[0003] However, wind turbines are generally installed in locations with relatively harsh environments (for example, installed in the sea). Therefore, when a component in the wind turbine fails and the wind turbine is shut down, it is difficult for maintenance personnel to reach the location of the wind turbine in time. The installation site went to repair the fault, which caused the wind turbine to be shut down for a long time
The long-term shutdown of wind turbines will cause great losses to users.
[0004] Therefore, the fault handling method of the converter in the above-mentioned wind power generating set will cause great losses to the user

The invention provides a fault processing method and a fault processing device for a converter of a wind power generating set. The fault handling method includes: detecting whether a fault occurs in the converter; when at least one fault is detected in the converter, determining the fault level corresponding to each fault in the at least one fault; determining all the determined faults The highest failure level in the levels; execute the failure handling corresponding to the highest failure level. By adopting the fault handling method and the fault handling device of the converter of the wind power generating set in the exemplary embodiment of the present invention, different fault handling can be performed by determining the different levels of the fault of the converter, so that the wind power generating set can be avoided due to Losses caused by frequent downtime due to failures.
Description
technical field [0001] The present invention relates to a fault processing method and device, more specifically, to a fault processing method and fault processing device for a converter of a wind power generating set. Background technique [0002] For the important components in the wind power generating set, once a failure occurs, the wind generating set is usually shut down directly for reasons of safety and the like. For example, when the converter in the wind turbine fails, the wind turbine will stop directly. At this time, the circuit breaker in the wind turbine will also be disconnected. After maintenance personnel repair and restart the wind turbine, the wind power The generator set will run normally and enter the power generation state. [0003] However, wind turbines are generally installed in locations with relatively harsh environments (for example, installed in the sea). Therefore, when a component in the wind turbine fails and the wind turbine is shut down, it ...
