| Abstract: | In this paper, the active and reactive power are defined with the integrated vector in 3|phase circuit, and the reactive and harmonic current is obtained with the calculation of instantaneous voltage and current on the reference of voltage vector. Also the algorithm is simplified. The simulation result shows that the method leads to satisfactory detecting performance. The definition of power in this paper not only has special physical meaning but also can be applied in the detection of reactive and harmonic current. |
