摘要
为提高风机偏航液压制动系统的响应性能和环境适应性,在常规偏航制动器的基础上改进得到一种带压力控制功能的新型制动器。以2 MW和8 MW风机为例,阐述了带压力控制的偏航制动器用于偏航液压制动系统设计时的主要方法及有益效果,并对使用和未使用该制动器的偏航液压制动系统进行了全压制动和阻尼制动工况的仿真分析与对比。结果表明,带压力控制的偏航制动器可显著提高制动系统的响应速度和低温稳定性,为风机偏航制动器及偏航液压制动系统的优化设计提供了参考。
In order to improve the response performance and environmental stability of wind turbine yaw hydraulic brake system,a new type of brake with pressure control function was improved on the basis of conventional yaw brake.Taking 2 MW and 8 MW wind turbines as examples,the main methods and beneficial effects of the pressure-controlled yaw brake used in design of yaw hydraulic brake system were expounded,and the simulation analysis and comparison of full pressure braking and damping braking conditions were carried out for yaw hydraulic braking system with and without the brake.The results show that pressure-controlled yaw brake can signifi⁃cantly improve the response speed and low temperature stability of braking system.The study provides a reference for optimal design of wind turbine yaw brake and yaw hydraulic brake system.
