Northern Power Systems licenses turbine technology to South America

Expanding the global reach of its permanent magnet direct drive (PM/DD) technology, Northern Power Systems, recently announced that it has entered into a strategic partnership with WEG Equipamentos Elétricos S.A., one of the world’s largest manufacturers of electronic equipment. WEG and Northern Power are cooperating to bring proven, next-generation wind turbine technology to the South

Romax secures another patent for wind industry development

Romax Technology’s desire to ‘push the boundaries’ leads to the development of a twin offset gear planet carrier for the wind industry. “The Romax philosophy,” says Romax Technology Founder Dr Poon, “is to look at existing designs and see how we can improve them. As a company, we are constantly looking at conventional practice and

Hydraulic drivetrain turbine sets sights on offshore wind

Hydraulic drivetrains in wind turbines present great possibilities. For one, a hydraulic pump and motor would allow getting rid of the troublesome gearbox, thereby improving reliability. With such an arrangement, the turbine rotor would turn a variable-volume pump which would drive a hydraulic motor to spin the generator. Accumulators could briefly store excess pump energy

FusionDrive factory validation complete, helps reduce the LCoE

After eight months of testing and verification, FusionDrive, the industry’s most advanced gear and generator combination is now a validated drivetrain. The smallest and most lightweight combo in the market has proven to reach 96.6% efficiency, leading to an excellent energy yield. The gear and generator combination, in commercial production for DeWind, is a joint

Moog earns TÜV Rheinland certification for safety on wind turbines

The Moog Pitch Servo Drive, a component of Moog’s Pitch System responsible for guaranteeing the safe operation of wind turbines, obtained a TÜV certification for compliance with the guideline issued by Germanischer Lloyd. This validates that Moog designs achieve Performance Level D for the wind turbine feathering safety function. The safety of wind turbines is

Encoder interface outputs to Siemens Drive CLiQ

In an effort to increase encoder compatibility with Seimens controls, Heidenhain has developed the EIB 2391S interface box. Ideal for applications with Sinamics drive components, the EIB 2391S enhances the serial interface offering for many of Heidenhain’s absolute encoders. With IP 65 and its compact size, the EIB 2391S is suitable for any industrial environment.

Facility to test 7.5 and 15-MW drivetrains

A $98 million facility capable of accelerated testing of turbine drivetrains of up to 15 MW will soon open its doors on what used to be a U.S. Navy shipyard in North Charleston, S.C. The first test bay, and the first to open will be capable of handling drivetrains up to 7.5 MW. Located on

How simulation improves gears for wind turbines

This article comes from engineering software developer Dassault Systèmes Control over the position of a turbine’s nacelle and blades is essential for the most efficient conversion of the wind’s kinetic energy into electrical energy. Yaw and pitch drives adjust the physical orientation of those components in response to fluctuations in the speed and direction of

Company says $34 billion saved with its installed electric drives

A power and automation technology group has released its annual estimate of the savings achieved by its installed base of drives. ABB says about 310 million MWh of electric power was saved by ABB drives in 2011, an increase of 19% over the previous year. Electric drives regulate the speed and power consumption of electric

2012: Trends in motors and drives

With larger, more powerful turbines coming online, requirements for pitch control are increasing. Experts say the wind-power industry is also beginning to adopt aerospace test technology, the same kind used to vet airplane designs, to simulate loads on wind turbine blades before installation. Pitch control is a key safety system in turbines. Ray Opie, senior
