摘要
提出了一种基于数字信号处理器(DSP)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,并研究了基于C500、C501的参数测量与误差校正方法,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。
A design for multi-function power network measurement instrument based on DSP is presented. The operation pattern and interface of C501, C500 and AT93CA6 chips are discussed, measurement technique and error-correcting method are studied .This instrument can make the real-time measurement of three-phase current, voltage, power factor, active power, reactive power, apparent power, frequency and energy. Its accuracy can reach to the class of 0.5.
