GENERATOR
Governor- : Governor is a speed control system ,that acts on the turbine ,adjusting the inlet valves for the turbine.This is used to adjust the real power o/p from the generator or to regulate the frequency .Operation can adjust it's preset position for a direct change of real power o/p. Exciter -: Exciter is the unit that establishes DC current in the field winding . AVR -: AVR is a closed loop controller that fields control input of the exciter . Real Power Control -: Real power produced by the generator is approximately equal to the mechanical power received by the generator . Governor is an inlet valve control mechanism activated through the opeartor . Real power o/p from a generator only be changed by adjusting the governor preset position. Reactive power control -: E - induced EMF phase voltage Q- Reactive power According to the expression of Q , we controll Q by adjusting induced emf E ,by adjusting induced emf E ,by adjusting excitation dc current (i) Increase (i) to incre...
