主 题:Phasor measurement unit(PMU) field test signal identification oscillation
摘 要:Synchrophasor measurement units(PMUs)provide synchronized measurement data for wide-area *** improve the effectiveness of synchrophasor-based applications,field PMUs must be tested to ensure their performance and data *** the companion paper(Part I),we proposed a field PMU test and calibration framework consisting of a PMU calibrator and analysis *** I presents the development and test of the PMU *** paper focuses on the analysis center and field test ***,the critical component of the analysis center is the signal identification module,for which the step and oscillation signal identification methods are ***,the performance evaluation criteria of PMU in these two cases are different from *** methods include a step signal detection method based on singular value decomposition(SVD),which has the capability of weak step detection to account for energy leakage of the signal during the step process,and an oscillation signal identification method based on SVD and fast Fourier transform,which can accurately extract oscillation components that benefit from the adaptive threshold setting ***,the analysis center software is implemented based on identification *** integrating the PMU calibrator in Part I with the analysis center in Part II,we can examine in depth the field PMU test applications in three test scenarios,including standard,playback,and field signal *** demonstrate the effectiveness and applicability of the proposed field PMU test methods from both Parts I and II.
