摘要
工频频率变化会影响电量计算的准确性 ,甚至会影响到电力自动化装置的工作性能。文章介绍了基于单片机的实现采样频率同步跟踪的三种方法。给出了具体的软件算法和硬件电路 。
The frequency variation of electrical power system would have effect the veracity of electric parameter evaluation,and possibility effect characteristic of automatic equipment. Three means to realize synchronous tracing sampling frequency based on microcontroller are discussed. In this paper special hardware circuit and software algorithm are introduced,which have some reference to the manufacture equipment of real-time measuring.
