The invention relates to the technical field of wind turbine generators, and discloses a method and device for correcting low-voltage ride-through characteristic model parameters of a wind turbine generator and a storage medium. The method comprises the steps of determining a first control parameter of the wind turbine generator after a voltage drop fault occurs and a first control mode for the first control parameter; establishing an initial model of the low-voltage ride-through characteristic of the wind turbine generator according to the first control parameter and the first control mode; acquiring working parameters of the wind turbine generator during the voltage drop fault, and determining a corresponding second control parameter and a second control mode for the second control parameter according to the working parameters; correcting the first control parameter and the first control mode according to the second control parameter and the second control mode to obtain a final model of the low-voltage rid
