摘要
变桨距系统是风力发电机控制的关键技术之一。在国内外研究的基础上提出一种新型的变桨距系统,该系统采用液压变桨距机构来实现桨距角的改变。在安全液压缸和控制液压缸的共同作用下,该套系统相对其他变桨距机构更具有变桨力矩大、变桨精度高、易于控制、叶片振动小等优点。
Pitch -control is one of the key technology of wind turbine. A new pitch -controlled system was given based on the research at home and abroad, and hydraulic - pitch - controUed structure was used to change the pitch - angle. Affected by the security hydraulic cylinder and control hydraulic cylinder, this system is easy to control and has a large moment, good precision,small vibration of pitch -control compared with another systems.
