To facilitate the test and debugging of medium-voltage power line hardware circuit in the laboratory, this paper designs a medium-voltage power line channel noise generator based on virtual instrument technology. LabVIEW is used to generate noise data in the computer, and the noise signal is output using virtual instrument acquisition card. Software programming are mainly used in the noise generator, which solves the long-time, high-cost problems of traditional instruments. It can also output different types of noises which match medium-voltage power line channel noise characteristics, which brings convenience to the test of modulation and coding performance for the hardware circuit.
