Abstract

In this paper, the voltage sag ride-through capabilities of the line-connected electrically excited synchronous motors with damper windings (EESMs) is investigated. Two aspects are investigated, first the capability to keep the nominal speed and second the damping of speed oscillations by controlling the flux. We will design a voltage sag ride-through controller and show through simulations that the proposed controller has good speed oscillation damping capability and that the ride-through capability is improved.
