摘 要：By particular theoretical analyzing on detection error of the traditional current loop proportion-integral(PI) controller,this paper points out the limitations of detection harmonic current at load side and proposes a current feedforward compensation *** can track harmonic instructions with zero static error and good compensation ***,it overcomes the deficiencies of traditional load side detection harmonic current PI controller,with the traditional controller s *** if the load harmonic current is higher than the capacity of active power filter,it can basically maintain zero static error output and has certain theoretical significance and engineering *** analysis and simulation prove the new control strategy s correctness and effectiveness.
