![]() ![]() The R&D activities on operational reliability improvements covered include benchmarking, performance and condition monitoring, and predictions on the remaining useful life of components. Some inherent reliability challenges covered include gearbox planetary stage loads investigation, high speed shaft and main bearing operational more » condition understanding, dynamic modeling approaches, and recommended practices. It covers two angles of reliability, inherent and operational, and goes into detail on specific R&D activities. Department of Energy's National Renewable Energy Laboratory (NREL) over the last ten years. This presentation discusses a few research and development (R&D) activities on drivetrain reliability carried out by the U.S. There are, however, opportunities to understand drivetrain reliability challenges and investigate potential mitigation solutions. = ,ĭespite reliability improvements made to wind turbine drivetrains over the years, premature component failures are still challenging the wind industry. In addition, we have identified several R&D opportunities that can be picked up by the research community to help industry advance in related areas, making wind power more cost competitive in the future. They reflect the expected evolution of wind turbine condition monitoring and O&M in the US market-primarily, a land-based perspective. Most of the work discussed has been published and can be referred to for more information. A high-level summary of these more » activities is provided in this paper along with some key observations from each activity. These activities included technology evaluation during the first few years novel monitoring technique investigation (specifically, compact filter analysis) during the middle years and data and physics domain modeling for fault detection and prediction in recent years. The wind turbine drivetrain condition monitoring and wind plant O&M research that is the subject of this paper is part of the NREL initiative and includes a few research and development (R&D) activities conducted during the 2010s. As early as 2007, the US Department of Energy (DOE) started to address this challenge through the National Renewable Energy Laboratory’s (NREL’s) reliability initiative that first focused on gearboxes and more recently expanded to entire drivetrains. The problem of premature component failure is industry wide. ![]() Among various turbine components, gearboxes-and, more broadly, drivetrains-have shown to be costly to maintain throughout the design life of a wind turbine. Despite performance and reliability improvements of utility-scale wind turbines over the years, the industry still experiences premature component failures, leading to increased operation and maintenance (O&M) costs. The wind industry has seen tremendous growth during the past two decades, with the global cumulative installation capacity reaching more than 650 gigawatts by the end of 2019.
