The excitation and excitation systems have a great effect on the dynamic performance of the generator. Generator voltage and quality of reactive power, in short all electric
The quality of the energy distributed to its users is determined by the excitation and excitation systems.
Different excitation systems are available:
Brushless excitation systemsSwitch excitation machine and automatic voltage regulator (AVR) Static excitation systems (SES) supplying the rotor directly via the brushes to the thyristor bridge
To ensure stable operation, to communicate with power plant control system and to operate within the working limits of the generator.
ABB's UNITROL series rotary excitation and static excitation for the control of all kinds of synchronous machines (motors and generators)
microprocessor based voltage regulators.
  UNITROL® includes automatic voltage regulators (AVR) and static excitation systems (SES) that can be used for synchronous generators and motors of all sizes.
