Developer Buys
LIDAR, SODAR Units

Brazil’s largest wind energy developer has purchased Second Wind’s remote sensing technology as part of its standard practice in wind measurement.

Second Wind notes the purchase agreement with Sao Paulo-based Casa dos Ventos Energias Renovaveis includes not only Triton SoDARs, but also Pentalum Technologies’ SpiDAR LiDAR system. A company purchasing both SODAR and LIDAR units represents a significant endorsement of remote sensing technology as an essential complement to meteorological tower data in wind resource assessment.

Remote sensing systems calculate wind speed, wind direction and other data by measuring reflections or echoes of sound or laser pulses. According to Second Wind, Triton and SpiDAR are portable and provide wind measurements up to and above a commercial wind turbine’s hub height, addressing the wind industry’s need for data at higher heights.

No stranger to Second Wind, Casa dos Ventos already employs the company’s Nomad wind data loggers and sensors on more than 250 meteorological towers to measure, record and transmit wind data on its prospective wind farm sites, as well as at operational wind farms throughout Brazil.

German Firm Advances Turbine

MTS Systems Corp., a supplier of test systems and position sensors, has announced it will collaborate with GE Power Conversion to supply a simulation system to Germany-based RWTH Aachen University for its Center for Wind Power Drives (CWD).

MTS says the RWTH Aachen University will use this equipment in an effort to advance wind turbine performance. The university will integrate an MTS non-torque loading system and GE Prime Mover into its new 4 MW CWD. Scheduled to come online in fall 2014, the system will replicate forces impacting full-scale onshore wind turbine drivetrains.

“Simulating transient weather events, such as hurricane-force wind gusts, will allow the researchers to study the potential for damage to drivetrains and evaluate mitigation strategies,” says Rich Baker, senior vice president of MTS. “Ultimately, this will result in more reliable turbines and lower operating costs.”

Samsung To Test
Drivetrain At Narec

Samsung Heavy Industries (SHI) says it will be testing the drivetrain for its 7 MW offshore wind turbine at a new facility at the U.K.-based National Renewable Energy Centre (Narec).

According to Narec, SHI’s nacelle will be shipped to Narec and used to commission the 15 MW-rated test center. Through a six-month program, the equipment will be performance tested under simulated offshore wind conditions. The Energy Technologies Institute is providing £25 million in funding to the facility.

BURNDY Rolls Out
New Cable Ties

Manchester, N.H.-based BURNDY has added stainless steel barb cable ties to its line of products. Stainless steel barb cable ties are designed and manufactured to meet or exceed industry standards to deliver maximum reliability.

According to the company, the cable ties are nylon-based with self-locking stainless steel barbs and have a curved tip for faster initial threading to help speed installation and a no-slip tail for added grip during tensioning.

New Coating
Aids Curing Time

Coatings manufacturer Hempel has developed an epoxy coating that offers improved curing times for manufacturers of offshore wind towers.

Specially formulated for the offshore wind market, the HEMPADUR 47300 epoxy can help offshore wind tower manufacturers drive down production costs and reduce drying times by up to 25%.

According to Hempel, the coating can be applied with an airless spray and handled four hours after application at 20° C, compared to an average of five hours for standard equivalent coatings.

Moventas Completes
Validation Testing

After eight months of testing and verification, wind gear manufacturer Moventas says it has completed drivetrain testing for a gear and generator concept.

Called FusionDrive, the product enables higher drivetrain efficiency due to a better power curve and overall efficiency. It has a lower drivetrain mass and requires less material, and its compact design allows for a lighter overall turbine layout.

Produced in conjunction with permanent magnet generator supplier The Switch, the company notes the product was made for DeWind.

According to Moventas, the concept shows great potential for up-­tower repairs, which reduce maintenance and repair costs, and also decreases the levelized cost of energy by 6% compared with a 3 MW onshore turbine with a conventional drivetrain.

Fraunhofer Signs Off On Galion Lidar

Renewable energy consultancy SgurrEnergy says the Fraunhofer Institute for Wind Energy and Energy System Technology (Fraunhofer IWES) has verified the accuracy of Galion Lidar’s “remote mast” functionality.

According to the Fraunhofer IWES study, Galion Lidar’s “remote mast” capability allows measurements “where a horizontal distance between the location of the measurement device and its measurements is necessary.”

SgurrEnergy notes that the Fraunhofer IWES approval follows a series of independent verifications of Galion Lidar.
