New energy power generation system online frequency modulation method based on wind power generation

The invention discloses a new energy power generation system on-line frequency modulation method based on wind power generation, a wind power generator is provided with a frequency control system, and the method comprises the following steps: constructing a control model comprising a fuzzy controller, and establishing a fuzzy rule of the fuzzy controller; the power grid frequency offset of the new energy power generation system and the current wind direction angle wind speed variation in the first time interval are obtained and serve as control model input data for fuzzy reasoning; outputting fuzzy frequency control output; defuzzifying the fuzzy frequency control output to obtain a control value of the control model; and adjusting the output frequency of the wind driven generator by controlling the model to a frequency control system. The fan frequency adjustment is corrected according to the wind speed variation of the current wind direction angle within the first time interval from the current moment, and
