基波有功电流、基波无功电流、谐波电流以及任意次谐波电流等，大大拓展了FBD法的应用范围和领域。MATI一AB仿真和实验结果表明了所定义和推广的电流检测方法的正确性和有效性。
(In order to improve the performance of active power filter(APF) harmonic current detection method, a harmonic current detection based on FBD(Fryze-Buchholz-Dpenbrock) algorithm was proposed. Reference voltage was generated by phase locked loop(PLL), and load current was projected to reference voltage, and then the active power fundamental current, reactive power fundamental current, harmonic current, fundamental negative sequence current, any harmonic current and so on can be detected accurately by using low-pass filter(LPF), and in the case of distorted voltage, the method was also applicable. The simulation results verify the fast dynamic speed, high detection accuracy, simple implement and good project value of the proposed algorithm. MATLAB simulation results confirm the feasibility and validity of the method.)
