本文主要著重於海流發電系統的研究，在實驗設置中，一造流單元係由一具有4噸含水量的水槽所構成，藉以評估海流能對一永磁同步發電機之發電量的影響。該永磁同步發電機可由一般傳統的電機試驗方式及交、直軸參數量測方式獲得電機特性參數，並藉由該些電機特性之參數進一步評估該海流發電系統之可行性。測試海流發電系統後級轉換器之容量，利用兩套轉換器以背對背連接，再串接一負載箱作為測試，此種設計的負載箱只需要驅動器總容量的十分之一，可以大大降低測試成本。為了達到較佳發電效能，本文將利用田口方法及雙反應曲面法對海流發電系統之負載、水流流速及齒輪比等參數進行上述目的的最佳化設計。

This thesis emphasizes the evaluation of an ocean current power generation system. In experimental setup, an ocean current producing unit with an 4 ton capacity water tank is constructed to evaluate the power generated by the ocean current energy for a permanent magnetism synchronous generator (PMSG). In this thesis, the PMSG uses several machinery tests such as the locked-rotor test, the short-circuit test, QD model, and so on to obtain the electrical characteristics so as to further evaluate the power generation performance by using these characteristics. A useful test configuration for testing power capacity of the ocean current power generation system will be also proposed in this thesis. The test configuration consists of two converters and a load. The two converters are formed back-to-back connecting configuration and then serially connected with the load. The load demand is only tenth of each converter demand so as to decrease the test cost by using the test configuration. In this thesis, three factors including load, flowing velocity of ocean current, and gear ratio will be selected to evaluate the optimal design so as to provide a preferred power generation performance by using Taguchi method and response surface method respectively.
