The excitation system sits right at the core of any power generation plant. It is in fact in charge of producing the direct current that generates the magnetic field that, which controls the machine terminal voltage, thus reactive power to the network. Fast and dynamic control of the magnetic field enables stable control even in case of severe network faults.
ABB is the world leading supplier of high-quality indirect (brushless) and static excitation systems, synchronizing equipment as well as consultancy packages like simulation and grid code compliance studies.
ABB's solutions for excitation are part of a comprehensive suite of automation, electrical, rotating machine control, motors and generators that combine 125+ years of engineering experience and thousands of installations around the world.
