Method and terminal for calculating output of multiple offshore wind plant groups under influence of typhoon

The invention discloses an output calculation method and terminal for multiple offshore wind plant groups under the influence of typhoons, and the method comprises the steps: carrying out the training of the obtained historical typhoon trajectory data, thereby predicting the typhoon trajectory range, and simulating the uncertainty of the typhoon trajectory in this way; according to the predicted typhoon trajectory range, a wind speed scene around the typhoon trajectory range is obtained by adopting a vortex wind field model, a wind speed-fan output physical model is established by combining the wind speed scene of the wind power plant, environmental parameters and fan parameters, and then output scenes corresponding to a plurality of wind power plants are calculated according to the wind speed-fan output physical model. In this way, under the condition that typhoon disasters occur in the working environment of multiple wind power plants on the sea, the change of wind power output prediction caused by the unce
