The invention relates to the technical field of wind power generation, and discloses a method and device for fast starting a wind generating set and a computer readable storage medium. The method forfast starting the wind generating set comprises the following steps that pneumatic data of a wind turbine blade is acquired, and a pneumatic model curve family of the wind generating set is obtained according to the pneumatic data; based on the pneumatic model curve family, a pitch angle control curve of the wind generating set started with the maximum torque is obtained; and the pitch angle control curve is corrected, an optimal pitch angle control curve is obtained, and the wind generating set is controlled to be started based on the optimal pitch angle control curve. Therefore, when the wind generating set is started, the pitch angle is dynamically adjusted, so that the wind turbine blade obtains the maximum starting torque, and the starting time of the wind generating set is shortened;and the problem that due to the fact that the wind generating set is started with a fixed pitch angle, and consequently the starting time is long is effectively avoided, and therefore the operation efficiency of the wind generating set is improved.
