Wind power generation system, early warning method of wind turbine generator of wind power generation system and readable storage medium

The invention discloses a wind power generation system, a wind turbine generator early warning method and a readable storage medium, and the method comprises the steps: obtaining a rotating speed value and a power value in an abnormal time period when a power curve of a generator of a wind turbine generator in the wind power generation system is monitored to be abnormal based on a preset detection model, the wind speed value is collected by an anemograph of a wind turbine generator system where the generator is located in the abnormal time period; generating a wind power curve comparison graph by using the wind speed value and the power value, and generating a scatter point comparison graph by using the rotating speed value and the power value; according to the wind power curve comparison graph and the scatter point comparison graph, determining a risk value and a reference maintenance measure of the generator; and generating early warning information according to the obtained historical early warning informa
