The authors introduce two digital signal processing algorithms for frequency deviation measurement in power systems. The algorithms are derived using a novel signal processing scheme based on quadratic forms of signal samples. These algorithms provide high measurement accuracy over a wide range of frequency changes. One is designed for measurements of small deviations of the nominal frequency, whereas the other measures off-nominal frequency deviations. Performance of the algorithms is evaluated using computer simulation tests. >
