飛輪儲能系統之充電與無位置感測

飛輪儲能主要是將電能轉換為動能，讓飛輪不斷地在真空中旋轉，以達到儲存能量的目的。本論文主旨在開發飛輪儲能系統，架構主要包含：直流無刷馬達、三相三線式全橋變頻器、輔助電源與微控制器周邊電路等。本論文主要有線上參數估測、驅動方法與電流控制法。線上參數估測採用最小平方遞迴法，再使用LCR-Meter量測馬達線圈，以驗證估測值。驅動方法主要以適用於零轉速啟動與低轉速的高頻訊號注入。再搭配以空間向量脈波寬度調變(Space Vector Pulse Width Modulation, SVPWM)為基礎的分切合整之電流控制法，並透過微控制器來實現前述的控制方法。

In the flywheel energy storage, the electrical energy is converted into the kinetic energy by making the flywheel spin nonstop in the vacuum. This thesis develops the flywheel energy storage system. The hardware consists of a permanent magnetic synchronous motor, a three-phase three-wire inverter, a flyback and the peripheral circuits of the micro-controller. The online parameter identification, the sensorless control and the current control are introduced in this thesis. The motor parameters are measured by the LCR meter to verify the online parameter identification. High frequency injection is adopted to estimate the rotor speed and the rotor position by this thesis. It is suitable for the motor at black start and low speed. The SVPWM is proposed in this thesis for division-summation current control. All of the controls are accomplished via the micro-controller.
