技術說明

一種可應用於風力發電之激磁式同步發電機最大功率追蹤控制方法，本發明於風力發電系統中利用激磁式同步發電機，結合主要風力來源與一個電動機可穩速及相位控制的動力源，使傳遞一個穩速及可控相位的動力源給激磁式同步發電機，並偵測市電頻率、相位，配合輸出功率回授控制，進而利用控制激磁式同步發電機的激磁電流來達到最大功率輸出。本發明所提出應用於風力發電之激磁式同步發電機最大功率追蹤控制方法，可應用於例如風力、水力、火力、洋流與潮汐發電等各種動力發電系統場合，以達到與市電並聯和最大功率輸出的目標。 A control method of an excitation synchronous generator for maximum power tracking in wind turbine application is disclosed. In the present invention, after combining the wind power source and the synchronous motor, the excitation synchronous generator is driven by a stable power source input with speed and phase control. The excitation synchronous generator output power can incorporate with the utility bus by detecting the frequency, phase of the utility bus. Furthermore, the excitation synchronous generator output a maximum power by output power feedback control and excitation current control structure. The proposed control method of excitation synchronous generator for maximum power tracking in wind turbine application can be utilized in every power generation system field such as wind power, waterpower, firepower, and tidal power. The power generation system applying the proposed method can achieve the maximum power output and electricity incorporation objectives.
