摘要

Wind turbines are like every other power generation technology: where there are moving parts, there's wear and tear. Ongoing maintenance is crucial. But the source of stress on a wind turbine is unique -- constant exposure to the elements -- and utility-scale wind farm operational history is still being written. Wind farm manufacturers like Clipper Wind, Vestas and GE Energy provide ongoing maintenance services for their turbines, while independent maintenance and repair companies service many makers turbines. With most turbines, regular maintenance includes checking yaw angles. A turbine that is out of alignment with the wind -- that has a "yaw" angle to the wind -- is bearing asymmetric loads on its blades, bearings and hub. While much attention is paid to maintenance on the wind turbine itself, the connection to the utility is also critical. The substation's protective scheme is critical and must be designed correctly to protect the utility's lines.
