The Timken Co. said it has reached an agreement with Northern States Power Minnesota, an Xcel Energy Co., for remote monitoring of wind turbines at Xcel Energy's 200 MW Nobles Wind Farm in southern Minnesota.
Timken will supply 134 of its Online Intelligence Systems (OIS) for the 1.5 MW wind turbines. The initial agreement includes two years of condition monitoring and advanced on-going analysis services.
Timken's Online Intelligence System is a condition monitoring/data collection and reporting system specifically designed for low-speed wind turbine applications. The Timken OIS analyzes a combination of vibration, high-definition shock pulses and analog/digital inputs to identify main-shaft bearing, gearbox, and generator problems before they develop into life-limiting conditions.
The NSP Minnesota system is permanently mounted for real-time data retrieval, but the technology can also be packaged as a portable system for trouble-shooting turbines without online systems during normal service intervals.
