Fault handling method and apparatus for wind power generator set, and computer readable storage medium

A fault processing device for a wind turbine, the fault processing device comprising:

• a grouping module, configured to group faults of the wind turbine based on a target protection object, wherein the target protection object comprises a rotational speed or an insulated gate bipolar transistor (IGBT) temperature of a converter of the wind turbine, and each group of faults comprise a plurality of process faults associated with the target protection object and a target fault of the target protection object, wherein the target fault is an abnormal condition in which the target protection object exceeds a protection domain degree, and each of the plurality of process faults is an abnormal condition that is capable of causing the target protection object to exceed the protection domain degree;
• a fault tolerance module, configured to perform a fault-tolerant control on the wind turbine, in a case that any one of the plurality of process faults in the same group as the target fault reaches a corresponding process fault trigger condition and the target fault does not reach a corresponding target fault trigger condition;
• and
• an identification module, configured to select, in a case that the target fault reaches the corresponding target fault trigger condition, a process fault with the highest degree of correlation from triggered process faults in the same group as the target fault, as a real fault resulting in shutdown of the wind turbine.
