 Wei QiaoAbstract- This webinar will present the pioneering work conducted by the Power and Energy System Laboratory at the University of Nebraska-Lincoln, Lincoln, NE, USA on low-cost, online, prognostic condition monitoring (PCM) for wind turbines and their mechanical and electrical subassemblies, such as gearbox, bearing, blade, drivetrain, and generator. The PCM methods primarily use current signals acquired from generator terminals or in the power electronic converter control system to online diagnose and prognose the faults and predict the RUL of the wind turbines in all operating conditions. In addition to current signals, the PCM can also be used to include vibration signals in wind turbines to provide additional PCM capability and improved diagnosis and prognosis accuracy. The PCM methods developed have been successfully applied for fault diagnosis and prognosis and RUL prediction of wind turbines of different types and different sizes from kW to MW scale in both the laboratory and field. The PCM methods developed outperformed the state-of-the-art wind turbine condition monitoring technologies in terms of cost, hardware complexity, implementation, accuracy, capability, and reliability. They provide a low-cost, reliable solution for the wind industry to reduce the failure rate and level, O&M costs, and downtime, improve reliability, and extend the life of wind turbines.

PELS/IAS Joint webinar: Powering the next decade by reviewing the past


Stephanie ButlerPresenter: Dr. Stephanie Watts Butler
Technology Innovation Architect, Texas Instruments
The IEEE Energy Conversion Congress and Exposition (ECCE) recently celebrated its tenth anniversary – a decade that coincided with an unprecedented shift in technology for power generation, delivery, and conversion. This shift, coupled with the advent of smart phones and IOT, has enabled an explosive growth in electronification in industrial, consumer, and automotive markets. According to IC Insights, power management ICs ship in greater quantity than any other type of IC device. The resulting broad application corresponds with an impressive expansion in the features and capabilities of power semiconductors to address the vast scope of end equipment needs. This presentation will examine the changes in power management semiconductors over the past decade. Integration, system in package, voltage levels, and process technologies will be discussed. How different features are necessary for different markets and applications will be considered. The webinar will conclude with an examination of this year’s Applied Power Electronics Conference (APEC), demonstrating the continued expansion of semiconductor capabilities and applications

 DusmezAbstract: As the industry moves towards “smart factory” and next level of automation, the demand for miniaturization of manufacturing equipment to save floor space and reduce the time required to install and commission equipment is becoming more critical.  This presentation discusses how GaN is enabling the next generation of highly efficient integrated motor drives. These solutions result in >75% reduction factory floor cabinets while reducing power and communication cabling by more than 90%. An actual design example will be shown and discussed.

 Bio: Dr. Serkan Dusmez is the Systems Engineer of the GaN Product Line at Texas Instruments (TI) responsible for the product and roadmap definition of GaN products and the development of high-frequency power converters. He has worked on various areas of power electronics including new topologies and control algorithms for next-generation power converters. He is the author/coauthor of over 60 IEEE papers. Dr. Dusmez graduated with a PhD from the University of Texas at Dallas.
