The invention provides a wind turbine generator system driving chain health state evaluation system and method and relates to the technical field of wind turbine generator system driving chain monitoring. The system comprises multiple sensors distributed at wind turbine generator system driving chains; the multiple sensors are connected with cloud processing devices; the cloud processing devices are connected with fiber switches; the fiber switches are connected with a remote server through a fiber ring network; the remote server is connected with a remote display terminal through Internet; and the multiple sensors comprise vibration sensors and temperature sensors. The cloud processing devices respectively obtain vibration data and temperature data of each position of the wind turbine generator system driving chains according to the vibration sensors and the temperature sensors; online operation health states of the wind turbine generator system driving chains, fault positions and residual lives are determined through a preset health evaluation model database; and the online operation health states of the wind turbine generator system driving chains, the fault positions and the residual lives are transmitted to the remote server through the fiber switches and the fiber ring network, and the remote display terminal displays the information.
Description
technical field [0001] The invention relates to the technical field of wind power generating set transmission chain monitoring. In particular, it relates to a system and method for evaluating the health state of a transmission chain of a wind turbine. Background technique [0002] At present, with the increasingly serious energy crisis, wind power generation has attracted more and more attention. However, due to the complex structure of wind power generating units and the harsh working environment, various types of failures often occur. The wind turbine gearbox is the core transmission component of the wind turbine, and its working condition will affect the performance of the entire wind turbine. According to statistics, among the three wind turbines, wind turbine gearboxes and wind turbines, the component with the highest failure rate is the wind turbine gearbox, and its failure rate is as high as 40% to 50%. The unit gearbox failure rate is almost 100%. At the same time...
