ADAPT.wind Condition Monitoring Solution
A Smarter Way to Operate Your Wind Farm.
Our Advanced Distributed Architecture Platform Technology incorporates more than 50 years of condition monitoring expertise, integrating Bently Nevada instrumentation, reliable up-tower continuous signal processing, and software for trending, analysis and diagnostics. It proactively detects drivetrain issues so you can plan and optimize maintenance outages. Your potential benefits include increased availability, improved reliability, and lower crane costs. The ADAPT.wind solution is the standard for condition monitoring on GE’s wind turbine units and is readily deployable on other manufacturers’ equipment.

Why Monitor?Why Monitor?Wind turbine monitoring is needed because turbines often face unpredictable conditions that can negatively impact operation. Advanced condition monitoring techniques and experience are critical to reliably managing your assets.
The Gearbox Is Priority #1Planetary/helical gearbox failure is a primary concern for manufacturers and operators. As much as 25%–30% of wind farm operating and maintenance costs are associated with the gearbox alone. A Bently Nevada integrated condition monitoring system enables operators to understand the gearbox condition remotely. Dependable knowledge of the gearbox condition enables continued operation and revenue generation when a defect is not significant, while mitigating the risk of run to failure, an unplanned outage or catastrophic event.
Proactive condition monitoring across your fleet also helps operators plan efficiently for and coordinate maintenance outages. Consolidating maintenance into one outage, and scheduling one crane, can save hundreds of thousands of dollars.
Benefits
SoftwareUnderstanding Unit OperationsReliable continuous condition monitoring for the gearbox, generator, main bearing, and tower sway enables you to understand issues weeks, or even months in advance.
Domain KnowledgeWe’ve embedded more than 50 years of Bently Nevada condition monitoring expertise into this solution, gained from having more than two million permanently installed transducers and monitoring channels—the largest installed base in the world. And the ADAPT.wind solution incorporates the intelligence of System 1 software, GE’s industry-leading optimization and diagnostic software platform. By transforming data into knowledge, owners and operators alike can make informed decisions with confidence.
Network-Friendly and ScalableThe powerful up-tower processor contains all configurations and algorithms with inputs from accelerometers on the main bearing, gearbox, and generator; and from the integrated turbine control system. The ADAPT.wind software can also be integrated with SCADA systems while minimizing congestion on the SCADA network.
This solution is equally applicable for one or many wind farms. An entire wind farm can be monitored locally from the wind farm Advanced Technology that Solves Gearbox ComplexitiesOur patented Planetary Cumulative Impulse Detection algorithm is a set of measurements that detect and trend the passage of debris particles through the planetary stage of a wind turbine gearbox. This provides greater insight into gearbox condition and helps pinpoint problem areas. The Dynamic Energy Index (DEI) algorithm is specifically designed for variable speed machines. DEI spreads the variation over five bands of operation for more accurate spectral energy calculations and earlier fault detection.
