Automatic vortex-induced-resisting method and system for wind turbine generator and storage medium

The invention provides an automatic anti-vortex-induced method and system for a wind turbine generator and a storage medium, which are applied to wind turbine generator control and comprise the steps that when a power grid is normal and the generator set triggers any shutdown condition, a variable pitch system is powered by the power grid to retract three blades to a pressure limit switch, and then the three blades are turned on; the main control judges that an anti-vortex-excitation instruction is issued to a shaft with the highest backup power supply voltage in the current variable-pitch system, and the variable-pitch system enters the anti-vortex-excitation mode; when the power grid is powered down, the unit triggers emergency shutdown, after the variable pitch system is powered by the backup power supply and the three blades are retracted to the pressure limit switch, the master control judges that an anti-vortex-excitation instruction is issued to the shaft with the highest backup power supply voltage in
