Generator Exciter Controls

Digital Excitation Systems

Our Ovation excitation systems are suitable for a wide range of synchronous generators and exciters driven by virtually any type of prime mover and also for synchronous motors used in pumped storage facilities.

Leveraging our decades of experience in the power generation industry, we have created a reliable platform on which to operate our sophisticated and flexible software. The excitation system provides all of the features required for precise control and protection of the synchronous machine under normal and fault conditions.

In most applications, the system is backed up by an emergency manual control subsystem which provides an additional level of reliability such that a loss of the excitation system computers will not result in a loss of excitation.
