Static Frequency & Excitation

We provide state-of-the-art SFC technology for main generators, which often have to be started and run-up at short notice.

GE Vernova is one of the world’s leading manufacturers of SEMIPOL™ SEE units, with an installed base of more than 1,000 systems in the field.

The static excitation system provides the necessary field current for synchronous generators from 20 MW to 1,000 MW.
