Description

一种多转子风力发电系统 A multi-rotor of the wind power generation system

技术领域 FIELD

[0001] 本发明属于风能利用领域,涉及一种多转子风力发电系统。 [0001] The present invention belongs to the field of wind energy utilization, to a multi-rotor of the wind power generation system. 背景技术 Background technique

[0002] 随着世界性能源危机和全球环境污染加剧,许多国家都更加重视洁净的可再生能源的研究、开发和利用。 [0002] As the global energy crisis and global environmental pollution, many countries have more emphasis on clean and renewable research, development and use of energy. 全球风能理事会指出,风力发电技术相比其它可再生能源技术而言更成熟,其效率也更高,产业前景最好,其开发利用增长率远高于常规能源,风力发电技术是世界上发展最快的可再生能源技术之一。 Global Wind Energy Council pointed out that wind power technology is more mature compared to other renewable energy technologies, its efficiency is higher, the best prospects for the industry, its development and utilization growth rate is much higher than conventional energy, wind power technology is the world's one of the fastest growing renewable energy technology.

[0003] 风轮是风能转换为机械能的核心部件,因此叶片的性能决定风电机组的性能,叶片在设计寿命期内的安全稳定运行至关重要。 [0003] The wind turbine is a wind energy into mechanical energy of the core member, and therefore determines the performance of wind turbine performance, security and stability of the blade of the blade is essential to run in the design lifetime. 水平轴风力发电机的叶片在旋转过程中,受水平推力、惯性力和重力的综合作用。 During the rotation, the combined effect of the horizontal axis wind turbine blade by the horizontal thrust, gravity and inertial forces. 受风切变影响,水平推力的大小始终变化,无论对叶片还是传动系统和塔架都产生大的交变载荷;惯性力的方向随时变化;重力在叶片根部产生一个与旋转频率同频率的交变载荷。 Influence by wind shear, the size of the horizontal thrust always changes, or both the blade and the tower are a large drive system alternating load; subject to change the direction of inertial force; gravity and deposit a rotational frequency of the same frequency at the blade root variable load. 上述三个交变载荷以及由此产生的振动是叶片破坏的主要原因。 The three alternating load and resulting vibration is the main cause blade failure.

[0004] 风力发电机单机功率越做越大,目前国际上比较一致的看法是:单机功率越大, 成本越低,其原因是一般认为风力机功率越大,所需的风力机数目越少,需要维修的部件越少,成本越低。 [0004] wind turbines stand-alone power bigger and bigger, more consistent view on the current international is: the larger the single power, the lower the cost, the reason is generally believed that the larger the wind turbine power, the fewer the number of wind turbines needed , fewer parts need maintenance, the lower the cost.

[0005] 实际上,由于受建筑物和地面的摩擦作用,随着高度的增加,风速逐渐增大,这种现象称之为风切变,叶片在回转平面内处于不同位置时,风速会有差异,因而在回转平面垂直方向上叶片承受的水平推力和回转力矩的大小会不同,导致叶片受到疲劳载荷。 [0005] In fact, due to the friction of the building and the ground, with increasing height, wind speed is gradually increased, a phenomenon known as wind shear, the blades in different positions in the plane of rotation, the wind speed will be differences, and thus in a plane perpendicular to the rotation direction of the blade to withstand horizontal force and the size of the swing moment will be different, resulting in the blades being fatigue loads. 同时,重力也会在叶片上产生交变载荷。 Meanwhile, gravity will produce alternating load on the blade. 因此,叶片越长,重量越重,受风切变和重力载荷的影响越大,导致叶片所承受的交变载荷越大,叶片越容易发生破坏。 Thus, the longer the blade, the heavier the weight, the greater the influence of wind shear and a heavy load, resulting in greater blade is subjected to alternating load, the more prone to damage the blade. 目前,大型风力发电机叶片破坏的报道还不多见,主要是因为安装时间短,问题还没有完全暴露,若干年后,也许会大面积爆发。 Currently, large-scale wind turbine blade damage reports still rare, mainly because of the short installation time, the problem has not been fully exposed, after a few years, perhaps a large area of ​​the outbreak. 一旦出现问题,风电场由于停机、停电造成经济损失,再算上维修、吊装及更换零部件、超限运输、重复安装等等花费,加之风机大多安装在偏远或者交通不便的地区,吊装拆卸难度大,最后付出的代价巨大。 If there are problems, the wind farm due to the shutdown, power outage caused economic losses, and then count maintenance, lifting and replacement parts, limited transportation, and so repeat the installation cost, coupled with the fan installed in the most remote or inaccessible areas, lifting disassembly difficulty big, huge final pay. 因此,虽然风电机组的制造成本随功率增加而降低,但考虑到后期的维修等费用,其总成本反而会上升。 Thus, while the manufacturing cost of wind turbines with power increase and reduce, but considering the cost and maintenance of late, but the total cost will rise. 另一方面,巨型风电机组其叶片长度将达到60-70m,陆上运输、安装极为困难,安装用的吊车容量将超过1200-1400t,很多地区不具备这个条件,从而限制了巨型风电机组的使用。 On the other hand, its length giant wind turbine blades reach 60-70m, land transportation, installation is very difficult, mounting crane capacity will exceed 1200-1400t, many areas do not have this condition, thereby limiting the giant WTG .
