In response to the problem of insufficient automatic measurement accuracy of digital high-voltage meters,this article introduces a new multi-level AC/DC digital high-voltage meter automatic measurement calibration method for distribution systems.This method establishes a multi-layer AC/DC power grid architecture for a new distribution system,analyzes the operating principle of digital high-voltage meters in the multi-layer AC/DC power grid of the new distribution system,and obtains the voltage error value of the new distribution system's multi-layer AC/DC power grid through the calculation method of automatic measurement error of digit-al high-voltage meters based on the average value principle.After designing an automatic measurement calibration device for high-voltage meters,Based on the voltage error values of the multi-layer AC/DC power grid in the new distribution system,the calibration coefficient for automatic measurement of digital high-voltage meters is calculated.This calibration coefficient is used to achieve auto-matic measurement and calibration of digital high-voltage meters.At the same time,after analyzing the uncertainty of digital high-voltage meters,further optimization and optimization of automatic measurement and calibration of digital high-voltage meters are car-ried out based on this uncertainty,making the automatic measurement results of digital high-voltage meters more accurate.The exper-iment shows that this method is more accurate in calculating the voltage error value of the multi-layer AC/DC power grid in the new distribution system,and can effectively calibrate the automatic measurement of digital high-voltage meters.The application effect is significant.
