2017全國風能與海洋能源創意實作競賽-
季軍
這是一種以軸承驅動的點頭鴨式波浪能轉換器(Salter‘s duck) 。我們所提出的新型波浪能轉換器,主要是利用單向軸承的特性,使波浪的不規則上下運動轉換為單方向的連續轉動。直接以單向軸承的輸出軸串接至增速齒輪箱,最後傳動至永磁發電機,故可達到較高的發電效率。 本作品主要創新點為當潮汐改變的時候,發電形式也會有所改變,漲潮時利用海浪高低差的壓力帶動推拉板,退潮時利用點吸收式來發電。將多組點頭鴨結構浮筒串聯在一起,增加其受波浪衝擊面積使整個系統與波浪接觸面積增大,使波浪做出最大的功。 本展示作品為15:1縮小尺寸比例原型,經水槽測試於12.5公分之波高與1.9秒週期之波浪條件下,能量轉換效率約為7.6%,發電量為0.91w。如以1:1之實際比例製造,並經系統調校,轉換效率約可達60%。在台灣東北海域平均波高約為1.7公尺、週期7秒之條件下,單一個裝置約可產出之額定電功率約為30Kw。在100個波能轉換裝置的陣列場下,即可達3Mw之商轉輸出電量,約可提供台灣7200個家庭之民生用電。
