新型圆柱型离岸风机基座的设计与分析

Design and analysis of a New Spar offshore wind base

为了实现离岸风机的稳定性提高,通过对传统离岸风机基座存在的优缺点分析,再结合几代Spar平台基座的优点,提出一种新型圆柱型离岸风机基座设计。对新型离岸风机基座细致剖析,再和传统两代离岸风机基座进行频域分析。分析结果表明:使用垂荡板和增加垂荡板的数量均能使离岸风机的稳定性能提高,增加垂荡周期,使风机具有更好的稳定性。

Aiming at improving the stability of offshore, wind, we analyze the advantages and disadvantages of traditional offshore wind as well as the advantages of several ge.nerations of Spar platform base. So we come up with a design of a New Spar offshore windy base. We did an in-depth analysis of the new offshore wind base. By means of frequency domain analysis on two generations of traditional offshore wind bases and the new one, we found the main influences. The analytic resuh shows that the adoption of heave-damping plate as well as increasing the quantity of heave-damping plate can improve the stability of offshore wind, Increasing the heaving cycle, making the stability of wind better.
