The invention discloses a generator speed regulation method and device and a storage medium, and belongs to the technical field of vehicle control. The method comprises the steps that the first torque of an engine is calculated based on the current allowable generated power of a power battery and the rotating speed of the engine, and the first torque is the torque needing to be provided by the engine when the current allowable maximum generated power of the power battery is reached; determining an engine torque deviation based on the first torque; calculating the torque upper limit of the engine based on the engine torque deviation, the maximum negative torque allowed by the generator, the rotating speed of the generator and the rotating speed of the engine; the second torque of the engine is inversely calculated based on the whole vehicle consumed power, the discharging power of the power battery and the rotating speed of the generator; in response to the second torque being greater than the upper torque limit of the engine, the governed power of the generator is released based on the second torque and the upper torque limit of the engine. Accuracy of generator speed regulation is guaranteed, and safety of a vehicle power supply system is guaranteed.
