Abstract
Systems and methods for determining current limits used in controlling wind turbine systems are provided. An example wind turbine controller identifies a largest current magnitude out of a first current magnitude, a second current magnitude, and a third current magnitude of a three phase power bus. The turbine controller averages the first current magnitude, the second current magnitude, and the third current magnitude to obtain an average current magnitude. The turbine controller determines a maximum current adjustment factor based at least in part on the largest current magnitude and based at least in part on the average current magnitude. The turbine controller adjusts a maximum current magnitude limit of the wind turbine by the maximum current adjustment factor to obtain an adjusted maximum current magnitude limit. The turbine controller controls the wind turbine based at least in part on the adjusted maximum current magnitude limit.
