摘　　要：提出一种中频电量参数测量的新方法。通过交流同步采样技术,处理器对交流信号直接采样,计算得到电压、电流等参数。将电压、电流方波送入处理器,通过输入捕捉(Input Capture,ICP)功能获取交流信号的频率及相位差,进而利用两瓦计法求得三相功率。A new method for measuring electric parameters is presented. AC voltage and current signals are sampled directly by AC synchronous sampling. After transformed into square waves, the voltage and current signals are sent into processor and the frequency and phase difference are measured by the input capture function of the processor. The three-phase power is calculated with the two-wattmeter method.
