The frequency generated by an AC generator is a function of the number of poles in the generator and the speed at which it is rotated.As you can see from the chart almost any frequency can be generated simply by varying the speed of the generator. The formula f=P x S/120 will give the frequency. f=freq, p= number of poles, S= speed of rotation in rpm. Hope this helps understand why a dedicated generating station can deliver any desired frequency. The USA has used 60 cycles almost exclusively, Canada has/had some 50 cycle power plants. If an AC electric motor is connected to any given frequency it will rotate at a speed in relation to the number of poles it has. For more complete information on this subject refer to Information on Electric Locomotives by Steve Sconfienza PhD.
