The invention belongs to the technical field of wind power information monitoring, and particularly relates to a visual monitoring method, a device and a system based on the CFD flow field analysis. The method comprises the following steps of acquiring the operation information and the equipment information of each wind mill in a wind power plant, wherein the operation information comprises the wind speed information, and the equipment information comprises the mounting position information, the height information and the wind mill model information; acquiring the visual CFD flow field information corresponding to the wind speed information from a visual CFD flow field database based on the wind speed information and displaying the visual CFD flow field information in real time, wherein the visual CFD flow field information comprises the visual flow line information around each wind mill and the blade thereof. According to the invention, the visual display of the CFD flow field information and the structural stress information of each wind mill in the wind power plant is realized. Therefore, the safe operation condition of wind mill equipment can be displayed more visually, so that the fault analysis, the monitoring and analyzing for the insufficient generating capacity and the vibration fault analysis of the wind mill are facilitated for the monitoring personnel. The monitoring efficiency of the operation personnel is improved.
