Application Research Of Fault Oscilloscope System In Digital Substation

By analyzing conventional micro fault oscilloscope's constitution principle, technical characteristic, disposition principle and important index and so on in main electrical network.The problem that can't be solved while digital oscilloscope applies to transformer has been summed up in this paper. Combined with functional requirements of digital oscilloscope for digitized transformer, analyzed on structures and overall plan of digital secondary system. Carried on detailed analysis contrast to sampling value installed technology as well as GOOSE installed technical program. Based on hardware, software platform and analysis software system's construction method of GOOSE fault oscilloscope, Realize digital oscilloscope record which is the same moment and device such as electric measurement value and switch value of GOOSE tripping protective movement circuit breaker deciliter etc. This design method obtains the successful application in actual project.
