  1. Secondly, to achieve the independent regulation of active and reactive power output from the generator side which is designed for the purpose of tracing the maximum wind - energy capturing. the paper has analyzed the mathematic model of the ac excited doubly - fed machine and the stator field orientation control strategy of the motor as vscf wind power generator. thirdly, it has put forward and designed the dual pwm converter with the capacity of energy flowing bidirectional aimed at the demand of rotor energy bidirectional flow. the author constructed reliable and integrated experimental system and did a series of experimental study including no - load, cutting - in network and power generation at, below and above the synchronous speed

    論文首先分析了風機運行特性及其最佳風能利用原理,通過模擬及實驗驗證了採用直流電機的輸出特性模擬風機的最大輸出功率曲線的可行性,並給出了模擬系統的硬體結構;然後為了實現交流勵發電機有功、功功率獨立調節機理,分析了交流勵雙饋發電機的數學模型和在追蹤最大風能捕獲變速恆頻風發電時必需的矢量控制策略;針對雙饋發電機轉子能量雙流動的要求,提出並設了具有能量雙流動能的雙pwm交流勵用變頻器;最後為實現從理論到實踐的全面研究,研製出了一套小功率完整的雙pwm變頻器交流勵的雙饋風發電機實驗系統,進行了空載、並網、同步速及上、下的發電運行等一系列的運行實驗;所完成的模擬和實驗研究均驗證了理論、模型和控制策略的正確性、可行性。
