摘要
本文提出了一种新型的智能模块用于水轮机调速器的机组频率、电网频率及其相位差的测量，与传统的设计相比，硬件电路大大简化，具有更高的测量精度，可靠性也得到了提高．并介绍了测量原理。
An intelligent frequency-and phase-measuring module of a water turbine governor with the newly microcontroller 80C51FA is proposed in this paper.It is much less in hardware and PCB size, more precise and more reliable in comparison with that by conventional design.Its measurement principle,hardware and software design are described.
