Functional Testing of IEC 61850 Based Protection Relays

This paper deals with the new IEC 61850 international standard for communications in substations to implement the protection, automation and control of electric power systems. IEDs are multifunctional devices designed for substation protection, monitoring and control systems. The development and implementation of IEC 61850 based devices and substation automation systems requires a new generation of specialized test devices and methods for functional testing of different components of the system
