摘　　要：兆瓦级风力机的液压系统一旦发生故障,维修难度较大。了解大功率风力机的常见故障及其原因,具有十分重要的意义。重视小故障、故障早期阶段的发现和排除,故障诊断和排除时注意对预兆、运行记录的分析。介绍了一种典型的1MW风力机型号的液压系统维护常见故障实例,并提出其液压系统结构的改进方案。Once is hydraulic system of MW degree wind turbine fault, the maintenance is very difficult. It is very important to study the cause of the failure of hydraulic system of wind turbine, and pay attention to small fault, found any information that result in fault probably in the early days, and as well as pay attention to of the operation records. The paper also introduces hydraulic system of a 1 MW model wind turbine examples, and represent the structure improvement plan of the hydraulic system of wind turbine.
