Remote calibration and online measurement method for digital energy measurement based on TDC
Due to the immature measurement specifications and non-standard measurement equipment of digital energy metering devices,the accuracy of measurement error measurement results is low.A remote calibration and online measurement method for digital energy metering based on TDC is pro-posed.According to the influencing factors of digital energy metering errors,TDC is used to measure the errors of energy metering,and remote calibration of digital energy metering is carried out based on the measurement results.The experimental results show that the digital energy measurement error measured by the design method meets the requirements of digital meter measurement accuracy,confirming the effec-tiveness of the method.
