High-speed turbine rotor balancing was once rare because of the costs and logistical challenges involved in doing it during an outage. That’s begun to change as economic options emerge, and experience ...

A distinct trend is emerging in the manufacture of wind turbine generators-the use of permanent magnets (PM). At the American Wind Energy Association’s Global Windpower 2007 Conference and Exhibition ...

The main components of the turbine plant of Akkuyu unit 1 - including the stator, turbine generator rotor and low-pressure cylinder - have been delivered to the construction site in Turkey. The ...

The accident that wrecked Xcel Energy's largest electric generator in 2011 has been traced to cracks on turbine blades that broke loose from a spinning rotor and caused catastrophic damage that is ...

When most of today’s wind projects were developed, first costs were the focus; operations and maintenance (O&M) costs were largely unknown. Now, with hundreds of turbine models in operation—sometimes ...

Wind turbines deliver environmentally friendly electricity. Yet the fiber-reinforced plastics often used in very large rotor blades are almost impossible to recycle. Not so with steel blades: since ...

As gas and steam power generation plants approach the end of their operational life, plant owners face a challenging decision between upgrading or retiring the plant. Retiring a power generation unit ...
