Abstract

A wind turbine has an impeller surrounded by a shroud. The shroud is formed from inflatable components extending between two rigid structural members. When inflated, the shroud acts to increase the energy generated by the impeller. Under adverse wind conditions, the inflatable components can be deflated to reduce surface area and wind load on the turbine.

技术领域 FIELD

[0002] 本公开涉及具有可充气部件的风力涡轮机。 [0002] The present disclosure relates to a wind turbine inflatable member. 背景技术 Background technique

[0003] 用于发电的传统风力涡轮机通常具有配置成类似螺旋桨的两到五个敞开式叶片(open blade),这些叶片安装在水平轴上,该水平轴安装在驱动发电机的齿轮箱上。 [0003] Traditional wind turbine for power generation generally have two to five open configured like the screw propeller blades (open blade), the blade mounted on a horizontal axis, the horizontal shaft mounted on the gear box drives a generator. 这种涡轮机通常称作水平轴风力涡轮机或HAWT。 Such turbines are generally known as horizontal axis wind turbine or HAWT. 虽然HAWT已实现了广泛使用,但是其效率还未最优化。 Although HAWT has achieved widespread use, but its effectiveness has not been optimized. 特别地,HAWT在捕获通过该涡轮机的风的潜能中的效率不会超过59. 3%的贝兹极限。 In particular, HAWT capture efficiency by the wind turbine does not exceed the potential of the Betz limit of 59.3%.

[0004] 传统的风力涡轮机具有三个叶片,并通过计算机控制的马达被朝着风定向或被指向风。 [0004] Traditional wind turbines have three blades and are oriented or pointed into the wind towards the wind by computer controlled motors. 这些涡轮机典型地需要高度在60米至90米范围的支撑塔架。 These turbines typically require a supporting tower height in the 60-90 m range. 叶片通常以大约IOrpm至22rpm的转速转动。 Blades generally rotate at a speed of about 22rpm to IOrpm. 尽管一些设计可以直接驱动环形发电机,但是一般还是使用齿轮箱来加速以驱动发电机。 Although some designs may directly drive a ring generator, it is generally used to speed gearbox to drive a generator. 一些涡轮机以恒速运行。 Some turbines operate at constant speed. 然而,更多能量能够通过使用变速涡轮机和将涡轮机与发电机连接的固态功率变换器(solid state power converter)而被收集。 However, more energy can be collected by using a variable speed turbine and a solid state power converter (solid state power converter) turbine connected to a generator.

[0005] 存在与HAWT的结构和操作相关的许多问题。 [0005] There are many problems associated with the construction and operation of a HAWT. 高塔架和长叶片难以运输。 High towers and long blades difficult to transport. 要求大而重的塔架结构以支撑重的叶片、齿轮箱和发电机。 It requires a large and heavy tower structure to support the weight of the blade, gearbox and generator. 安装需要非常高且昂贵的吊车以及熟练的操作工人。 Installation requires a very high and expensive cranes and skilled workers. 在操作中,HAWT需要另外的偏航(yaw)控制机构以使叶片转向风。 In operation, HAWT need additional yaw (Yaw) the steering control means so that the wind vane. HAWT典型地在其翼型(airfoil)上具有大迎角(angle of attack),该大迎角使得翼型在气流中不产生可变变化。 HAWT typically have a high angle of attack (angle of attack) on which the airfoil (airfoil), the angle of attack of the airfoil such that no change in the gas flow variable. HAWT在地面附近紊流的风中难以操作。 HAWT difficult to operate in a turbulent wind near the ground. 在舱(nacelle)和叶片上堆积的冰可能导致功率减小和安全问题。 On the cabin (nacelle) and the blades of ice accumulation can lead to power reduction and security issues. 高的HAWT会影响机场雷达。 High HAWT affect airport radar. 其高度也使其横跨大区域突兀可见,破坏了景观,有时引起了当地人的抗议。 It also makes it highly visible across large areas unexpected, destroyed the landscape, sometimes caused protests of local people. 最后,顺风方向的变型遭受由紊流引起的疲劳和结构故障。 Finally, variations downwind suffer fatigue and structural failure caused by the turbulence.

[0006] 期望减小风力涡轮机的尺寸并且期望减小不期望的风力负载下的风力涡轮机表面区域。 [0006] desirable to reduce the size of the wind turbine and it is desirable to reduce the surface area of ​​the wind turbine at wind load undesirable.
