Three-phase unbalance factor monitor platform design of electronic power based on LabVIEW

This paper designs a suit of three-phase unbalance factor monitor platform software by using virtual instrument (VI) technology of corresponding software LabVIEW8.5. In order to prove system platform design´s accuracy, we carry out simulation signal producer designing, which simulating and proving system accuracy. Three-phase unbalance factor monitor platform using VI technology can largely reduce hardware design with software design simple and renew convenience. This paper mainly introduces platform hardware and software design method, and process of simulation signal production-simulation ways. This platform that paper introducing can also be applied to other electronic power quality monitor, and has better transplanted character.
