摘要: | 本論文提出適用於主動式電力調節器之動態優化電流調變方法。當主動式電力調節器之輸出實功率驟變時,可透過動態優化電流調變決定適當之輸入電流以穩定直流匯流排電壓,減少直流匯流排電壓之波動,進而降低直流匯流排電容值。另一方面,由於不同程度之實功率變載對於直流匯流排電壓之影響不一,因此,論文中也將針對不同之直流匯流排電壓調控速度進行探討,並列出動態優化電流調變之數學推導式。此外,本論文亦開發主動式電力調節器之通訊功能,研製一組控制器區域網路(Controller Area Network; CAN)通訊界面,讓使用者不僅能透過人機介面監控系統之運轉參數,也可下達實虛功命令以執行微電網間之功率調配。最後以5kVA之硬體實測波形來驗證本論文所提出之動態優化電流調變效果以及通訊功能。 A dynamic optimal ac line current modulation (DOCM) method for the active power conditioner (APC) is proposed in this thesis. The proposed DOCM method is able to determine the appropriate input current to stabilize the dc-bus voltage as soon as an abrupt power change of the APC occured. By adopting the proposed method, the dc-bus voltage fluctuation can be minimized while providing the feasibility of the dc-bus capacitance reduction. On the other hand, in order to regulate the voltage variation under different power changing scenarios, the regulating slope of the dc-bus voltage under different operating conditions are discussed. Mathematical equations for the proposed DOCM method are derived thoroughly in this paper. Besides, a Controller Area Network (CAN) communication interface is developed for the system monitoring and the power flow control between two micro-grids. Finally, experimental measurements obtained from a 5kVA prototype circuit are presented to verify the performances of the proposed DOCM method. |
