臺灣博碩士論文加值系統

本論文探討太陽能與風力發電系統之整合研究，其中風力用發電機分別使用永磁發電機與同步發電機兩種不同發電機型式。為了改善兩種不同發電機在隨機風速下所產生之不同電壓與頻率特性，以及在不同負載下之負載效應，本文提出利用整流模組及蓄電池來同時完成風力及太陽能的儲能並改善風力發電機之負載效應。此蓄電池電能再經由換流模組來同時得到固定頻率與電壓之輸出，除可供應獨立負載外也可與市電系統並聯。
本論文在三相平衡系統下採用交直軸等效電路模型，分別建立永磁發電機、同步發電機、太陽電池、整流器、蓄電池與換流器之模型，分別推導其數學模式來完成整體動態方程式，並利用特徵值法來求出系統之動態穩定度。硬體架構則採用實驗室之500 W永磁發電機組、300 W同步發電機，經整流模組後與1.5 kW太陽電池模組及24 V蓄電池模組合併，再經由容量4.5 kW換流模組供應負載。由模擬與實測結果互相比較，以驗證本論文所提系統模型之可用性及正確性。

This thesis presents the results of a study on integration of a permanent magnet generator (PMG)/a synchronous generator (SG) and a PV System. A PMG and a SG are respectively utilized as a wind generator. To improve variable frequency, variable voltage, and loading effects of both generators under random wind speeds, a rectifier module and a battery system are employed to combine both PV and wind systems. The stored energy in the battery system is converted into constant voltage and constant frequency by means of an inverter module to supply isolated loads or connect to a utility grid.
A d-q axis equivalent-circuit machine model is employed to establish the PMG, SG, rectifier, inverter, PV, and battery models in order to derive the complete dynamic equations of the studied system under three-phase balanced loading conditions. The derived system model is also employed to obtain system eigenvalues to determine dynamic stability. Experimental results obtained from a laboratory 500 W PMG, a 300 W SG, a 1.5 kW PV system, a 24 V battery system, and a 4.5 kW inverter module are compared with the simulated results to validate feasibility of the proposed models.
