Field trials of the NMITLI 500 kW Horizontal-Axis Wind Turbine System

After the commissioning of the 500 kW Wind Turbine at the field test station, Sangeeth Wind Farm, Kethanur, Tamil Nadu, preliminary field trials commenced in 2009. The intention of these field trials was to ensure that the runs were smooth and that there were no instabilities in terms of the mechanical integrity of the system. Also, the wind turbine was run to check whether dynamically there were any points of concerns. At the same time, the Data Acquisition System (DAS) was in place and its proper functionality was also to be ensured. Hence, during the 2009 and 2010 wind season, the power curves were measured with the DAS. The present document gives a brief account of the field trials during the 2009 and 2010 wind season.
