Comply With The Iec61850 Standard Ied Configuration Tool Of Realization

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.
