Webis internal to the generator is used to compensate the voltage drop on the step up transformers [4], [2]. Under excitation limiter (UEL) is used to prevent generator excitation from dropping to the limit at which generator stability is lost. The limiter input signal is either generator voltage and current, or active and reactive power. The limits WebFor SG, equation is “Mechanical Input = Electrical output (Active power) + losses”. As written above, if SG is running at high excitation than it may generate reactive power, i.e. SG will supply the reactive power to the system. In fact, what’s happen, it is just an energy exchange between generator & load.
