摘要
在造波水槽内对后弯管浮体模型进行了波能转换性能的试验研究。通过对比试验,选定了最佳浮体模型——前方后圆浮室后伸型后弯管浮体。波能转换效率达ηA= 73.3% 。给出了该浮体模型的性能曲线及其无因次特性。测定了该模型最大锚泊力Fmax随浮体参数的变化规律。设计制造了5kW 后弯管波力发电浮体。该机组采用0.8m 直径的对称翼透平和无刷爪极发电机,输出直流电。采用单点锚泊系统,在珠江口桂山岛西南面海域进行海上试验。实测数据表明,海上试验瞬时功率大于5kW,超过机组设计额定值。
An experimental research on the wave energy conversion performance of a 1/10 BBDB model was made in the wave tank. By a comparison study on 10 model options, an optimal BBDB, the backward extended BBDB with a rectangular front and cylindrical back floating room, was obtained. The efficiency of the wave energy conversion reaches η A =73 3%. Its performance curves and non dimension performance are presented. The maximum mooring force variation curves with the parameters of the floating body are plotted. On the basis of the optimum floating body model, a backward extended BBDB with a rectangular front and cylindrical back floating body is designed and manufactured. Its width is 5 1 m; the length of the part above the water is 6 63 m; the length of the part below the water is 9 23 m; Its height/ (including the lamp shelf) is 8 4m; and the total weight is 19 6 tons. A 5kW wave activated generating set is installed at the center of the top of the floating body. The set use a 0 8m diameter Wells′ turbine and a brushless claw pole generator, which produces direct current. The single point mooring system is used. The 5kW BBDB WGD is moored in the southwest waters of Guishan island in the estuary of Pearl River as the experiment object. The experiment data indicate that the instantaneous power is greater than 5kW, over the designed rated power.
