Electric energy qualitative data concentrator for digitalization transforming plant

An electric energy qualitative data concentrator for a digitalization transforming plant is composed of a basic function subsystem (1) and an OPC service function subsystem (2) based on IEC61850, wherein the basic function subsystem (1) is composed of a system main control module (3), a process management module (4), a protocol conversion module (5), a real-time data processing module (6), a data format conversion module (7), a historical data storage module (8), a system configuration maintenance module (9) and a data forwarding module module (10), the OPC service function subsystem (2) based on IEC61850 is composed of a data modeling module (11), a model mapping module (12) and an OPC access interface module (13). The utility model follows the IEC61850 modeling rules, converts private data into an electric energy qualitative data object model according to the IEC61850 standard and maps into uniform OPC data format, provides OPC open application program interfaces, and implements management and application of various isomerized electric energy quality monitoring data.
