Wind power generation control device and system

The invention provides a wind power generation control device and system, and belongs to the field of wind power generation control. The safety chain module is used for receiving the signal to trigger the fan to stop; the pre-monitoring module is used for selecting the working state of starting the monitoring point position, and the wind turbine generator and the impeller are each provided with at least one monitoring point position; the standby monitoring module is used for acquiring working parameters of the monitoring point positions and sending the working parameters to the emergency calculation model; and the trigger module and the emergency calculation model send a trigger signal according to a calculation result so as to start a corresponding fan part on the safety chain module, so that the safety monitoring strength can be adjusted according to different fan types, fault working parameters can be comprehensively and automatically identified, and remote alarm can be performed on the fault part. 本发明提供基于
