摘　　要：风力发电系统往往安装在偏僻的、难以接近的或者气候不适合人类长期逗留的地域,传统的计划维修和事后维修方式不能满足要求。为保证风力发电系统可靠稳定运行,降低系统的维护成本,对其进行状态监测与故障诊断是十分必要的。论文针对风力发电系统中的主要部件,即齿轮箱、发电机、电力电子装置、叶片等的故障,对现有故障诊断方法进行了分类与综述,为提高对风力发电系统的可靠性、降低成本,促进其工程化进程提供了有效的参考。Wind power systems are often installed where is remote, inaccessible or the climate is not suitable for human to stay for long time. So the traditional scheduled maintenance and breakdown maintenance can not meet the demands. It is very essential to ensure re- liable and stable operation, and to reduce the cost of maintenance, condition monitoring and fault diagnosis of wind power system. The existing fault diagnosis methods for the main failure components of wind power system, including gear boxes, generator, power electronic devices, blade and so on, were introduced and classified. This work will provide an effective reference to the improvemet of the reliabil- ity of wind power system, reduction of cost and promoting the engineering process.
