The IEC 61850-9-2 standard describes the abstract model of the digital voltage and current sampled values (SV) used by 61850 enabled intelligent electronic devices (IED). IEC 61850-9-2 is very flexible and can be implemented in a multitude of configurations and does not specify a fixed configuration. This brought about the commonly used 9-2LE configuration, which is an implementation agreement of 9-2 adopted by a majority of IED manufacturers. China however did not adopt this configuration and used a configuration more akin to the IEC 61850-9-1 configuration. This paper describes the development of an IEC 61850-9-2 configurable interface firmware and a software model for use on a Real Time Digital Simulator (RTDS®).
