| Abstract: | A fast arithmetic to synchronized measurement of power system voltage and current phasors is proposed in this paper.Based on the known signal model and using the sampling data of the signal on certain time points,the proposed arithmetic fast gives the signal parameters.The attenuating direct component is considered in the arithmetic.With the arithmetic the signal parameters can be calculated even in the fault or oscillation situation of the power system.The proposed arithmetic can be used in PMUs and protec... |
