Method for conveniently drawing characteristic curve of generator

The invention relates to a method for conveniently drawing a characteristic curve of a generator. The method is characterized by comprising the following steps of: firstly, inputting parameter values of eleven parameters; secondly, drawing a no-load saturation characteristic curve which comprises an air-gap line, a short-circuit curve, a no-load curve and a zero-power factor curve; thirdly, drawing a VEE curve; and finally, drawing an output curve. According to the method provided by the invention, the characteristic curve can be drawn by inputting the eleven parameters, and a requirement for correction of the characteristic curve of each project can be well met.
