能源翻译_风电场的风能资源-中译英

能源翻译一直是翻译行业的热门，世联上海翻译公司专业能源翻译，以下就是关于风电场的风能资源-中文翻译英文

风电场的风能资源

I.通常所说的风能是空气流动所具有的动能。风力发电就是将空气流动的动能转变为电能。大风包含着很大的能量。风速为9～10m／ S的五级风吹到物体表面上的力，每平方米面积上约10kg，风速为20m／S的九级风吹到每平米面积上的力约为50kg，风速为50～60m／s的台风这个力可达200kg。风中含有的能量比人类迄今所能控制的能量高得多，风力是地球上重要的能源之一。

风力发电机组主要包括转子（回转叶片等）、升速装置、发电机、控制装置、调速系统以及支撑铁塔等。当风力发电装置作为稳定电源经常供电时，还必须装设蓄能装置（如蓄电池）。转子上的回转叶片受风力冲动，将风力转变为回转的机械力，通过升速装置驱动发电机发电。转子一般为立式，叶片教一般为2～3片，叶片的方向与风向垂直，转速只有40～50r／min，而发电机的转速较高（例如1500r／min、50Hz的发电机），必须装设升速装置（齿轮、链条和皮带等）。控制装置包括走向装置（将转子调整对准风向）、起动和停机装置、调整风力装置（调整叶片角度以调整接受的风力）和保护装置（在过高风速时停机以及发电机保护等）。调速装置用来维持发电机定速回转。支撑铁塔用来支撑和提高转子位置，使回转叶片能接受较大风速（因风速随高度而升高）。风力发电站如图1所示。

Wind energy resource of the Wind Power Field

In general, wind energy refers to the dynamic energy resulted from the flow of air. Wind power generation is to transfer the dynamic energy resulted from the flow of air into electricity. The strong wind contains rather large energy. The force imposed upon the surface of obstacles by fresh breeze with speed of 9-10 m/s is roughly 10 kg per square meter, and the level 9 wind at speed of 20 m/s imposes a force of 50 kg/m2 upon obstacle. And similar force imposed by typhoon at speed of 50-60 m/s could be as large as 200 kg/m2. The energy contained in wind is much higher than the energy managed by mankind till today. And wind power is one of the important energy on earth.

The wind power generator consists mainly of rotor (rotary vane, etc), speed raising device, dynamo, control device, speed adjustment system and support tower, etc. When Wind power generation device serves as stable power source, there should be also accumulator device (such as storage battery). The rotary blade on the rotor is pushed by wind power and turns the wind power into rotary mechanical force which drive the dynamo to generate electricity through speed raising device. The rotor is vertical in general, and the number of vanes is normally 2 to 3 whose direction is vertical to that of wind. The rotation speed is only 40~50 r/min, while the speed of dynamo is much higher (for instance dynamo of 1500 r/min, 50 HZ), therefore a speed raising device (consisting of gear, chain and belt) must be fitted. The control device include alignment device (align the rotor with the direction of wind), start up and shut down device, wind power adjustment device (adjust the angle of vanes so as the regulate the wind force received) and protection device (shut down the unit under over speed of wind as well as dynamo protection etc.) The speed regulation device shall be employed to maintain the constant speed rotation of dynamo. The support tower is used to support and raise the position, so as to enable the rotary vane to be exposed to larger wind speed (as wind speed increases with height). A typical wind power generation station is shown in Fig.
