Design and implementation of IED configurator based on SCL model

The configurations of IEDs play an important role in associating the part-6 with the part-7 of IEC 61850. Based on substation configuration description language (SCL), this paper details the design and implementation of IED configurator. Firstly, each tache in the configuration flow of IED configurator is discussed.Secondly, this paper expounds several limitations of SCL model and its modifications, and analyzes the IED configurator information model which is built on the modifications of SCL model.Finally, the software structure of IED configurator is presented.
