Design Of Substation Configuration Tool Based On IEC 61850 Standards

The IEC61850 standard, designed by IEC TC57 is the newest international standard on substation automation. Named Communication Networks and System in Substations, It stands as the trend of the SAS. And it is the newest development of substation automation system. The worldwide electrical corporations are paying great attentions to the standard, which has become the direction of the design and construction of new substation.The main aim of IEC61850 is to product a standard and opening Substation Automation System, which will finally accomplish real interoperability of SAS, so as to reduce maintenance,improve communication and so on.Using the SCL(Substation Configuration Language) to describing the functions and devices of substation is one of the core technologies of the IEC 61850 System, and it is very important to the safety and stable operation of the Substation Automation System. As the standard states, the substation configuration is defined as two related process, those are IED configuration and system configuration. And, in principle, we can develop two different kinds of configurating tools to deal with the IED configuration and system configuration respectively, and also, this two kinds of configuration tools can be integrated as one general configuration implement. So far, although a small number of manufacturers have published their available products based on IEC 61850, such as ASE's Visual SCL and Kalki's SCLManager, which can accomplish the major work of the substation configuration, but, the project practice of the SCL management tool is still needing more research and development devotion, especially at domestic, the requirement of the configuration tool is imminency.This thesis firstly introduces the establishment, the background, the function and the organization of IEC61850. Further the main items of the standard are chiefly discussed, and then, the newly editing situation of IEC61850 series and many other relational standards are introduced. This paper focuses on the theory foundation of The Substation configuration, involving the Substation Configuration Language, the communication models of each device and function in the SAS, then, using an example, the paper explores the method of the substation configuration. The rest of the article is engaging in the development of the configuration tool, which can easily create the documents describing the function and structures of SAS using the SCL. After completely analyzing the required capability of the configuration management, the article designs a general SCL managing tool conform to the IEC6180 standards at the Microsoft Windows environment. And at last, working with an IED instance, the SCL managing tool perfectly accomplishes the SCL configuration mission.
