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。
FBD
为了更好地进行谐波和无功功率的补偿与控制,叶FBD(Fryze一Buchholz一DPenbrock)法的定
义进行了完善,并给出了补偿电流检测的直接法和间接法,在三相电力系统中对FBD间接法进行
了推广研究,利用参考电压进行投影变换,不仅可以检测出功率电流和零功率电流,还可以检测出
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.)
