Posters
Come meet the poster presenters to ask them questions and discuss their work
We would like to invite you to come and see the posters at our upcoming conference. The posters will showcase a diverse range of research topics, and will give delegates an opportunity to engage with the authors and learn more about their work. Whether you are a seasoned researcher or simply curious about the latest developments in your field, we believe that the posters will offer something of interest to everyone. So please join us at the conference and take advantage of this opportunity to learn and engage with your peers in industry and the academic community.
On 9 April at 17:15, we’ll also hold the main poster session and distinguish the 7 best posters of this year’s edition with our traditional Poster Awards Ceremony. Join us at the poster area to cheer and meet the laureates, and enjoy some drinks with all poster presenters!
We look forward to seeing you there!
PO208: CMS support in preventive maintenance actions to extend the useful life of direct drive turbine main bearings
Emerson Lima, Head of Condition Analysis Center (CAC), Aqtech
Abstract
Direct drive wind turbines represent a significant portion of wind generation. These turbines eliminate the need for a gearbox by connecting the main rotor directly to the generator, reducing the number of mechanical components subject to failure, and resulting in less maintenance and downtime. This type of turbine allows for an efficiency 5% higher than that of gearbox driven turbines. To operate at low rotation speeds, direct drive turbine generators tend to be larger and heavier, which results in higher costs when compared to gearbox driven turbine generators of the same capacity. In the event of a failure that requires the replacement of a large component, the costs in a direct drive turbine are higher than the costs of this same component in a gearbox driven turbine. To minimize excessive costs with the replacement of large components, condition monitoring systems (CMS) are commonly used. Among their functionalities, the following stand out: * Ability to identify defects early, allowing for better planning of corrective actions. * Ability to identify operating conditions that reduce operational risk, even when a defect is present. * Perform correlations with maintenance actions to assess the conservation of the asset's useful life.
