Abstract:It is found that the accuracy of the phasor algorithm is affected by synchronization error. Frequency measurement is determined as an important part for phase compensation algorithm. Distributed cycle compensation algorithm is proposed for phase error of power system acquisition channels. Phase absolute error is measured and compensated using gain impedance measurement method by frequency response analyzer(FRA) taking the measurement error into account. The compensated phase could be obtained combining with phase relative error compensation algorithm based on recursive frequency measurement. Experimental results show that the compensated phase error can meet the requirements of phase accuracy for most application of power system, and the effective data can be provided for the stability of power systems and failure analysis.
