Improved Voltage Sag Ride-Through for Line-Connected Synchronous Machines
نویسندگان
چکیده
In this paper, the voltage sag ride-through capabilities of the line-connected electrically excited synchronous machine with damper windings (EESM) is investigated. We will design an algorithm for voltage sag ride through by controlling the flux. Two aspects are investigated, first the capability to keep the nominal speed and second the damping of speed oscillations. We will show through simulations that the proposed algorithm has good speed oscillation damping capability and that the ride-through capability is improved.
