A Wind Turbine is a device which uses kinetic energy of blowing wind to generate electrical energy. A wind turbine consists of two or three rotor blades which are mounted on a rotor. When the blowing wind exerts a lift and drag force on these blades, the rotor starts rotating. A main shaft is attached to the rotor which is connected to an electric generator on the other end. The generator produces electricity when driven by the wind turbine.
风力发电机是利用风的动能来产生电能的装置。风力涡轮机由安装在转子上的两个或三个转子叶片组成。当吹来的风对这些叶片施加升力和阻力时，转子开始旋转。主轴连接到转子，转子的另一端连接到发电机。发电机在风力涡轮机的驱动下产生电力。
Depending on the axis of rotation, the wind turbines are classified into two types:
根据旋转轴的不同，风力发电机分为两种类型：
Horizontal Axis Wind Turbine
水平轴风力发电机
Vertical Axis Wind Turbine
垂直轴风力发电机
What is a Horizontal Axis Wind Turbine (HAWT)?
什么是水平轴风力发电机 (HAWT)？
The type of wind turbine in which the axis of its rotation is parallel to the flow of air stream is known as a horizontal axis wind turbine or HAWT. The horizontal axis wind turbine is the most successful type of wind turbine and it is most widely used worldwide. The horizontal axis turbine is mainly used for the generation of electricity for commercial purposes in different parts of the world.
旋转轴与气流平行的风力涡轮机类型被称为水平轴风力涡轮机或HAWT。水平轴风力发电机是最成功的风力发电机类型，在全球范围内应用最广泛。水平轴水轮机主要用于世界各地商业用途的发电。
The horizontal axis wind turbines have comparatively low cuts in wind speed and have a high power coefficient. However, the design of HAWT is relatively more complicated and costly because it requires a gearbox and an electric generator placed at the top of the tower. The major components that a horizontal axis wind turbine consists of are turbine blades, hub, gearbox, generator, tower, nacelle, and yaw control (to orient the turbine in the direction of wind).
水平轴风力发电机的风速衰减较小，功率系数较高。然而，HAWT 的设计相对更复杂且成本更高，因为它需要在塔顶放置变速箱和发电机。水平轴风力涡轮机的主要部件包括涡轮叶片、轮毂、齿轮箱、发电机、塔架、机舱和偏航控制装置（用于使涡轮机沿风向定向）。
Advantages:
Efficiency: HAWTs are more efficient than other types of wind turbines because they can generate more electricity from the same amount of wind.
Easy Maintenance: HAWTs are easier to maintain than other types of wind turbines because their components are easily accessible.
Larger Blades: HAWTs can have much larger blades than other types of wind turbines, which means they can generate more electricity.
优点：
效率：HAWT 比其他类型的风力涡轮机效率更高，因为它们可以从相同数量的风中产生更多的电力。
易于维护：HAWT 比其他类型的风力涡轮机更易于维护，因为其组件易于检修。
更大的叶片：HAWT 可以比其他类型的风力涡轮机拥有更大的叶片，这意味着它们可以产生更多的电力。
Disadvantages:
Noise: HAWTs can be noisy, which can be a problem for people living near wind farms.
Large Size: HAWTs are usually quite large, which means they require a lot of space to operate. This can be a problem in densely populated areas.
Bird and Bat Mortality: HAWTs can pose a risk to birds and bats, which can collide with the spinning blades.
缺点：
噪音：HAWT 可能会产生噪音，这对于居住在风电场附近的人们来说可能是一个问题。
尺寸大：HAWT通常很大，这意味着它们需要大量的空间来运行。在人口稠密的地区这可能是一个问题。
鸟类和蝙蝠死亡：HAWT 可能会对鸟类和蝙蝠构成风险，因为它们可能会与旋转的叶片发生碰撞。
