Type approval of Windflow's innovative two-bladed turbines

IEC 61400 for Windflow Technology Limited

Application: Wind turbines, New Zealand.
Project scope: Type approval of two-bladed design to international standards and review and auditing of manufacturing sites.
Client: Windflow Technology Limited.

Windflow specialises in the manufacturing of 500 kW turbines for use in turbulent wind conditions, such as those experienced in New Zealand. We worked closely with the company to carry out type approval of all aspects of the turbine's design to the IEC 61400 suite of international industry standards. The innovative, two-bladed design included a number of features not found on more typical, thee-bladed turbines.

Our involvement covered the testing of the turbine - undertaken on site with specialists present or at an accredited test house - to ensure relevant standards were being met.

We also supported Windflow during their fabrication in a number of locations worldwide. Our review and auditing of the various manufacturing sites to make sure components were being made in accordance with the design requirements was an essential part of the project's success.

Windflow offers a range of wind energy services, including turnkey development and specialises in mid-sized wind farms of up to 100 MW located in areas with strong winds and complex terrain.
