本研究的目的為驗證「橫向主動繫泊海流發電系統」在長鏈狀態下的佈置角狀態、一般海況下的穩定性以及下潛躲避風浪之可行性。橫向主動繫泊海流發電系統利用潛浮於水下的水翼牽引發電機組，透過改變水翼攻角以及重心，來改變發電機在水平以及垂直方向上的位置。先前的研究透過理論分析以及初步的縮尺模型實驗對系統進行初步研究，顯示透過改變水翼的攻角，能使系統產生一定大小的佈置角，使發電機有一定大小的橫向移動，在一般的天氣狀況下長鏈系統能維持穩定，且長鏈下潛至一定深度能躲避風浪。本研究希望更進一步地透過全系統長鏈縮尺模型的定量實驗進一步驗證該系統的基本功能。首先，依照福祿數製作對應的縮尺比例模型以及流場以進行實驗。接下來針對單一發電機-水翼單位的縮尺模型進行佈置角大小分析以及穩定性觀察。然後將多個水翼-發電機單位串起來置於泳池的實驗流場中，觀察長鏈模型佈置角與單一單位及理論分析的異同及系統的穩定性。最後將縮尺模型組合成發電長鏈，並在泳池的實驗流場中製造符合縮尺規模大小的浪，以模擬不同海況，並測試其對長鏈縮尺模型的佈置角大小、穩定性以及下潛躲避風浪能力的影響。

This research studies feasibility of deployment, stability under general sea conditions and capability of storm resistance and avoidance of the Cross-stream Active Mooring (CSAM) system for marine power generation. The CSAM technique applies a set of hydro sails attached close to multiple generator turbines on a long mooring tether, all in submerged floating state, to stablize and adjust the positions of the generator turbines in the sea. Previous studies, theoretical analyses and preliminary model observations, have shown that setting different angles of attack of the hydro sails can deploy the generators at different tether deployment angles, formation of the system can be maintained and effects of storms can be avoided and resisted by increasing submerging depth. This research further verifies the basic functions of the CSAM system through quantitative scale model experiments. First, scale models of hydro sails and generator simulators were made and tested in a water tank to achieve proper Froude scaling, including the forces and thrusts resulted from the models in the flow. Next, single stage of hydro sail and generator simulator were experimented to measure the deployment angles and observe the stability in waves. Finally, multiple stages of hydro sail-generator simulators were connected into a linear array, as designed in the CSAM concept, and tested in a pool with a flow generator under different wave conditions. Experimental results show that the system can be deployed as designed. Test results also indicate that waves in regular sea conditions had negligible effect on the model system and the linear array formation was intact under waves of a 10-year recurrence typhoon.
