摘要
偏航系统是风电机组实现高效风能捕获的关键子系统,其可靠性直接影响机组发电效率与运行安全。以某风电场JXX1机组偏航断齿故障为例,通过现场调查、失效件分析及理论计算,系统探讨了故障的根因,并提出针对性解决方案。研究表明:主机架变形导致的偏航齿隙异常是主要诱因(实测变形量达9mm,标准值≤1.15mm),极端运行工况(瞬时转速超额定值12.7倍)与作业方法不规范加剧了齿轮损伤。基于分析结果,提出加强主机架形位公差控制(平面度≤0.06mm)、优化卡簧抗脱落设计(双卡簧结构提升安全阈值)、引入智能齿隙监测系统等措施。经实践验证,上述措施可降低断齿故障率65%,为风电行业提供了从设计、制造到运维的全生命周期解决方案。未来研究需要结合智能预测技术,提升偏航系统的健康管理水平。
The yaw system is a critical subsystem for wind energy generation systems to achieve efficient wind energy capture,and its reliability directly affects the power generation efficiency and operational safety of wind turbines.Taking the yaw gear tooth fracture fault of the JXX1 system in a wind farm as an example,the root causes of the fault were systematically investigated through field surveys,analysis of the failed part,and theoretical calculations,and targeted solutions were proposed.The study reveals that abnormal yaw gear backlash caused by main frame deformation is the primary contributing factor(the measured deformation reached 9 mm,while the standard value is≤1.15 mm).Besides,extreme operating conditions(the instantaneous rotational speed exceeding the rated value by 12.7 times)and non-standard operating practices exacerbated the gear damage.Based on the analysis results,measures such as strengthening the control of main frame geometric tolerances(flatness≤0.06 mm),optimizing the anti-disengagement design of circlips(dual-circlip structure to enhance the safety threshold),and introducing an intelligent gear backlash monitoring system are proposed.Practical verification shows that these measures can reduce the gear fracture failure rate by 65%,providing a full lifecycle solution for the wind power industry from design and manufacturing to operation and maintenance.Future research needs to integrate intelligent prediction technologies to enhance the health management level of the yaw system.
