Development and Implementation of NPP Function Test System Based on Virtual Instrument

This paper described the virtual instrument process test platform based on Agilent VEE visual engineering environment virtual instrument graphical programming language and PC-DAQ data acquisition technology,which was connected with DCS control cabinets I/O modules and performed nuclear power plant control logic function test to realize the consistency checking between DCS configuration and system design manual.The implementation result in Ling’ao phase Ⅱ has proved that this technology could correspond to DCS control system commissioning periods and characteristics,optimize the commissioning schedule and reduce the commissioning risks.
