The invention discloses a compressor adaptive performance curve generation method. The method comprises: obtaining a centrifugal compressor design performance curve and converting the centrifugal compressor design performance curve into a numerical form; obtaining theoretical performance parameters under actual working conditions by utilizing a similarity theory; establishing a performance curve mapping relation according to an ANFIS algorithm, and calculating theoretical performance parameters of all rotating speeds; combining historical operation data of the compressor, introducing a performance curve degradation factor, performing calculating by using a least square method to obtain a value of the degradation factor, and correcting theoretical performance parameters of all rotating speeds through the degradation factor; determining a stable working parameter range of the centrifugal compressor to obtain a compressor surge and blockage boundary curve; and finally generating actual performance curves of all
