摘要
智能电能表的时钟是控制费率切换的根本依据,时钟的准确与否直接关系到能否准确计量峰、尖、平、谷等各种时段的电量。本文阐述了96表位智能电能表检定装置检定时钟误差的计量方案,研究分析了检定过程中产生时钟偏差的因素,提出了检定优化方案,通过试验数据的对比,表明优化后的方案极大地提高了时钟检定的准确性。
Smart meter clock is the fundamental of controlling the rate switch. Clock which is accurate or not is direct- ly related to smart meters＇ ability to measure the peak, sharp, flat, valley and other time of electricity charge. Ac- cording to practical work, this paper describes the program of 96 meter verification devices to test the clock errors, an- alyzes the factors of clock skew during the verification process, and proposes the optimization methods. By comparing the experimental data, it shows that the optimized program greatly improves the accuracy of clock verification.
