Research on Fault Diagnosis of Gas Pressure Regulator Based on Digital Twin

The gas pressure regulator plays an extremely important role in the gas transmission and distribution pipeline network. In order to respond to the failure of the pressure regulator in a timely and accurate manner, the digital twin technology is used to carry out the numerical simulation of the three-dimensional model of the gas pressure regulator. In this paper, grid generation and numerical simulation under normal conditions for a certain type of voltage regulator are carried out. The simulated data are consistent with the field experimental results. The research and design of the voltage regulator model under the fault condition of the sawtooth grooves, and the development of the experimental plan, the field test platform also meets the experimental needs, it is feasible to analyze the failure of the specific location of the voltage regulator through the digital twin method.
