LogiLube and Flender Corporation have signed an agreement to collaborate in testing the SmartGear condition monitoring technology platform on a Winergy gearbox for a GE 1.5 MW wind turbine. The proof of concept tests are taking place at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) in Golden, Colo., U.S.A. where Winergy has installed a gearbox specifically instrumented with measurement equipment to evaluate advanced drivetrain technologies under a 12-month Cooperative Research and Development Agreement (CRADA).

Comprised of Internet of Things (IoT) enabled sensors, real-time oil condition monitoring, oil sampling and analysis, edge computing and data analytics, as well as cyber-security features, “SmartGear is an advanced sensor suite that will provide the team critical information about the operating environment of the gearbox lubricant,” says Jon Keller, CRADA project leader.

Under real operational conditions, the test will validate SmartGear platform’s capability to provide in-line, real-time oil condition monitoring for wind turbine systems. The automated in-service oil sample collection process is coupled with LogiLube’s SmartLab mobile application comprising a full suite of tracking and reporting tools.

Winergy and LogiLube expect that the central processing of dozens of parameters by the onboard mounted edge-processor will allow real-time analysis and reporting without interrupting run-time of the turbine. Particle count and size, water contamination, oil viscosity and the presence of aerated (foamed) oil are but a few of the critical parameters monitored in real-time by the SmartGear system.

Proprietary algorithms are edge processed and the results are transmitted wirelessly every 30 seconds to a secure client accessible web-based dashboard, providing actionable intelligence.

Gearbox lube oil samples are autonomously collected while the turbine is in full operating mode and are tracked and protected with end-to-end chain-of-custody providing a data log from “edge-to-lab-to-cloud.”

LogiLube’s SmartLab smartphone app ensures the physical oil sample is matched with raw wind turbine operational data that is uncorrupted, thereby lowering the risk of human error and providing unparalleled data integrity.

SmartGear has the ability to monitor fluid samples for particles (ferrous and non-ferrous) of as small as 4 microns, which is approximately one-tenth that of conventional wind industry oil monitoring solutions today. Twenty times smaller than the diameter of a human hair, detection of 4-micron particles gives wind turbine operators the ability to monitor wear particle behavior in real time.

Coupling the real-time capability of SmartGear with the physical oil sample analysis of SmartLab will provide the corroborating evidence to support a data-driven O&M response.

“Having access to the data provided by this technology will significantly increase availability. The method of measuring continuously key oil condition parameters and verifying them through oil samples is unique in the industry,” says Edwin Hidding, head of Digital Gearbox at Winergy.

Throughout the 12-month CRADA, NREL researchers will climb the tower of the GE 1.5 MW wind turbine to collect the used oil sample bottles every two weeks. The resulting oil analysis reports will be coupled with 100 million data points of real-time gearbox operational and oil quality data reported by the SmartOil™ system every 30 seconds and accessible via a secure web dashboard.

Additionally, LogiLube will be using their SmartData platform and remote app servers to analyze the real-time data from the NREL test. The calibration and preliminary testing on the Winergy gearbox appear to indicate that the operational intelligence developed by the SmartGear platform is capable of providing actionable insight to make informed predictive maintenance decisions.

“Asset owners, gearbox manufacturers and wind turbine OEMs have already provided us feedback that the use of fleet-wide operations and performance data to spot condition-based changes which signify potential component failures is a key element to their successful operations,” says Bill Gillette, LogiLube founder and CEO.
