本文旨在研製小型風力發電用之儲能系統。本系統可將三相永磁式同步發電機所產生之變動電壓及頻率的交流電壓轉換為固定電壓及頻率之單相電源，並藉蓄電池儲能系統負責能量儲存與功率補償，以彌補風能不穩定之特性。本文之系統採用低成本，且容易實現之三相全橋式二極體整流器作為發電機側電路之主架構，並加入三相Y接與各相獨立接法切換技術提高風能使用率，低速時採三相Y接線的三臂型二極體整流器，高速時採各相獨立繞組之六臂型二極體整流器，以維持穩定直流匯流排電壓。市電側採用單相直流-交流功率轉換器，將發電機及蓄電池之功率轉換為電能，提供負載使用或與市電併聯。最後，能源管理部分，使用降壓／昇壓型直流-直流功率轉換器作為蓄電池儲能與釋能之控制，完成系統平衡。
　　本文以高性能的數位信號處理器TMS320F28335為整體系統之控制核心，其控制策略皆由軟體程式完成，不但減少硬體電路元件及成本，並增加系統運作可靠度。本文完成在三臂及六臂型二極體整流於獨立運轉模式下，對單相負載輸出交流60Hz、110V之定電壓，輸出功率為300W；在市電併聯模式下系統供給333W，其效率為90%。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 analysis and design of battery energy storage systems for small wind power generation. The system can transfer the three-phase permanent-magnet synchronous generator from varying-voltage and varying-frequency to 60 Hz single-phase source, and the battery is used for energy storage and power compensation to compensate the natural irregularity of the wind power. The system uses three-phase full-bridge rectifier, which is low-cost and realized easily, to become the generator side power converter, to generate electric power over a wide range of wind condition along with wye-connected winding or independent winding. When the wind speed is low, the ac-dc power converter uses three-leg rectifier structure to raise the dc-link voltage. Whereas, when the wind speed is high, the ac-dc power converter uses six-leg rectifier structure converter to keep dc-bus voltage lying within the constant range. The proposed single-phase inverter can not only provide the power of the generator and the battery but also operate in either stand-alone or grid-connected fashion. Finally, a buck-boost dc-dc power converter is designed to charge and discharge batteries in order to regulate the power flow between renewable energy and system loads.
　　A high-performance digital signal processor TMS320F28335 is used to implement the control function to control the power converters. An experimental system is built. The system can provide single-phase ac 110V to single-phase load under stand-alone operation. The output of the effective power is 300W. Under grid-connected mode, the power converter supplies 330W with the corresponding efficiency of 90% using the topologies of three-leg and six-leg rectifier structures. Finally, experimental results are given to justify the analysis.
