一种新的数字电能表校准方法研究
Study of a New Algorithm of Digital Wattmeter Calibration
摘要
Abstract
According to the characteristics of the digital meter which is widely used in the power supply system; an algorithms of calibration based on the digital all-pass phase-shifting filter is proposed to solve the problems of the traditional method; involving the high measuring complexity; bad real-time performance and inapplicability in embedded measuring device. The algorithm of digital meter calibration studied in the paper mainly refers to two aspects-trie standard digital power source calibration and the calibration of the whole calibration device. Considering the measurement uncertainty; the standard uncertainty of input amount and the uncertainty of synthetic standard are assessed to verify the effectiveness of the proposed algorithm.关键词
