The brushless designed synchronous generators are equipped with digital excitation system to comply with stringent requirements on voltage variation of ±10%, voltage regulation of ≤0.25%, voltage imbalance, reactive power and power factor control. Permanent Magnet Generators can be offered for the purpose of pilot generation to improve voltage waveform, reduce voltage distortion, positive voltage built up, ability to sustain short circuit current in the event of fault, less voltage imbalance etc.
