Research On IED Configurator Based On IEC61850

IEC61850 is the international standard about the substation automation system communication published by the International Electrotechnical Commission, which is used to unify the communication network system to improve the interoperability,openness and extendibility. The purpose of the standard is to realize interoperability for substation IEDs from different manufactures. IEC61850 is the solution for the substation seamless communication. Especially, by introducing the SCL (Substation Configuration Language), IEC61850 makes the self-description of the IED (Intelligent Electronic Device) becomes possible.The description of substation configuration is very important to the safety and stable operation of Substation Automation System (SAS). IED configurator and system configurator are used in the process of configuration. So far, although a small number of manufacturers have produced available products based on IEC61850, the IED Configurator demands more research and development in projects. IED configurator is developed in this paper.Firstly, IEC61850 is analyzed in this thesis, including: introduction of standards, key content of standards and its realization process. Secondly, the IEC61850-7 Modeling Principles, the main idea of SCL and the leveling data model described by SCL are introduced. This paper analyses the principle and function of the IED configurator, provides its model and frame. According to the data model described in SCL and by using VC++ as the programming language, IED Configurator Software is developed. The configurator provides a visual editor to easily configure and browse SCL document. Finally, by using a practical project in a traction substation as example, and on the basis of the main wiring diagram of the actual equipment, ICD documents are generated.This thesis realizes the design and implementation of IED configurator, which are parts of IEC61850 standard's application. The realization has a positive meaning for the IED configurator based on IEC61850 standard in engineering.
