A New Referenced Signal Detection Method Adaptive to Multi-Objective Control of Active Power Filter

Abstract:

That the control objectives of active power filter are diversified is an import measure to improve application efficiency of active power filter. This paper puts forward a new referenced signal detection method based on generalized orthogonal transformation, and expatiates of the basic theory of generalized orthogonal transformation and detection principles and their realization methods of all kinds of referenced signals. Finally, simulative results are given. Theory analysis and simulative results show validity of the proposed detection method.
