why the excitation is necessary to produce the reactive power
Answer Posted / lokesh raj
AN EXCITED OR OVER EXCITED GENERATOR PRODCUES COMPARETIVELY
HIGHER VOLTAGE AND HIGHER CURRENT, BUT FOR CONSTANT LOAD
V*I*Cos(angle) IS CONSTANT. AS VOLTAGE AND CURRENT IS
INCREASED V*I*Sin(ANGLE) THAT IS REACTIVE POWER.
AS THE EXCITATION INCREASED THE REACTIVE POWER INCREAED.
