used 12 MAX 197 pairs external signal sampling. Using Fourier
采用12位MAX 197对外部信号采样。采用全周波傅立叶积分算法,对采样信号进行处理,对电力系统的电压有效值、功率等特征量进行实时在线监测;采用全数字测量法测量相位差;并采用自适应技术调整采样间隔,消除非同步采样对计算造成的误差,利用PIC18F458捕获功能实时监测电力系统频率波动,修订采样间隔。分析了各量的测量误差,均达到标准。并提供友好的人机交互界面。-used 12 MAX 197 pairs external signal sampling. Using Fourier-Cycle Integration Algorithm for the sampling signal processing, power systems to the RMS voltage, power characteristics of the volume in real-time on-line monitoring; All digital measuring method phase difference; Adaptive technology and the sampling interval, the elimination of non-synchronous sampling of the calculation error using PIC18F458 capture real-time monitoring of power system frequency fluctuations amended sampling interval. The analysis of the measurement error are up to standard. And to provide a friendly man-machine interface.
