摘　　要：由于数字化电能计量装置的测量规范不成熟、测量设备无标准,导致计量误差测量结果的精度较低,文章提出基于TDC的数字化电能计量远程校准及在线测量方法。根据数字化电能计量误差的影响因素,采用TDC测量电能计量的误差,并针对测量结果对数字化电能计量进行远程校准。实验结果表明,设计方法测量的数字化电能计量误差符合数字表计量精度的要求,证实了该方法的有效性。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 proposed.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 effectiveness of the method.
