本論文旨在模擬實現並聯式主動電力濾波器(SAPF)之負載電流補償，透過同步參考座標(SRF)分析負載電流並且配合IEEE Std. 1459-2010，計算出非有效功率 ( 、 、 )之消耗，當參考補償電流超過SAPF的最大輸出時，應用選擇性補償策略來消除或比例減少非有效功率以提升SAPF的工作效率。 在電力系統設計方面，本論文採用三相四線式系統，在使用Matlab/Simulink模擬平衡與不平衡之非線性負載以及間諧波負載的架構下，量測共同耦合點(PCC)來獲取電壓與電流訊號，再透過本論文所提出的控制策略來達到補償諧波電流之作用，並且最後再分析補償後的總諧波電流失真，其數值須符合IEEE Std. 519-2014之規範以及現今台灣電力公司諧波管制標準。 在並聯主動式電力濾波器設計方面，採用八顆功率開關元件與一顆直流儲能電容作為其主要架構，利用本論文所提出的控制策略再透過磁滯電流控制進而實現諧波電流補償。 ;This thesis is aimed to achieve the simulation of control harmonic current compensation by shunt active power filter(SAPF). Analyzing harmonic signal through synchronous reference frame (SRF), and estimating the non-efficient powers with IEEE Std.1459-2010.When reference compensating current exceeds the maximum output of SAPF,a selective compensation strategy is applied to eliminate or proportionally reduce the non-efficient powers to improve the efficiency of the SAPF. In the aspect of power system design, this thesis applies three-phase four-wire system. Through Simulink to simulate nonlinear loads and inter-harmonic load in balanced and unbalanced situations, the signals of voltage and current are extracted at point of common coupling (PCC). With the control strategy proposed in this thesis, the compensation of nonlinear harmonic currents is completed. Finally, the total harmonic current distortion after compensation is analyzed to verify if it is complied with harmonic limitations presented by IEEE Std. 519-2014 and TPC harmonic regulation standards at present. In the aspect of shunt active power filter design, the eight power switches and one DC storage capacitors are used as the main structure. And hysteresis current control is used to realize the harmonic current compensation.
