WebOne of the most common ways of changing the output frequency of a generator is to change the rotation speed of the engine. The two factors are related as per the following formula – Generator Frequency (f) = Number of revolutions per minute of the engine (N) * Number of magnetic poles (P) / 120 Conversely, P = 120*f/N WebControlled case: If frequency of two areas is to be controlled, the static frequency drop is just one half of that of the isolated operation of two systems If there is change in load in any area, half of it will be shared by the other area. It is found that if a load changes in an area, the frequency and
