The phenomenon of unbalanced electricity in different time is worse and worse. In order to adjust electric power burthen with reason and save energy, we put forward the design of a novel multirate threephase watthour meter. The design principle of a novel multirate threephase watthour meter based on AT89LV5 is proposed in this paper. The designs of hardware and software flow, as well as the analysis of experiment data are presented in detail. By trial manufacturing in Zibo Billion Electron Limited Company, it demonstrates that this multirate threephase watthour meter has the characteristics which are walking precision, accurate measurement, automatic meter reading, flexible time period setting and low cost. Therefore, this novel multirate watthour meter has a broad application prospect. Keywordsmultirate, threephase watthour meter,AT89LV52 I. INTRODUCTION The development and application of puter technology push the construction of intellectualized section exteriorly. Because the phenomena of bigger demand of electric power and unbalanced electricity in different time is worse and worse, electric power pany has encouraged people to use multirate watthour meter [1] in order to adjust electric power burthen with reason and save energy. The traditional multirate watthour meter 本科學(xué)生畢業(yè)設(shè)計(jì) （論文）附件 附件 C：譯文 C10 always adopts mechanical tinplate to measure. There are some shortings that the measurement precision falls with machine abrasion, single time period setting and strong manpower [2]. In this paper, we propose a novel mul
