本論文旨在從事風力永磁同步發電機為基礎雙極性直流微電網之開發及操控。首先建立一風力永磁同步發電機，並加以適當控制，於變動之速度和負載下獲得良好之發電特性。比較評定發電機後接之三相單開關、三相雙開關和三相三開關維也納開關式整流器。在合適強健電壓和電流控制下，建立調控良好之微電網直流鏈電壓。此外亦提出均壓控制方案，減少雙極性直流鏈之電壓不平衡。對於具維也納開關式整流器之風力發電機，從事換相時刻設定之探究及實測評定，以有效利用磁阻功率成份。
接著，構建蓄電池儲能系統，提供微電網之能源緩衝，在變動風速下之供電品質得以提升。蓄電池經由雙向直流-直流升/降壓轉換器連接到微電網直流鏈。經由適當之電路及控制器設計，獲得良好之充放電操控特性。

This thesis focuses on the development and operation control of a wind interior permanent-magnetic synchronous generator (IPMSG) based bipolar DC microgrid. First, the wind IPMSG is established and properly controlled to possess satisfactory generating characteristics under varied driven speed and load. Then the boost switch-mode rectifier (SMR) based bipolar DC bus is established. The generator followed by three-phase single-switch (3P1SW) boost SMR, three-phase two-switch (3P2SW) three-level boost SMR and three-phase three-switch (3P3SW) Vienna SMR are comparatively evaluated. With the proposed robust voltage and current controls, well-regulated microgrid DC-bus voltage is established. Moreover, the voltage balancing control is proposed to minimize the bipolar DC-bus voltage imbalance. For the wind IPMSG with Vienna SMR, the commu- tation angle setting to effectively use the reluctance power component is conducted and verified experimentally.
Next, a battery energy storage system (BESS) is constructed for supplying energy buffer to the microgrid. The power supplying quality is improved under fluctuated wind speed. The battery bank is connected to the microgrid DC-bus through a bidirectional three-level DC/DC boost/buck converter. With proper designs of schematic and controller, satisfactory charging and discharging characteristics are achieved.
Finally, a bidirectional single-phase three-wire (1P3W) inverter is designed and implemented. Thanks to the bipolar DC-bus arrangement, only two inverter legs are needed. The proportional-resonant (PR) feedback controller is designed to yield 60Hz 220V/110V AC voltages with good waveform quality to power the unknown and nonlinear loads. Furthermore, the bidirectional grid-connected operation is also conductible. Successful microgrid-to-home (M2H), microgrid-to-grid (M2G) and grid-to-microgrid (G2M) operations are demonstrated by measured results.
