摘要: | 為開發黑潮發電以擷取可觀之再生能源,如何將發電機組固定於深水海底並抵擋強勁水流,將成為這項技術最大的挑戰之一。本文探討不同的錨碇方式,考慮初期以10MW輸出功率離岸5公里規模的先導型海流電廠,也檢討以25平方公里海域裝置渦流發電機網擷取1GW電能的考量下,進行錨碇系統結構設計與建造可行性研究。本文所自行設計之錨碇系統分兩種管架結構設計與一球接頭圓管結構設計,分別進行強度分析與探討,比較管架結構於球接頭圓管結構之優劣與可行性,並以纜索方程式估算纜索錨碇點之張力與纜索形狀,來決定合適之錨碇方式。 For the exploitation of the huge ocean energy, development of Kuroshio current generator network system may be a chance for Taiwan. One of the biggest challenges of the ocean energy technology is how to moor the generators on the deep sea and resist the strong currents to keep them in right positions. This study explores different mooring systems for a pilot marine current power plant of 10MW located at 5km off shore. The feasibility of the design and construction of a mooring system for a current power generator of 1GW installed on a sea area of 25 square kilometers was considered. The design of the mooring system in this work contains two kinds of frame structures and a spherical-joint connected-pipe structure. The stress analysis for three designs were conducted to compare their advantages. The tension and the shape of the cable in the mooring system were analyzed to examine the mooring force of connected points and the floating condition of mooring structures. |
