| dc.description.abstract | 本文針對黑潮流速特性提出一低轉速直驅式的永磁同步發電機之模擬，並根據發電機特性透過Matlab/simulink進行併網模擬，以確保發電機併入市電後可以有效地提供電源。首先，根據黑潮流速為1 m/s至2 m/s之間以及葉片特性在流速1.3 m/s至1.5 m/s之間可以轉換超過10 kW功率，並以此作為發電機規格之參考，設定出額定轉速為30 rpm且額定功率為10 kW的低轉速直驅式永磁同步發電機規格。文中透過有限元素分析軟體Ansys Maxwell進行發電機內部磁場強度的模擬，由於發電機在運作時，最容易產生磁飽和的區域為定子靴部，因此在模擬上也針對靴部進行最佳化，以找出最適合的靴部參數。再來將發電機進行空載及負載模擬，以確認發電機在不同操作模式下，皆符合一開始的需求。在併網方面，本文透過Matlab/Simulink對併網控制進行模擬，首先將前面設計的發電機參數輸入至併網系統中，並利用軟體中的工具箱Simscape Power Systems內的元件建立背對背轉換器與電網模型，並將背對背轉換器分為發電機端的控制與電網端的控制，在發電機端的控制主要以實現最大功率轉換為原則，使發電機可以操作在最大功率係數的轉速上，而在電網端的控制則以直流端的穩壓與虛功控制為主，使背對背轉換器中的直流端電壓不會受發電機的轉速所影響，並確認電能經過轉換後可以有效的將功率輸出。 | zh_TW |
| dc.description.abstract | In this paper, we proposed a 10 kW low speed direct-driven permanent magnet synchronous generator simulation and grid-connected simulation. According to Kuroshio current speed and the blade design, we decide to set the generator specification to 10 kW when the generator operates at 30 rpm. The generator is simulated by using Ansys Maxwell. We simulate the magnetic field in the generator to avoid the electrical steel of the stator and the rotor operate at saturation mode. We also simulate the different speed and load of the generator to realize the performance of it. After we finish the simulation, we use the parameter of the simulation result to build the grid-connected system in Matlab/Simulink. The grid-connected simulation includes machine side control and grid side control. The objective of machine side control is to achieve maximum power point tracking, and grid side control is to achieve DC-link voltage control. The results help us to ensure that the generator can inject the power to the grid effectively. | en |
