永磁同步風機模擬器供電之直流發電系統

Abstract

本論文實現以永磁同步風機模擬器供電之直流發電系統。在永磁同步風機控制方面，適當改定轉矩電流與轉速之關係，達到風能發電特性曲線。在直流發電系統中，僅使用一組雙開關雙向直流/直流轉換器搭配蓄電池，利用最大功率追蹤演算法調節等效輸出負載，以控制風能輸出在最大功率之下，並維持風機輸出功率與負載功率平衡。本文以DSP (Digital Signal Processor)實現演算法及控制器。

In this thesis, the DC generating system fed by simulator of wind turbine permanent magnet synchronous machine (PMSM) is studied. Only one stage bidirectional DC/DC converter is used. The curve of torque current V.S. rotor speed is given to achieve the characteristic curve of wind turbine. In the DC generating system, for maintaining the output power of wind turbine within the maximum power point and balancing the power of wind turbine and load, the proposed MPPT Algorithm is used. All the algorithms and controllers are implemented in Digital Signal Processor (DSP).
