The effect of phase oscillation on BSEM algorithm model

In 2011, the American Institute of Electrical and Electronics Engineers (IEEE) published the standard of synchronized phasor measurement in power system. In the first part, which is named IEEE Std C37.118.1™-2011, put forward the algorithm reference model BSEM-(Basic Synchrophasor Estimation Model) and each performance index of various testing environments. This paper analyzed the requirements of measurement accuracy and response time of the test case like low frequency oscillation, out-of-band frequency proposed in the criterion, put forward the effect of phase oscillation to the measurement algorithm and the restriction on parameters of digital low-pass filter design when the send rate is 25Hz. According to the corresponding measurement error and computational overhead from the simulation results, it provides guidance for practical research of PMU-(Phasor Measurement Unit).
