本文描述了一种用于测量电力系统工作频率的数字信号处理技术的设计、计算和实现。该技术在大约25ms的时间内为接近标称频率、标称频率和非标称频率提供了正确且无噪声的估计，并且它需要少量的计算。所提出的技术是使用基于DSP的电路板实现的，并且已经使用从动态频率源和电力系统获得的电压信号进行了广泛的测试。文中给出了部分试验结果。
This paper describes the design, computational aspects, and implementation of a digital signal processing technique for measuring the operating frequency of a power system. The technique provides correct and noise-free estimates for near-nominal, nominal, and off-nominal frequencies in about 25 ms, and it requires modest computations. The proposed technique is implemented using a DSP-based board and has been extensively tested using voltage signals obtained from a dynamic frequency source and from a power system. Some test results are presented in the paper.
