A synchronized phasor measurement unit is designed for ship power system. The synchronized clock unit, data collect unit and data processing unit are presented in detail. An approach based on the Nuttall window double-spectrum-line interpolation FFT is used for electrical harmonic analysis, extended C37.118 for ship’s power system synchronized phasor measurement. Tested by a standard signal source, the results show that the amplitude measurement error is less than 0.2% and phasor measurement is less than 0.2°,meet the requirements of the power system stablization monitor and control.
