Design and Application of Online Calibration System for Automatic Verification Pipeline of Electric Energy Data Acquisition Terminal

In order to improve the detection ability of acquisition terminal, the design scheme of automatic verification pipeline for electric energy data acquisition terminal was proposed. It designed the verification units of automatic verification pipeline and developed the calibration system for dielectric strength test unit, function and error test unit. The testing software to issue test report was developed. The analysis model for calibration data was set up. The process of uncertainty in measurement for auto-measuring result based on GUM algorithm was specified. The results show that the power parameter of automatic verification pipeline can be accurately checked by the calibration system, and consistency of multi-leaving can be ensured. The calibration system is suitable to evaluate the reliability and veracity for the set of automatic verification pipeline. So it provides technical support for speeding up the construction of the electric energy data acquisition system and strong smart grid.
