Monitoring of power grid main parameters based on virtual instrument

The monitoring system of power grid main parameters was designed based on the virtual instrument technology. The general study of the power quality problems, power grid main parameters and the overview of the virtual instrument were introduced in this paper. The system structure and the software design of the power grid parameters monitoring system were introduced in detail. The hardware design was introduced simply. Finally, summary of the design system was given, and the further research work and prospect was put forward.
