Electrical Power Pdf, Automatic Voltage Regulator corrects the excitation to ensure in the machine design power variable, the voltage is right whatever the present. If it corrects the excitation to provide the right voltage in other power variables, then two machines won’t operate in parallel. An individual can provide a huge leading present and another a massive lagging present. A”droop” is required to provide a lesser voltage in the event the energy factor dissipates by greater than the machine layout. This is reached from the compounding. Faulty Compounding causes shaky consumption of kVAr that may be very violent.
System Faults. When an error occurs, originally de currents are induced from the damping twisting and primary field circuit contrary to the demagnetizing effect of this very low energy variable fau lt present. These currents perish away resulting in the error current to collapse. In extreme cases it could drop beneath the complete load value.
