本論文旨在開發一以感應馬達渦輪模擬器驅動之風力永磁同步發電機。最大風能擷取及雙向聯網操作可藉由適當的背對背轉換器電路及控制器設計實現之。
首先介紹所建之間接式磁場導向感應馬達驅動系統及風渦輪模擬器。透過適當設定間接式磁場導向控制中之額定磁通電流命令與轉差角速度命令,使感應馬達獲得良好之驅控性能,所提測試方式可更準確地估得馬達之關鍵參數。所開發之感應馬達驅動系統在速度模式下,可做為傳統發電機之渦輪機使用。另外,在轉矩模式下,可實現忠實之風渦輪模擬器。可產出於不同風速下所設計之轉矩-速度及功率-速度曲線,驅動機械耦接之風力發電機。
接著,建立由感應馬達渦輪模擬器驅動之永磁同步發電機。在傳統發電機下以電壓模式操作,經由切換式整流器建立調節性良好之直流鏈電壓。而做為風渦輪模擬器驅動之風力發電機,採用擾動觀察法達成最大功率追蹤,以擷取風速變化下之最大風能。
最後,以所設計之一雙變頻器實現雙向聯網操作。在電網至微電網模式下,微電網可從電網獲取能量,而具良好之入電電力品質。反之,可進行微電網至電網之操作,藉由所提控制,可將預設之實功及虛功功率回送至電網。
This thesis develops a permanent-magnet synchronous generator (PMSG) driven by the induction motor (IM) based turbine emulator. Through the proper schematic and controller designs for the equipped back-to-back converter, the maximum wind power extraction and the bidirectional grid-connected operations are achieved.
The indirect field-oriented (IFO) induction motor drive and the wind turbine emulator (WTE) are first presented. Satisfactory IM driving performance is obtained via properly setting the rated flux current command and slip angular speed command in the IFO mechanism. The employed motor parameters are more accurately estimated by the proposed testing approach. The developed IM drive can be controlled to act as a traditional turbine in speed mode for conventional generators. On the other hand, by operating under torque mode, a faithful wind turbine emulator is established. The designed torque-speed and power-speed curves under varied wind speed are generated to drive the mechanically coupled wind generator.
Next, the PMSG with followed switch-mode rectifier (SMR) driven by the IM based turbine emulator is established. It is operated under voltage mode for conventional generator. Well-regulated DC-bus voltage is established. As to the wind generator driven by the WTE, the maximum power point tracking (MPPT) via perturb and observe method is made to extract the maximum wind power under varied wind speed.
Finally, for conducting the grid-connected operation, a bidirectional grid-connected inverter is designed and implemented. In grid-to-microgrid (G2M) operation mode, the microgrid can be powered from the grid with good line drawn power quality. Conversely, the microgrid-to-grid (M2G) operation can also be conductible. The preset real and reactive powers can be sent back to the grid.
