Currently, all floating wind turbines served on the sea are positioned by the mooring system. A novel conceptual design of using the dynamic positioning system (DPS) to position the floating wind turbine is proposed in this paper. Certain benefit aspects of the proposed conceptual design are elaborated. A time domain simulation for the designed floating wind turbine is conducted to demonstrate its effectiveness. It is obtained from the results that approximately 1/2 of the generated energy is utilized by the DPS to keep the floating wind turbine positioned if current forces are not considered, while the ratio becomes 4/5 if current load effects are taken into account. Thus, the proposed conceptual design is demonstrated to be feasible in the view of conservation of energy. The impact of several primary design variables, such as the diameter of the wind turbine rotor, the diameter of the thruster and the wind speed, on the power ratio is specifically investigated. To make the conceptual design more convincible, several representative operational situations of the floating wind turbine in its lifetime are analyzed. It can be found that the situations that the consumed power is larger than the generated power can be effectively tackled by the stored hydrogen converted in the far long period of operation of the wind turbine in rated wind speed. Considering the proposed concept has particular benefits that cannot be replaced by conventional moored floating wind turbines, further research on the novel concept is warranted.

当前，所有在海上使用的浮动式风力涡轮机都由系泊系统定位。本文提出了一种利用动态定位系统（DPS）对浮动风力发电机进行定位的新颖概念设计。拟议的概念设计的某些好处方面得到了阐述。对所设计的浮动风力涡轮机进行了时域仿真，以证明其有效性。从结果中可以得出，如果不考虑电流力，DPS会利用大约1/2的发电能量来保持浮动风力涡轮机的位置，而如果考虑电流负载效应，则该比例将变为4/5。因此，从节约能源的角度出发，所提出的概念设计被证明是可行的。几个主要设计变量的影响，具体研究了诸如风力涡轮机转子的直径，推进器的直径和风速之类的功率比。为了使概念设计更具说服力，分析了浮动风力涡轮机在其使用寿命中的几种典型运行情况。可以发现，通过在额定风速下的风力涡轮机的长远运行期间转换的存储的氢，可以有效地解决消耗功率大于发电功率的情况。考虑到所提出的概念具有无法用传统的系泊浮式风力涡轮机替代的特殊优势，因此有必要对该新概念进行进一步的研究。为了使概念设计更具说服力，分析了浮动风力涡轮机在其使用寿命中的几种典型运行情况。可以发现，通过在额定风速下的风力涡轮机的长远运行期间转换的存储的氢，可以有效地解决消耗功率大于发电功率的情况。考虑到所提出的概念具有无法用传统的系泊浮式风力涡轮机替代的特殊优势，因此有必要对该新概念进行进一步的研究。为了使概念设计更具说服力，分析了浮动风力涡轮机在其使用寿命中的几种典型运行情况。可以发现，通过在额定风速下的风力涡轮机的长远运行期间转换的存储的氢，可以有效地解决消耗功率大于发电功率的情况。考虑到所提出的概念具有无法用传统的系泊浮式风力涡轮机替代的特殊优势，因此有必要对该新概念进行进一步的研究。可以发现，通过在额定风速下的风力涡轮机的长远运行期间转换的存储的氢，可以有效地解决消耗功率大于发电功率的情况。考虑到所提出的概念具有无法用传统的系泊浮式风力涡轮机替代的特殊优势，因此有必要对该新概念进行进一步的研究。可以发现，通过在额定风速下的风力涡轮机的长远运行期间转换的存储的氢，可以有效地解决消耗功率大于发电功率的情况。考虑到所提出的概念具有无法用传统的系泊浮式风力涡轮机替代的特殊优势，因此有必要对该新概念进行进一步的研究。
