摘要: 为了提高电参数测量的便利性和准确性,提出了一种基于数字信号处理器的多功能电网参数测量仪设计方案.对C500、C501、AT93C46的工作方式和接口等进行了讨论,采用了基于C500的误差校正法以提高测量准确度,实现了对交流电网中三相电流、电压、功率因数、有功功率、无功功率、视在功率、频率、有功及无功电能的实时测量,测量准确度达到0.5级.Abstract: For improving the convenience and accuracy of measurement, design method of a DSP-based measuring instrument for multi-function power network is proposed. The paper discusses operation pattern and interface of C501、C500 and AT93C46 chip. In order to improve measure accuracy, error rectify method based on C500 is adopted. This instrument can measure three-phase current, voltage, power factor, active power, reactive power, apparent power, frequency and energy etc.. The measure accuracy reaches 0.5-level.
