Instantaneous Reactive Power

Based on the instantaneous reactive power theory, an improving detection method of harmonic current is put forward. In this method, the harmonic current is detected by current average. The method has the characteristics of simple structure, strong real-time and good dynamic response. In the paper, the proposed method is used to carry out simulation of MATLAB and the results show the effectiveness of the method.

Coordinate Transform

By means of building up a three-dimension coordinate system in vector space, the coordinate transform used in instantaneous reactive power theory (IRPT) proposed by H. Akagi is deduced and through spatial coordinate transform two equivalent three-dimension coordinate systems are obtained. After rigorous mathematical deduction the transformation factor for above-mentioned three-dimension coordinate systems is achieved, thus the coefficient deduction for IRPT is solved and the zero-sequence quantity expressing three-phase asymmetrical system is directly obtained. By use of the theory of rotating phasor, the basic principle of instantaneous spatial vector detection method based on IRPT is explained. The authors’ analysis is available for understanding and improvement of this harmonic current detection method.
