He has received many awards in China, including the Outstanding Young Researcher Award from Natural Science Foundation of China.
As one of the typical renewable energy sources, wind energy has experienced an immense growth with respect to both the turbine size and the market share, and led to a rapid development of the wind-power equipments. Owing to the highly volatile rough working conditions in real wind farms due to, e.g., wind gust, dust, corrosion and heavy yet unpredictable load, wind turbines are particularly prone to suffer failure and damage. Such damage can lead to a catastrophic failure of the entire wind turbine, and consequently heavy investment and productivity losses. Therefore, wind turbine condition monitoring and diagnosis become crucial. In this presentation, the development status of the wind energy all over the world, particularly in China, is briefly summarized. The research situations of the existing condition monitoring and fault diagnosis methods for the main failure components of wind turbines are then analyzed, such as gearboxes, bearings and blades. Finally, the problems to be solved and new development trend for wind power equipment monitoring and fault diagnosis are discussed.
