课题对IED配置工具的研究与探索，是IEC61850标准的推广与应用工作的一部分。对IEC 61850标准的工程实用有一定积极意义。更多还原

【Abstract】 In order to solve the problems of the interoperability between Intelligent Electronic Devices (IED) from different manufacturers in substation automation system (SAS) and of system integration, International Electrotechnical Commission (IEC) constituted the IEC 61850 series of standards on communication networks and systems in substations. IEC 61850 specifies a substation configuration language called SCL which is based on XML for the description of SAS and its structure. According to the IEC 61850 series of standards, this paper will focus on studying the principle, development and applications of the IED configuration tool based on SCL.The IEDs in substation adopt an uniform protocol. They exchange information by network. When an IED is integrated into a SAS, it must be described by SCL using an IED configuration tool. Although IEC 61850 doesn’t limit the means of realization, even permits handwork configuration, but it is necessary to employ an IED configuration tool based on computer technology in practical engineering. The primary task of IED configuration tool is: building the ICD(IED Capability Description) file which can be used for system configuration; parsing the SCD(System Specification Description) file created by system configuration tool to build CID(Configured IED Description) file. In order to satisfy all requirements, in this thesis I build configuration information database and SCL parser which is based on XML parser, use object oriented program language to realize IED configuration tool.The emphases of this thesis are configuration information database and SCL parser. They are the foundation stones and the key for IEC 61850 application.It is necessary to deal with SCL file for any configuration tool including IED configuration tool and system configuration tool. So we must build a SCL parser. In this thesis I analyze how to parse a SCL file. This consists of two steps. I use XML template file to restrict SCL file.Except for the basic configuration information defined in SCL schema, there are 91 logic node class and 29 common data class information defined in IEC 61850. At the same time we must consider the configuration information model for convenience. So in this thesis I build three configuration databases: basic, outspread and external database. All of these databases base on XML.This thesis analyses the principle and function of the IEC configuration tool, provides its model and frame. Finally I fulfill the IED configuration tool.This thesis study and search after the IED configuration tool. It is one part of IEC 61850 standards’ spread and application.更多还原
