Operating algorithm and hardware implementation of sinusoidal signal parameter measurer in generator excitation circuits

A certain algorithm and hardware implementation used to measure current and voltage parameters in electric generator during excitation are considered. As is generally known, measurement time for these parameters plays a crucial role. Until recently, the performance of such devices has been limited by frequency of the generated voltage (50 Hz). The paper presents an algorithm and hardware implementation of the parameter measuring-predicting device which possesses higher performance.
