Wind Turbine Test Station, Kayathar 


The salient features of the Test Station are as follows: Station are as follows: Station are as follows: Station are as follows: 


Test Station has currently two   test beds with grid connection to test wind turbines up to   1250kW and 400kW capacities. The number  of test  beds can be enhanced and higher capacity wind turbines can be tested  when offered. 

Each bed with   its control room is equipped with sophisticated data acquisitions systems     having validated software and state of art architecture.  

Currently two met masts are available in front of each test bed. 

  • The terrain features are gently sloping towards the western direction which is also the predominant   wind direction and the wind season is from April  to September during which testing will be conducted.




Power Performance measurements

  • Safety and Function testing

  • Yaw efficiency

  • Load Measurements

  • Special measurements required by the customer. 

  • Advantages of Testing


    The measurements of a wind turbine would assist a


    1. wind turbine manufacturer  striving for better design and performance.

    2. wind turbine purchaser in specifying requirements for design and performance.

    3. wind turbine operator in verifying and monitoring performance.

    4. wind turbine investors in wind farm projects based on what wind turbines can deliver regards to  its design and performance.
