Description
本發明大體上係關於再生能量發電系統,且(在一特定然而非限制具體實施例中)係關於使用感應型發電機產生從快速移動水流導出之電力的潛水或水媒系統。
隨著化石燃料之成本上升及全球經濟及產業中漸增之能量需求,業者已不斷地尋求開發能源之不同及有效率方法。特別受關注的係例如所謂再生替代能源,例如電池及太陽能裝置、風力發電機、及從隔離氫導出電力之系統。
然而,此類能源尚未能在商業規模上傳送電力至分布廣的區域。此外,一些已提出的技術(如涉及海水精煉之氫發電系統),其在轉換過程中實際上消耗比在該系統末端處所輸出更多之電力。他者(例如從甲烷導出氫)會產生與其意欲取代之習知以石油為基技術相等或更大量的化石燃料排放,且又他者(如電池、太陽能及風力為基之系統)需要持續地曝露在顯著之陽光或風力下以致其商業效能固有地受限制。
一種經提出之替代能量系統涉及從快速移動水流(例如具有2m/s或更多之尖峰流速之水流)導出之水力的利用。
然而,實際上現存水下發電裝置具有經驗證之不適當處,即使其安裝在流速持續極快速之地點。此係(至少部分)由於缺乏有效率方法來用於產生電力且用於將從水下發電系統獲得之電力相容地轉移至一轉接地或水媒中繼站。
現存螺旋槳設計及水媒發電機構已被證明為不適當,其無法相對於最高速度流提供適當能量產生或足夠穩定性。
另一重要問題係關聯自水流獲得能量而不損及周遭水中生命(例如礁、海生植物、魚群等等)之環境課題。
因此,需要一種重要及目前未符合需求之水流發電系統,其克服此項技術中現存的問題且其依安全、可靠及對環境良好之方式將明顯數量之電力轉移至中繼站。
本發明提供一種水流發電系統,其包括藉由一本體結構結合之複數漂浮管;藉由一本體結構結合之複數壓載室;複數感應型發電單元,其係佈置於聯結該等漂浮室、壓載室及本體結構之一或多數的外罩內;及複數螺旋槳,其係佈置以與該等感應型發電機單元之各者機械連通。
以下說明包括一些範例性系統設計及使用本發明標的之具體優點的方法。然而,熟習此項技術人士應理解所揭示之具體實施例將會容許在無一些本文列舉之特定細節下實現。在其他情況下,為人熟知之海下及發電設備、協定、結構及技術未詳盡描述或顯示以避免混淆本發明。
第1圖描述一水流發電系統101之第一實例性具體實施例。在其最簡化形式中,該系統包含一漂浮管102、一壓載管103及一配有一螺旋槳105之感應型發電單元104。
雖然第1圖看似僅描述一單一漂浮管102、一壓載單元103及發電機組件104,其事實上係一更大系統的側視圖,且包含多數管及發電機組件的商用具體實施例係已涵蓋及描述於下。然而,熟習此項技術人士將會易於瞭解一具有特定元件之限制系統的描述係說明性,且將不限制在此揭示之標的之範疇。
本系統之新穎性在於感應型發電單元104,其對於操作提供簡單性及可靠性,且產生可輸出而無須轉換成一交流電(AC)至經聯結中繼站(未顯示)之電力。該系統因此係能依商用可變規模產生AC電力,其可易於售予鄰近電網或藉由其使用。
大體上,感應發電機機械及電氣方面係比其他型之同步發電機或直流電(DC)發電機更簡單。其亦傾向於更強健及耐久,且通常無須電刷或整流器。
例如,當一電氣三相異步(如籠式繞組)感應機器操作得比其同步速率更慢時將作為一馬達;然而,當相同裝置操作得比其同步速率更快時將作為一感應發電機。
簡言之,當一內部軸旋轉得比同步頻率更快時感應發電機可用以產生交流電力。在本發明中,軸旋轉係藉由佈置於一相對較快移動水流中之相關螺旋槳105達到。
從該系統導出之電力在許多情況下將係意欲輔助一鄰近電網系統,且因此該網之操作頻率將支配用於發電系統的操作頻率。例如,許多大型電網系統目前使用約50或60赫茲之操作頻率。
然而,感應發電機並非自激發,因此其需要一外部電源供應(如可易於從使用通過水或在一相關海底下之臍式延伸的相鄰網獲得)或藉由減少電壓起動器之「軟啟動」以提供一初始旋轉磁通量。減少電壓起動器可對於該系統提供重要優點,例如快速決定適當操作頻率,且在由於某種原因(例如由於颶風造成之損壞)下附屬電網未啟動之情況下允許一無動力再起動。
對於大型水媒發電系統之重要考慮係一平衡良好漂浮平衡之建立,其允許持續動態位置而不論周圍流速。即使假設周圍流速保持在一可接受操作速度之預定範圍內,系統平衡仍可能受到特別強大颶風或類似者之危及,但系統在典型波力之線相當下方(即約100至150英呎深)之配置將會大幅減少此等干擾。重力、浮力、阻力及保持力之各種偏移力亦將貢獻於一持續水流發電系統之整體穩定性。
第1圖中說明之漂浮管102包含一圓柱形本體部分,其係佈置於一與裝載以上所述感應發電機之至少一末端蓋單元104機械連通。該等發電機及相關末端蓋外罩含有一用於螺旋槳105之驅動軸及(在一些具體實施例中)的相關行星齒輪。
在一些具體實施例中,漂浮管102包含一立方形或六角形的形狀,雖然本發明之有效實現亦將容許其他幾何形狀。在一目前較佳具體實施例中,漂浮管102係大約圓柱形,且漂浮管102係用氣體(即,空氣或另一安全具浮力氣體)加壓,以致當系統受錨定繫繩106限制時,組合力將會構成主要浮力以用於海流能量產生系統。
因此,藉由關閉發電機,該系統可被提升至表面以用於維護或檢查,從而減少系統上之阻力,其允許系統某些程度上朝向表面提升。藉由開啟漂浮管及/或從壓載管抽空流體,可使該單元安全及可靠地漂浮至表面以致可執行維護或檢查。
根據移動該系統之方法,繫繩106亦可加以釋放,以致該漂浮結構可被拖至或驅動朝向陸地或另一操作地點。
第2圖中描述之實例具體實施例係發電系統201的正視圖,其配有複數相對較大、緩慢移動螺旋槳206,其係佈置以與感應發電機單元204及205之軸部件機械連通。如第4A圖中可更詳盡見到,發電機單元係佈置在裝載於漂浮管102內之末端蓋單元中,以及橫跨佈置於漂浮管間之系統的格型本體部分之跨度。
螺旋槳206係針對各特定操作之規格設計,且改進效率將會基於感應發電機所需之操作頻率、周圍水流速率、環境考慮(如螺旋槳是否有魚或其他水中生物可透過其通過之開口或空洞)等等,藉由修改各螺旋槳等等之尺寸及曲率來實現。同樣的,相鄰組之螺旋槳可在相反方向(如順時針或逆時針方向)中旋轉,以促進螺旋槳前方之渦流或死區之產生,其可驅逐或協助保護海洋生物,增強螺旋槳旋轉效率等等。
最終地,螺旋槳之唯一確定操作需要係其能在需要獲得操作發電機頻率之速率下旋轉相關聯發電機軸。然而,高度需求該系統整體對於與本地海洋生物交互作用而言係保持被動,且達到最佳性能結果同時仍保持環保操作環境。
現參考第3圖,其提供先前描述為第1圖中的項目103之壓載管內部的詳圖,其中複數迷宮型隔離室係依各種氣體及液體的分離及混合可用以允許該系統中出現的平衡及浮力之更精細控制的此一方式結合,其中平衡及浮力可藉由漂浮管102獲得。
如在說明性具體實施例中可見,一在壓載管內形成之內部壓載系統301包含一空氣控制來源302(其係佈置以與一超壓止回閥流體連通)及一第一隔離室303。第一隔離室303含有一出現在該室上部分之乾氣體(如具有等於周圍外側水之壓的空氣),及一出現在該室下部分之流體(如從隔離室外側抽入之海水)。
第一隔離室303亦含有一第二空氣饋送線305,用於分布空氣至該結構之其他氣體填充隔間,以及用於混合從第一隔離室303至第二隔離室304之氣體及流體混合物的管線。第二隔離室304繼而包含一含有空氣之上部分及一含有水或類似者的下部分,其係藉由一隔離圓筒分開。在其他具體實施例中,隔離圓筒含有海水,在其上漂浮一桶流體以確保空氣及海水間之更佳隔離。
在進一步具體實施例中,第一或第二隔離室303與304係配有測試儀器(如壓力感測器或差壓感測器)以決定流體或空氣是否出現在該系統之特定空腔中。在又進一步具體實施例中,此等感測器係輸入一邏輯控制系統(未顯示),用來協助平衡之偵測與控制及推力有關測量。
使空氣前進通過箱之上部分中的系統同時確保水或其他液體保留在下部分之過程,係持續直至獲得所需平衡及控制特性。最終地,係提供一最後隔離室306,其在所述具體實施例中包含一空氣出口閥309,其係用來使空氣離開該系統,及在一些情況下使水進入系統內。
一壓力安全閥307係提供在事件內壓中,事件內壓變得如此大以致需要壓力之排放以保持系統控制的完整性,且一裝配有一螢幕以防止海洋生物意外進入之開放水流閥308係佈置在隔離箱306之一下部分中。
再次,可用阻障流體及類似者來減少空氣及水間之交互作用,且若系統係裝配有一在海水頂部漂浮的漂浮控制,則阻障流體可在逐出所有海水以後保留。
第4A圖呈現系統401之一具體實施例的俯視圖,其在此實例中包含一第一及一第二漂浮管402、403、一佈置於其間之連接暨格狀本體部分404、複數感應發電機405、406、複數螺旋槳407、及複數繫繩部件408、409。複數感應發電機405、406係策略上定位以圍繞漂浮管及本體部分;複數螺旋槳407係佈置以與發電機機械連通;複數繫繩部件408、409係佈置以與漂浮管402、403機械連通。
在第4B圖中所述之實例具體實施例中,繫繩部件408及409被結合以形成單一錨定繫繩410,其係依已知方式附接至錨定部件411。
在各種具體實施例中,錨定繫繩410進一步包含用於可變地限制及系統之構件。在各種其他具體實施例中,錨定繫繩410在一配有一繫繩終止裝置(未顯示)之錨定部件411處終止。錨定部件411包含適用於在快速移動流中維持一固定位置的任何型式之已知錨(如靜重錨或類似者),其通常係在具有因為藉由快速移動流造成之土壤腐蝕的多岩石海底的位置中發現。
在又其他具體實施例中,該站之此部分可藉由以下方式來穩固:將錨定繫繩410附接至一表面船或另一洋流能量產生裝置,或附接到例如一漂浮動態定位浮標的另一中央拋錨位置。
雖然仍有本發明之其他態樣,其基本上包含關聯水下能量產生之已知裝置的本體,其大體上(例如,輔助電源供應源、光纖控制及通訊系統、用以服務發電站之附屬遠端操作載具等等。)當然係涵蓋成為可能或用於該系統之佈署、定位、控制及操作,無須認為必須更詳細描述此等項目,因為此等系統及子系統對於熟習此項技術人士將為其已知。
雖然本發明已相對於若干範例性具體實施例詳盡描述及說明如上,熟習此項技術人士亦將可在不脫離其精神或範疇下進行對該說明之少數改變,及各種其他修改、省略及增加。
