A generalized active power filter（GAPF） and the application problem of generalized instantaneous reactive power theory in the referential current detection of GAPF are studied. The main circuit, operating principles and referential current detection arithmetic of a GAPF are introduced and the results of a simulative experiment on the GAPF are given. Here, a three double-bridge ann PWM convertor is utilized to actualize the main circuit of the GAPF and a generalized instantaneous reactive power theory based on the αβ0 orthogonal transformation is employed to detect the referential currents of the GAPF. Through the theory analysis and computer simulation, it is shown that the proposed GAPF has the characteristics of many functions, favorable performances and so on and there are advantages of favorable real time, high precision and easy realization etc in the detection of the suggested referential currents.
