Control method and device of wind turbine generator, wind turbine generator and remote monitoring system

The invention provides a wind turbine generator control method and device, a wind turbine generator and a remote monitoring system. The control method comprises the steps of obtaining a predicted wind speed of a machine location point where the wind turbine generator is located; in response to the fact that the predicted wind speed of the machine location point in a first preset time period is larger than or equal to a preset wind speed threshold value, a first wind speed identification signal is generated, so that the wind turbine generator set responds to power failure of a power grid in the first preset time period to allow a standby power supply to execute preset load reduction operation, the preset wind speed threshold value represents the preset safe wind speed under the condition that the standby power supply is not used. Standby electricity energy is saved, standby electricity waste is reduced, standby electricity capacity is reduced as much as possible, and cost is saved. 提供一种风电机组的控制方法和装置、风电机组、远程监测系统
