Abstract
A system for a wind turbine generator comprising: a set of voltage limiting elements, and a controller configured to bypass the voltage limiting elements when a line voltage is below a predetermined threshold, and configured to connect each voltage limiting element in series between a grid side converter and a turbine transformer of the wind turbine generator, and to determine a current control reference signal for controlling the grid side converter (to generate a determined current) when the line voltage is above the predetermined threshold.
