多芯模组化的负荷分析电能表设计与研制

针对居民用户对精准精益用能服务需求不断增长的现状,为提升智能电能表精细化用电数据分析水平,基于IR 46国际建议的理念,设计研制了一款基于多芯模组化方案支持远程升级的负荷分析智能电能表.该电能表内置计量芯片、功能芯片及负荷分析专用芯片,各芯片模块相互独立,通过负荷数据采集、特征量提取、负荷辨识、记录上传等过程,实现三芯管理模式下的用户家庭电器类型、启停时间、消耗电量智能辨识分析.同时提出了依托用电信息采集系统的远程升级方案,保证电能表负荷分析算法、特征库可在线更新.

Design and development of electricity meter for load identification based on multicore modularity

Currently, demand of precise and lean energy consumption service for residents is growing constantly. Aiming at this situation, according to the principles of International Recommendation 46, an electricity meter for load identification based on multicore modularity is designed to improve the level of detailed electric data analysis. With metering module, general function module and load analysis module embedded separately, intelligent identification for type, turn-on/off time and electricity consumption of household appliances is realized in triple cores management mode by load data sampling, load sign extraction, load matching and results upload.so a remote update scheme rely on electric information acquisition system is proposed to ensure online update for load identification algorithm and load sign database.
