Wind generation has been a part of the US electricity supply since the early 1980’s and since that time, the contribution of wind power has continued to increase, currently accounting for approximately 6% of the total electricity produced. Although wind generators have been in-service for over 40 years, the generators, of all types, are notorious for issues of reliability. EME excels at diagnosing the root cause of equipment failures and engineering repairs to address which can be implemented in-situ, saving the significant cost associated with having to bring in a crane to remove the generator from service. What can EME do for Wind owners and operators? – Develop creative and cost effective solutions to improve the capacity factor of your fleet or farm.

As in all of the segments of our practice, EME prides ourselves on developing cost effective and practical solutions to rotating equipment issues. As expert machine designers, we are uniquely capable of understanding in detail the design of any machine, and formulating corrective actions to address any deficiencies that may exist.

For the case presented here, a thermal ventilation study was performed and a modification to the ventilation circuit developed which would decrease the both the stator temperature and the bearing temperature.

EME is a provider of wind turbine generator (WTG) replacement parts reengineered for reliability. EME’s approach is to model the root cause of performance and failure issues and engineer replacement parts and systems that specifically address the underlying issues.

EME is currently partnered with a leading wind turbine generator service and repair company focused on addressing WTG rotor reliability. Through this partnership, EME provides “Wye Ring” replacement kits for a wide base of WTG rotors. These kits are reengineered-for-reliability for installation up-tower in replacement of the existing rotor main lead and jumper connections or as new equipment with shop facilitated rotor overhauls and rewinds.

EME ensures reliability through a controlled engineering process that embraces analytic based understanding and design engineering through a culture of innovation and team work focused on solving the root cause of the problem. From engineering design analysis through manufacturing to delivery and installation EME embraces a program and culture of quality driven engineered solutions and products.
