本文旨在研製以數位信號處理器為基礎之小型風力發電系統。本系統可將風力發電機所產生之變動電壓及頻率的交流電源轉換為固定電壓及頻率之三相電源。風力發電機方面，本文採用雙三相永磁式同步發電機配合全橋式二極體整流器之並聯電路結構，不僅可降低整流後直流電壓之漣波成分，亦可縮小體積及成本。在直流-直流功率轉換方面，本文提出能量平衡管理系統，採用昇/降壓式直流截波器控制蓄電池之儲、釋能，以維持供電的可靠性。另於直流-交流功率轉換方面，本文採用三相三階層直流-交流功率轉換器，將直流鏈電壓轉換為交流電源，其優點為有效減少輸出電壓之諧波含量，且可獨立供電及與市電併聯，達到分散式供電系統之功能。
本文利用套裝軟體Matlab/Simulink進行系統模擬，作為系統控制器設計之依據。採用高性能及低成本的數位信號處理器TMS320F2812為整體系統之控制核心，其控制策略皆由軟體程式完成，不但可減少硬體電路成本，並可增加系統運作之可靠度。本系統已完成520W的發電系統雛形。系統在獨立運轉下，其額定輸出線電壓有效值為220V，頻率為60Hz。在併聯運轉下，可提供實功率及虛功率至電力網路。此外，整體系統之運轉效率為81%，且三相三階層直流-交流功率轉換器輸出線電壓之總諧波失真率為2.57%。實驗結果驗證本文之理論分析及控制法則的可行性。

This thesis presents the development of DSP-based small wind power conversion systems. In this system, paralleled full-bridge rectifiers and dc-to-ac power converters are proposed to convert ac power generated by wind with varying-voltage and varying-frequency to three-phase electrical power with constant-voltage and constant-frequency. In wind generator, the proposed three-phase double-winding permanent-magnet synchronous generator with paralleled full-bridge rectifiers can not only reduce the voltage ripple at the output of rectifiers, but also decrease the size and cost of the system. In dc-to-dc power converter, the buck/boost dc chopper is designed to charge and discharge batteries. It can accomplish the management of energy balance control and enhance the reliability of the system. In dc-to-ac power conversion, a three-phase, three-level power converter is proposed to reduce the output voltage harmonics. The system realized can be operated either in a stand-alone or grid-connected operation fashion.
In this thesis, digitized mathematical model and controller design are built and simulated by Matlab/Simulink. Then, a high-performance, low-cost digital signal processor, TMS320F2812, is used to implement the system for reducing the circuit components and cost. A prototype of 520W wind power conversion system is developed. The system can feed proper power to the grid in grid-connected operation, while for stand-alone operation, the rated line-voltage is 220V and the frequency is 60Hz. Besides, the experimental results show that the efficiency of the whole system reaches 81% and voltage harmonic distortion of three-phase, three-level power inverter output is 2.57%. Finally, simulation and experimental results are given to justify the analysis.
