摘要

目前的雙饋型感應發電機大多是採用轉子電壓命令為主之控制，本文是以轉子電流命令直接輸入進而控制雙饋型感應發電機的實功和虛功輸出。首先針對雙饋型感應發電機(Doubly-Fed Induction Generator, DFIGs)風力機組，以向量控制原理發展其實功和虛功以及電容電壓控制架構。為了能有效的控制雙饋型感應發電機，本論文將a-b-c三軸分量之雙饋型感應發電機電流控制之模型轉換為d-q兩軸分量，再分別利用PI線性控制器以及返步式非線性控制理論(Backstepping theory)設計控制器以實現發電機實功和虛功的控制。
本論文分別以PSCAD/EMTDC和Matlab/Simulink兩套模擬軟體對PI控制器以及返步式非線性控制器分析與驗證。同時亦對於模擬軟體PSCAD/EMTDC和Matlab/Simulink進行比較。經模擬後結果顯示，本文所設計的控制器確實能有效控制發電機輸出實功和虛功。

Currently, most of Doubly-Fed Induction Generators(DFIGs) were controlled by the rotor voltage commands. This thesis directly inputs rotor current commands to control the real and imaginery powers of DFIGs. First, the vector control principle is used to develop the real power、imaginery power and capacitor voltage controls. In order to effectively control DFIGs, the model of DFIGs are transformed from the a-b-c frame to the d-q axis frame. Then both the PI linear control and Backstepping nonlinear control theories are adopted to realize the control of the real and imaginery powers.
The PSCAD/EMTDC and Matlab/Simulink are used to simulate and verified the proposed PI control and Backstepping nonlinear control respectively. Meanwhile, the PSCAD/EMTDC and Matlab/Simulink are compared in the simulation chapter. The results confirm the performances of the proposed real power、imaginery power and capacitor voltage controllers
