本論文係分析以波浪驅動之波浪能轉換系統，搭配雙側管型線性永磁發電機獨立供電及併聯市電系統運轉之特性。在本論文中，將以單部「阿基米德波浪搖擺」驅動線性永磁發電機，並經由電力電子轉換器併聯電網與連接獨立負載之架構做為研究模型。由於波浪週期隨時間與地點而改變，在分析時將採用頻率掃描與動態響應兩種方法來分析系統特性。本論文在三相平衡系統下採用交直軸等效電路模型，分別建立波浪、「阿基米德波浪搖擺」、線性永磁發電機、整流-換流模組等模型，推導其數學模型來完成整體動態方程式。本論文亦利用有限元素法進行線性永磁機之磁場分析與模擬，了解其運轉特性並求取線性永磁發電機等效模型中所需的重要電氣參數。在穩態方面，則針對不同波浪高度與獨立負載條件，進行系統的波浪頻率掃描與負載掃描，詳細探討浮蓋移動速度、線性發電機輸出功率、系統根軌跡變化等。在動態研究方面，則完成波浪波高與波浪週期的變化、併接點端三相短路故障與無限匯流排電壓驟降之模擬。本論文最後設計一組相位補償控制器來改善所研究波浪發電系統直流鏈電壓的穩定性。

This thesis analyzes the operating characteristics of a wave energy conversion system (WECS) that contains an Archimedes Wave Swing (AWS) system driving a doubled-sided tubular linear permanent-magnet generator (LPMG) fed to a power grid and independent loads through power-electronics converters (PECs). Since the wave period varied with time and location, both frequency scanning and dynamic-response analysis are adopted in this thesis. A q-d axis equivalent-circuit model is employed to establish the wave, AWS, LPMG, and PECs to derive the complete dynamic equations of the studied system under three-phase balanced loading condition. The finite element analysis (FEA) is also utilized to analyze the magnetic field distribution of the LPMG in order to obtain its important electrical parameters. The velocity of the translator, the output power of the LPMG, and the root loci of the studied system under different wave periods are discussed in detail. Dynamic simulations of the studied system subject to various values of wave period and wave height, voltage drop at the power grid, and a three-phase short-circuit fault at the power grid are also carried out.
