本論文研製一套可供應獨立負載之風力發電用能量轉換系統,為了改善獨立運轉風力發電系統輸出電壓及頻率受隨機風速變化以及連接不同負載的特性影響,本文設計及研製一套由交流-直流-交流電力電子轉換器所組成的能量轉換系統,配合脈波寬度調變原理結合數位信號處理器作整合控制,並完成感應發電機及同步發電機為電能輸入之風力發電機控制,觀察並比較能量轉換器在不同發電機組下之工作特性。
本文之硬體架構採用一部2.2 kW感應發電機組、一部300 W同步發電機組、德州儀器公司生產的TMS320F240數位信號處理器來完成實體製作,並採用三相a-b-c系統模型,結合三相感應發電機、三相同步發電機、三相整流器、直流-直流昇壓器與直流-交流換流器,推導完整的數學模型以完成系統動態方程式。由模擬與實測結果互相比較,可驗證本論文所提風力發電用能量轉換系統之可行性。
The aim of this thesis is to research and study a wind power energy conversion system feeding an isolated load. Both output voltage and frequency of an autonomous wind generator would be inherently affected by random wind speed and the connected loads, and this thesis proposes an AC-DC-AC power converter to minimize the problems using the integration of both DSP and PWM control. Both induction generator and synchronous generator are employed as two wind power generators in order to observe and compare the characteristics and performance of the proposed energy conversion system.
A 2.2 kW induction generator set, a 300 W synchronous generator set, and a TMS320F240 DSP produced by Texas Instruments are practically utilized in this thesis. Three-phase induction generator, three-phase synchronous generator, three-phase rectifier, three-phase DC-AC inverter, and DC-DC booster are integrated to form complete system dynamic equations for detailed simulation. It can be concluded from the simulated and experimental results that the practical application of the proposed wind power energy conversion system is feasible.
