The invention discloses an electric generator frequency modeling method based on practical output characteristics. The method comprises the following steps that: S1: collecting actual measurement data; S2: according to the actual measurement data, drawing a curve graph; S3: dividing the practical output process of an electric generator into a steady state stage, a raising stage, a slipping stage and a climbing stage; and S4: in each stage, constructing a function expression according to a relationship between power and frequency, and finally, overlapping piecewise functions to obtain an electric generator frequency model. By use of the method, the electric generator frequency model based on the practical output characteristics is constructed, a day parting model structure overcomes the deficiencies that an existing model structure is too simple or complex and is inaccurate in setting parameters, and the electric generator frequency model, which gives consideration to simulation degreeand complexity requirements and can accurately reflect frequency big disturbance, based on the practical output characteristics is established.
