The invention discloses an electric energy meter fault-tolerant operation control method for a wind turbine generator, which is based on the characteristics of a multi-electric energy meter wind turbine generator, adopts a fault time fault-tolerant mechanism, expands the fault robustness to system-level robustness fault tolerance, and realizes that the wind turbine generator can still perform fault-tolerant unlimited power operation under the condition that a single electric energy meter is abnormal. Therefore, fault shutdown is avoided. Aiming at a multi-winding parallel wind turbine generator with an independent grid-side circuit breaker arranged on the grid-connected side of a winding at present, the single-winding operation function of the converter is utilized to realize that under the condition that a certain winding electric energy meter is abnormal, even if the fault-tolerant operation of the wind turbine generator exceeds the maximum fault-tolerant time, the wind turbine generator ...
