| Abstract: | According to the principle of four-quadrant power measurement,analysis was made to the four-quadrant distribution of impedance angle,voltage phasor and power state.A new kind of method to discriminate three-phase AC phase sequence was set forth.The principle of three-phase AC phase sequence discrimination was discussed in detail.AC sampling technology was used to realize phase sequence discrimination.Simulation verification in Matlab shows that this strong practicable method is simple in discriminative way,... |
