The SCU 810 module is a complex communication device intended for the interconnection of any intelligent electronic device (IED) of Iskra NEO 3000 (NEO 2000) Substation Control and Protection System and of any third-party vendors. IED is considered as numerical protection relay, bay computer, intelligent RTU, energy counter and alike, that is used within the substation.
The SCU 810 device covers communication functions needed within substation and functions of data handling, world time synchronization and substation automation. It can serve also as interconnection gateway between hierarchically different control system levels from substation to utility dispatching centers, where data from geographically spread substations are grouped into a single database that forms an integrated supervision system of a wider
area power system. SCU 810 is a multi-protocol device that enables simultaneous communication with different IEDs connected on separate communication ports using any listed protocols. Hardware extension of communication ports is possible by using ECU 032 extension unit that provides up to 64 ports. For communication with devices over IEC 61850 there can be use optical network with star or ring configuration. SCU 810 also supports number of inevitable automatic functions when it is used as a master automation controller in Distribution Automation System.
