More Information
Summary:WIND PITCH ADJUSTMENT SYSTEM Systems and methods for controlling a wind pitch adjustment system associated with a wind turbine system are disclosed. In one embodiment, the wind pitch adjustment system can include a power supply configured to convert an alternating current input signal into a direct current voltage, a controller configured to receive a signal from the power supply, and to provide one or more control commands to a pitch adjustment motor, and a surge stopping device comprising a switching element coupled between the power supply and the controller. The surge stopping device is configured to monitor an input voltage from a grid and to drive the switching element based at least in part on the monitored input voltage, such that the switching element is configured to block current flow through the switching element to the controller when the monitored input voltage is above a voltage threshold.
