DETECTION DEVICE AND DETECTION METHOD FOR SECONDARY VIRTUAL LOOP OF SMART SUBSTATION

摘要

Disclosed in the present invention are detection device and a detection method for a secondary virtual loop of a smart substation. The detection device includes: an input end of a configuration file reading module (10) connects with an output end of a background (13) of the smart substation; an input end of a configuration file parsing module (11) connects with an output end of the configuration file reading module (10); a digital signal generator (12) connects with a smart equipment acquisition card (20) and a smart operation box (30) respectively; the output end of the smart equipment acquisition card (20) connects with a merging unit (14) of the smart substation and an industrial switch (15) in turn; an output end of the smart operation box (30) connects with the industrial switch (15); an output end of the industrial switch (15) connects with an input end of an photoelectric converter (16); an output end of the photoelectric converter (16) connects with an input end of a virtual loop detection module (17). The technical solution can comprehensive detect connection performance of a secondary loop of the whole smart substation, guarantee accuracy of actions of a secondary equipment of the smart substation, provide technical base for accepting, transforming and improving an automatic system of the smart substation and a secondary equipment, and benefit safety production and stable operation of a power grid.
