摘　　要：本文介绍了一种采样速率与采样精度的最优匹配方法,该方法可用于基于交流采样技术的电力网参数监测系统的设计。利用MSP430F2012单片机搭建了交流采样实验平台,实验结果表明采样速率与采样精度符合一定的内在关系时,采样系统将达到最佳性能。This paper introduced a method about the matching of the sample rate with the resolution. This method can be used to design the monitoring system of the power network based on the alternating sampling technology. This experiment was finished by the MSP430F2012 single chip computer. The result showed that the sampling system will get the best performance when they accord with some inherent relation.
