Abstract: Systems and methods of controlling uninterruptible power supplies of electrical power systems are described. According to one aspect, an electrical power system can include a generator having a stator and a rotor, a power converter coupled to a rotor bus of the rotor, and a control system comprising one or more control devices, the one or more control devices configured to operate the power converter to provide an AC signal for a rotor bus. The system can also include an uninterruptible power supply (UPS). The UPS can include a power storage element configured to receive and store electrical power, and configured to power the control system during a power failure, and, a health check circuit configured to verify a health status of the power storage element, and including a health check disable component configured to disable the health check circuit during the power failure.

Abstract: A wind turbine and associated control method includes a controller configured with a high speed shaft brake in the generator gear train. The controller receives an input signal corresponding to rotational speed of the high speed shaft, wherein upon the high speed shaft reaching a predefined rotational speed and under a braking condition that calls for the rotor to come to a complete standstill, the controller generates an activate signal to activate the brake. An interlock system is in communication with the low speed shaft sensor and the controller and is configured to override the activate signal when the rotational speed of the low speed shaft is above a threshold value.
