Detection for reactive current based on the theory of instantanous reactive power
Journal Title: Science Paper Online - Year 2008, Vol 3, Issue 8
Abstract
On the basis of the improved synchronous coordinate transformation, a test method of reactive current combined with the theory of generalized instantaneous reactive power is presented in order to realize the real-time and accurate detection for the harmonic and reactive current. Results of simulation show that the presented method can test the general instantaneous reactive compensative current, i.e. the sum of harmonic component, asymmetrical component and reactive current component more accurately. It can be used under the circumstance of three-phase symmetrical voltage without distortion and that of three-phase asymmetrical voltage with distortion. Results of theoretical deduction and simulating experiments verify the correctness and effectiveness of the method.
