Abstract
Systems and methods for controlling reactive current output of a line converter in a power system are provided. In one example embodiment, a method includes receiving a margin signal determined based at least in part on a stator current margin or a rotor current margin. The method includes determining a spillover margin based at least in part on the margin signal. The method includes determining an adjusted spillover margin using a spillover gain. The method includes determining a reactive current command for a line converter based at least in part on the adjusted spillover margin. The method includes controlling the output of the reactive current by the line converter based at least in part on the reactive current command. The spillover gain is variable based at least in part on a maximum line converter current.
