Analyses and comparisons of SCL files in substation configurator

In order to improve the efficiency of electric system and reduce the works of maintenance, scholars from different countries have studied the substation automation. Nowadays, IEC61850 standard is the main rule to regulate the communication between substations. The paper studies the way to use substation configuration description language to describe models of IEC61850, compares the differences of SCL (substation configuration description language) file and discusses the rules of substation configuration description language (SCL) files in actual substation project.
