GL Releases New
GL Renewables Certification (GL RC) has published its new Technical Note for the Certification of Wind Turbines for Tropical Cyclones.
According to the company, an increasing number of onshore and offshore wind parks are proposed in cyclone-affected areas, mainly in the U.S., China, Korea and Japan. GL RC says the note is a supplement to its Guidelines for the Certification of Wind Turbines and addresses the question of how cyclones are influencing wind turbine designs.
The note can optionally be applied within the certification procedure and defines the additional design requirements to be considered for type and project certification, as well as requirements for site assessment, the company adds. It was prepared in cooperation with academia and industry and includes knowledge from research and from already-existing wind parks.
Vestas has unveiled its new Vestas De-icing System (VDS), which the company says can help boost the business case for operating wind farms in cold climates.
According to Vestas, VDS can be triggered automatically or manually, and the system does not require electrical components to be installed in the blade’s leading edge. The company says it tested a concept de-icing solution in Canada for the past winter season. The first prototype for the VDS has been installed at a site in Sweden and will be tested throughout the winter.
Vestas notes it has already received an order for the first four VDS units, to be installed on a V112-3.3 MW project in Austria in 2014. The system is also available for the V117-3.3 MW, subject to demand.
Moog, a provider of blade pitch control, slip ring and rotor monitoring solutions for the wind energy industry, has launched its new AC Moog Wind Turbine Pitch System in China.
Moog says the system’s modular design makes it easy to integrate into customers’ turbines, and key components of the Moog AC Pitch Servo technology have been TUV certified for compliance with the certification guideline GL2010 and the international standard ISO 13849-1.
The new AC pitch system has been integrated in Envision Energy’s 4 MW offshore wind turbine and put into operation at the Rudong Intertidal wind farm in China. The company notes that the system is also available to wind farm operators in North America.
GE Fires Up
GE has announced PowerUp, a customized software-enabled platform that the company says could increase a wind farm’s output by up to 5%, taking into account environmental conditions. PowerUp, part of GE’s “Brilliant” wind platform, is available for turbine models across the company’s installed base.
When PowerUp is activated, a GE software program performs a before-and-after wind farm power performance analysis. By adjusting performance dials that include speed, torque, pitch, aerodynamics and turbine controls, PowerUp seeks to maximize the output of a wind farm, according to the company.
