Abstract: The present subject matter is directed to systems and methods for controlling variable speed generators, particularly converters associated with doubly-fed induction generators (DFIG) to permit use of harmonic attenuating filters that are generally smaller and less costly than previous similar filters. The subject matter provides for controlling line-side and rotor-side converters in such a manner that the frequencies generated by the converters are interleaved in a manner that the filters see a higher switching frequency and thus may be designed based on those higher frequencies, thereby requiring smaller and less expensive components.

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.

Abstract: A role-based access control method and/or system permits end users to securely pair their mobile devices via a pairing apparatus with one or more instruments to, for example, remotely monitor operations of the instruments. In an embodiment, the process includes a pairing apparatus receiving a pairing request from an instrument including a unique access code, and receiving a pairing request from an end user mobile device that includes an end user mobile device identifier and an access code. If the unique access code matches the end user's access code, then the end user mobile device identifier is added to a security group and a successful pairing message is transmitted to at least one of the instrument and the end user mobile device.

Abstract: The present subject matter is directed to systems and methods for improving reliability of dual bridge doubly fed induction generators (DFIGs) by reducing the number of required components in the converters associated with such DFIGs. A converter is constructed using a pair of current conducting bridges wherein one of the current conducting bridges is controlled and the second is not controlled. The uncontrolled bridge may correspond to a pair of diodes while the controlled bridge may correspond to a pair of transistors, in particular, a pair of IGBT transistors.
