摘要
对DSP技术在电度表中的应用进行了研究,对电度表系统的误差进行了分析,提出了采用软件方法来补偿误差的措施,使电度表的精度达到了设计要求,又避免了利用硬件进行误差补偿所带来的弊端,不用在线路中调整电压、电流采样值,有利于生产。
In this paper, the application of DSP technology in electric power measurement meter has been studied, meanwhile analysed the error of the electronic energy meter, put forward the measure to compensate error with software method. It not only changes the precision degree of electric power measurement meter, but also avoids the disadvantage from error compensate with hardware method, it is unnecessary to adjust the sample value of voltage and electric current in circuitry.
