海上风电机的抗台风设计

吴金城,张容焱,张秀芝

《中国工程科学》 2010年第12卷第11期页码 25-31

摘要：

风电机组的制造成本和使用寿命取决于运行中的疲劳载荷、极端载荷和设计所依据的标准。目前，设计风电机组依据的大都是以欧洲环境特征为背景的标准，不加考虑地在台风地区使用会增加风险或制造成本。只有充分认识台风的气候特征和对风电机组的破坏机理，综合考虑，才能设计制造既能抗台风又能确保项目经济可行的风电设备。

试析海上风机在强台风下叶片受损风险与对策——考察红海湾风电场的启示

王景全,陈政清

《中国工程科学》 2010年第12卷第11期页码 32-34

摘要：

2003年9月近海丘陵区风电场——汕尾红海湾风电场风机叶片被台风“杜鹃”吹坏。从破坏形式可以断定叶片曾发生大幅度扭转颤振而且与不利地形有关。从这一实例来看，同等强度台风情况下海上风机叶片受损的风险可能低于海岸风机，因为海面平坦，不具备风向局部变化条件。此次风灾也表明，保持风机处于停转顺桨，但可偏航的暂停状态是叶片防损的关键。

Himani,Ratna DAHIYA

《能源前沿（英文）》 2016年第10卷第3期页码 286-297 doi: 10.1007/s11708-016-0419-5

摘要： The intend of this paper is to give a description of the realization of a low-cost wind turbine emulator(WTE) with open source technology from graze required for the condition monitoring to diagnose rotor and stator faults in a wind turbine generator (WTG). The WTE comprises of a 2.5 kW DC motor coupled with a 1 kW squirrel-cage induction machine. This paper provides a detailed overview of the hardware and software used along with the WTE control strategies such as MPPT and pitch control. The emulator reproduces dynamic characteristics both under step variations and arbitrary variation in the wind speed of a typical wind turbine (WT) of a wind energy conversion system (WECS). The usefulness of the setup has been benchmarked with previously verified WT test rigs made at the University of Manchester and Durham University in UK. Considering the fact that the rotor blades and electric subassemblies direct drive WTs are most susceptible to damage in practice, generator winding faults and rotor unbalance have been introduced and investigated using the terminal voltage and generated current. This wind turbine emulator (WTE) can be reconfigured or analyzed for condition monitoring without the need for real WTs.

Optimization design of spar cap layup for wind turbine blade

Jie ZHU, Xin CAI, Pan PAN, Rongrong GU

《结构与土木工程前沿（英文）》 2012年第6卷第1期页码 53-56 doi: 10.1007/s11709-012-0147-9

摘要： Based on the aerodynamic shape and structural form of the blade are fixed, a mathematical model of optimization design for wind turbine blade is established. The model is pursued with respect to minimum the blade mass to reduce the cost of wind turbine production. The material layup numbers of the spar cap are chosen as the design variables; while the demands of strength, stiffness and stability of the blade are employed as the constraint conditions. The optimization design for a 1.5 MW wind turbine blade is carried out by combing above objective and constraint conditions at the action of ultimate flapwise loads with the finite element software ANSYS. Compared with the original design, the optimization design result achieves a reduction of 7.2% of the blade mass, the stress and strain distribution of the blade is more reasonable, and there is no occurrence of resonance, therefore its effectiveness is verified.

Effects of elastic support on the dynamic behaviors of the wind turbine drive train

Shuaishuai WANG, Caichao ZHU, Chaosheng SONG, Huali HAN

《机械工程前沿（英文）》 2017年第12卷第3期页码 348-356 doi: 10.1007/s11465-017-0420-7

摘要：

The reliability and service life of wind turbines are influenced by the complex loading applied on the hub, especially amidst a poor external wind environment. A three-point elastic support, which includes the main bearing and two torque arms, was considered in this study. Based on the flexibilities of the planet carrier and the housing, a coupled dynamic model was developed for a wind turbine drive train. Then, the dynamic behaviors of the drive train for different elastic support parameters were computed and analyzed. Frequency response functions were used to examine how different elastic support parameters influence the dynamic behaviors of the drive train. Results showed that the elastic support parameters considerably influenced the dynamic behaviors of the wind turbine drive train. A large support stiffness of the torque arms decreased the dynamic response of the planet carrier and the main bearing, whereas a large support stiffness of the main bearing decreased the dynamic response of planet carrier while increasing that of the main bearing. The findings of this study provide the foundation for optimizing the elastic support stiffness of the wind turbine drive train.

锚杆关键参数对锚杆重力式海上风机基础承载特性的影响

王尔贝,陈锐,霍宏斌

《中国工程科学》 2014年第16卷第8期页码 69-73

摘要：

针对最近提出的锚杆重力式海上风机基础，采用有限元分析软件ABAQUS研究了锚杆的关键参数对此新型基础承载特性的影响。结果表明：增加锚杆数量可以提高基础的承载力并减小单根锚杆的轴力。但是当锚杆数量增加到一定程度时，会使其间距过小，引起地基中应力的叠加，降低锚杆群的承载效率，因此锚杆数量存在上限。基础承载力几乎随锚杆直径的增加呈线性提高，锚杆直径越大对基础稳定越有利，因此在可行的情况下，应尽可能地选用大直径锚杆。锚杆环直径的增大相当于增大了基础抗倾覆力矩的力臂，因此对弯矩承载力是有利的，但由于锚杆群对地基等效刚度的改变，竖向承载力会随着锚杆环直径的增大而先增后减。设计时要综合考虑各个承载力因素，选用合适的锚杆环直径。

genetic algorithms based structural optimization and experimental investigation of the planet carrier in windturbine gearbox

Pengxing YI,Lijian DONG,Tielin SHI

《机械工程前沿（英文）》 2014年第9卷第4期页码 354-367 doi: 10.1007/s11465-014-0319-5

摘要：

To improve the dynamic performance and reduce the weight of the planet carrier in wind turbine gearbox, a multi-objective optimization method, which is driven by the maximum deformation, the maximum stress and the minimum mass of the studied part, is proposed by combining the response surface method and genetic algorithms in this paper. Firstly, the design points’ distribution for the design variables of the planet carrier is established with the central composite design (CCD) method. Then, based on the computing results of finite element analysis (FEA), the response surface analysis is conducted to find out the proper sets of design variable values. And a multi-objective genetic algorithm (MOGA) is applied to determine the direction of optimization. As well, this method is applied to design and optimize the planet carrier in a 1.5 MW wind turbine gearbox, the results of which are validated by an experimental modal test. Compared with the original design, the mass and the stress of the optimized planet carrier are respectively reduced by 9.3% and 40%. Consequently, the cost of planet carrier is greatly reduced and its stability is also improved.

A complete modeling and simulation of DFIG based wind turbine system using fuzzy logic control

Abdelhak DIDA,Djilani BENATTOUS

《能源前沿（英文）》 2016年第10卷第2期页码 143-154 doi: 10.1007/s11708-016-0402-1

摘要： The current paper talks about the variable speed wind turbine generation system (WTGS). So, the WTGS is equipped with a doubly-fed induction generator (DFIG) and two bidirectional converters in the rotor open circuit. A vector control (VC) of the rotor side converter (RSC) offers independent regulation of the stator active and reactive power and the optimal rotational speed tracking in the power maximization operating mode. A VC scheme for the grid-side converter (GSC) allows an independent regulation of the active and reactive power to exchange with the grid and sinusoidal supply currents and keeps the DC-link voltage constant. A fuzzy inference system (FIS) is adopted as an alternative of the conventional proportional and integral (PI) controller to reject some uncertainties or disturbance. The performances have been verified using the Matlab/Simulink software.
