Wind Turbine Test Station, Kayathar +

The salient features of the Test 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.
Small Wind Turbines+

Key modifications:

  • Aerogenerators on Telecom Towers eligible for Central Financial Assistance (CFA)
  • CFA for models having valid type test reports from NIWE or Intrational Recognized Testing Agencies
  • Up to 500 KW of new type tested models to be supported without manufacturing base in India
