Abstract
IEC 61850 has become the preferred standard for substation automation for many utilities around the world. However, its provisions to automate control systems in a substation remain a lesser-discussed topic of the IEC 61850 standard series. Testing and validation of control systems in an electrical substation such as high voltage switchgear controls can be a challenging task due to the unavailability of an accurate replica test system. However, such control systems can be conveniently tested in a virtual environment by modelling them inside a real-time simulator. This paper presents the use of a simulation model developed with standard IEC 61850 logical node classes for representation, testing and validation of switchgear and their associated controls in a digital substation automation system.
