Study Description: 

Problems due to extreme weather conditions are not new to the wind turbine industry. When high speed winds carry ice, snow, and fog, technical problems are likely to develop. One of the common problems is failure of turbine’s anemometer. When the anemometer failure occurs, the information on wind direction and force does not get relayed to the huge blades. This leads to inefficient usage of wind energy leading to energy losses and downtime.

Designed experiments were taken up by the R&D team of a large wind energy company to address this issue. Through several weeks of experimentation in simulated conditions, it was found that heating circuit design was the critical factor that needed change. New controls were introduced with the changed circuit design. Five day tests were made mandatory in several simulated conditions for each anemometer to be approved. Mistake proofing was done to eliminate the possibility connector’s attachment with junction box. On implementation of the improved design at all affected sites, no defects were found in several months that followed.
