基于PLC的风力发电机偏航控制系统设计

se the yaw mechanism is installed at the bottom of the nacelle and connected to the nacelle through the yaw bearing. When the wind direction changes, the wind vane sends a signal to the control system, which activates the driving device. The small gear rotates on the large ring gear, causing the nacelle to rotate, aligning the wind turbine with the wind direction. When the direction of rotation of the nacelle is detected by the proximity switch, when the nacelle reaches the maximum yaw angle in the same direction, the limit switch will promptly send a signal to the control device, which will quickly send a signal to stop the unit and reverse the unlashing, thus achieving yaw control to keep the wind turbine always facing the wind. Based on the working principle of the yaw system, the basic problems to be solved by this design are: 1. design of a dual control system for automatic yaw control and manual yaw control; 2. design of the braking device of the yaw system and the control method for the lashing and unlashing protection device; 3. understanding the function, working principle and control method of the yaw hydraulic system; 4. writing the drive control program, lashing and unlashing protection program. Keywords: wind direction, automatic yaw control, wind vane, yaw motor. 本文档描述的是一篇本科毕业论文，题为“基于 PLC 的风力发电机偏航控制系统设计”。论文首先介绍了风力发电技术在全球范围内备受关注的背景，然后详细介绍了偏航控制系统的工作原理和设计要解决的基本问题。该论文深度分析了偏航控制系统的设计原理和程序编写，对偏航系统的制动装置、扭缆、解缆保护装置等进行了深入探讨。通过该论文，读者可以全面了解基于 PLC 的风力发电机偏航控制系统的设计原理和方法，对于从事相关研究或者工程实践的人员具有一定的参考意义。
