Tutorial 1: IEC 61850-Principles, Applications and Benefits


Tutorial 1: Alexander Apostolov, Principal Engineer for OMICRON electronics, USA

Title; IEC 61850-Principles, Applications and Benefits


The tutorial will cover briefly the history and fundamental principles of IEC 61850, its applications and benefits. The consepts of abstract models and services and their mapping to specific protocols will be presented. The principles of GOOSE and sampled values, their communication mechanisms, applications and benefits, including their use for synchrophasor communications, will be described. The IEC 61850 configuration language ideas, different files and their application in the engineering of protection and control systems will be discussed. Requirements, methods and tools for the testing of IEC 61850 based systems will be covered at the end.
