Rigorous quality assurance, right from the start The Vestas Test Centre is unrivalled in the wind industry and has the unique ability to test complete nacelles using Highly Accelerated Life Testing (HALT) to ensure reliability. At the critical component level, potential failure modes and mechanisms are identified, and rigorous design verification plans and procedures for testing and verification are made. Specialised test rigs are then used to ensure strength and robustness for the gearbox, generator, yaw and pitch system, lubrication system and accumulators. The Vestas quality-control system ensures that each component is produced to validated design specifications, and performs at site. We also employ a Six Sigma philosophy and aim to perform at Six Sigma levels by 2011. We have identified the critical manufacturing processes (both in-house and for sub-suppliers), and we systematically monitor measurement trends that are critical to quality, to identify variation and make changes before any defects occur.2011-01-05T13:49:14+01:00http://nozebra.ipapercms.dk/Vestas/Communication/Productbrochure/V11230MW/V11230MWOffshoreUK/?Page=12http://nozebra.ipapercms.dk/Vestas/Communication/Productbrochure/V11230MW/V11230MWOffshoreUK/?Page=12Uninterrupted control of wind energy production, at your service VestasOnline® Business Vestas wind turbines benefit from the latest Supervisory Control and Data Acquisition (SCADA) system for modern wind power plants: VestasOnline® Business. This flexible system includes an extensive range of monitoring and management functions that allow you to control your wind power plant in the same way as a conventional power plant. VestasOnline® Business enables you to optimise production levels, monitor performance and produce detailed, tailored reports from anywhere in the world while the system’s power plant controller provides active and reactive power regulation, power ramping and voltage control. Surveillance, maintenance and service Vestas provides 24/7 monitoring, performance reporting and predictive maintenance systems to improve turbine uptime, production and availability. Operating a large wind power plant today calls for highly efficient management strategies, to ensure that power production is uninterrupted and that operational and maintenance expenses are controlled. The ability to predict when your critical components are most likely to break down is essential to this effort, as it helps to avoid costly emergency repairs and unscheduled interruptions to energy production. The Vestas Condition Monitoring System performs this predictive maintenance function, assessing the status of the V112-3.0 MW Offshore by analysing measured signals such as vibrations and temperatures (e.g. in gearbox bearings and the main bearings). For example, by measuring the vibration of the drive train, the system can detect faults at an early stage and monitor the progress of the damage. This information allows the service organisation to plan and execute the required maintenance work before the component fails, reducing repair costs and production loss. What’s more, our Active Output Management® (AOM) concept provides detailed plans for service and maintenance, online monitoring, optimisation and troubleshooting, and includes a competitive insurance scheme. It is even possible to get a full availability guarantee, under which Vestas pays compensation if the turbine fails to meet the agreed availability targets. For every offshore wind project, we provide a service solution fully customised to meet the site’s specific requirements. Thanks to our superior operations and maintenance capabilities, we also provide a level of service unparalled in the industry.2011-01-05T13:49:14+01:00http://nozebra.ipapercms.dk/Vestas/Communication/Productbrochure/V11230MW/V11230MWOffshoreUK/?Page=13http://nozebra.ipapercms.dk/Vestas/Communication/Productbrochure/V11230MW/V11230MWOffshoreUK/?Page=13VestasOnline® This SCADA system turns a group of wind turbines into a wind power plant main Grid Grid meter VestasOnline® SCADA Server VestasOnline® Power Plant Controller mSC mSR STATCOm Let our experience guide you We have pioneered the offshore wind industry and installed around half the world’s offshore wind turbines.
