Wind Turbine Generator Repairs
With wind turbines located in typically remote locations and with the associated difficulty in removing and replacing generators, the need for the highest possible level of quality and reliability during the wind turbine generator repair process is essential.
At RJW we recognise the importance of this and have invested in the very latest repair and test equipment to ensure that every aspect of the generator is inspected and tested during the wind turbine generator repair process with the sole purpose of minimising the chance of unexpected failure.
In addition to the investment in facilities and training we have developed our own dedicated wind turbine generator repair procedure specifically for this type of unit in order to prove reliability and quality of repair enabling trouble installation and use once the generators return to site.
During the wind turbine generator repair process, as well as detailed component inspections, the condition of the winding and core of both the rotor and stator are tested recorded using the best winding and core loss equipment available. This is backed up with thermographic analysis of the rotor and stator core to ensure a lack of hotspots within the core that could compromise efficiency and reduce the service life of the generator.
All stators and rotors that are rewound as part of the wind turbine generator repair are vacuum pressure impregnated to improve the repair life of the generator.
With dynamic test facilities for generators up to 3MW and comprehensive static test equipment we are able to guarantee the future performance of the generators. The specially developed test rig has been built to dynamically test generators following repair, enabling the measurement of electrical and mechanical performance prior to installation, recording stator and rotor winding conformity as well as vibration data under a variety of running conditions.
All aspects of the wind turbine generator repair are recorded on the RJW ‘Wind Portal’ enabling password controlled online access for customers on a 24/7 basis, giving up to date information including scheduled delivery date, current repair progress, test records and photographs of generator damage/wear.
