基于PLC风机偏航系统解缆控制 I
摘 要
风能作为可再生能源中发展最快的清洁能源，其具有清洁，无污染，安全，储量丰富的特点，受到世界各国的普遍重视，是最具有大规模开发和商业发展前景的可再生能源。当前，中国风电市场蓬勃发展，由此带动中国风机制造产业呈现欣欣向荣的发展势态。然而，风电的超速发展可能造成很多隐患。其中设备故障而浪费大量人力资源维护的隐患应引起我们足够的重视。本文以风力发电模型机的解缆系统解缆控制为研究对象，采用PLC控制器作为上位机控制解缆装置，根据限位开关的信号确定解缆的方向，启动执行相应的顺时针方向或逆时针方向机舱解缆程序。解决风力发电机组存在的累计纽缆次数较多、因纽缆造成的偏航时间较长、导致风力发电机组发电的停机解缆的技术问题。

ABSTRACT
Wind power as the fastest growing renewable energy and clean energy, which has a clean, pollution-free, safe, abundant features, has gotten great attention by the countries in the world. Wind power is the most large-scale development and commercial prospects for development of renewable energy. At present, Chinese wind power market led the Chinese manufacturing industry explosion development. However, wind power overspeed developing may cause a lot of hidden dangers. Because of equipment failure waste human resources to maintain a large number of hidden dangers should arouse our attention. This article is based on the model of wind power untwist system as the research object. Adopt PLC controller to untwist, According the limit switch signals to determine the untwist direction. Start the corresponding compiler to solve the problems as existing wind turbine twist and Yaw time too much.
Key words: wind power, PLC, yaw motor, untwist
