PSI Repair Services says its test program identifies component failures down to the microchip level on wind turbine electronics. It also detects which components are likely to fail in the near future.
An independent repair company for electronics, hydraulics, and precision mechanical assemblies, will showcase its off-warranty repair support for wind energy operations and maintenance (O&M) professionals at the CANWEA 2011 Annual Conference and Exhibition. PSI Repair Services will exhibit in booth 1336 at the 2011 CanWEA Conference and Exhibition which will be held October 3 to 6 at the Vancouver Convention Centre in Vancouver, British Columbia.
Recent stats suggest that 79% of wind turbines are set to move out of warranty in less than five years. Because wind energy is independent of fuel costs, a repeatable and cost effective O&M strategy can have an immediate impact on an operator’s bottom line.
The company is said to offer fast, affordable repairs for out-of-warranty electronic and mechanical wind turbine components from all the major manufacturers, including General Electric, Vestas, Zond, Neg Micon, and others. Components repaired include printed circuit boards, PLCs, control cards, VRCC components, IGBTs, thyristors, hub converters, pitch motors, hydraulic pumps, servo motors, transducers, and more. All repairs come with a free evaluation and one-year warranty.
The company also offers engineering services that can enhance the performance of new and old wind turbine components with superior and more efficient technology. For unsalvageable parts, PSI offers state-of-the-art remanufacturing services. For more information on CanWEA 2011, visit www.canwea2011.ca

Goudian United Power Technology Co. assembles nacelle equipment at its Baoding plant. Eaton hydraulic components will perform yaw and shaft braking functions.
Industrial manufacturer Eaton Corporation says it will provide key wind-power technologies to Guodian United Power Technology Co. Ltd., a wind turbine manufacturer in China. The agreement will generate about $1.5 million in revenues annually for the U.S. firm.
Eaton’s Hydraulics Group based in Shanghai will supply hydraulic power units equipped with Vickers and Integrated Hydraulics screw-in cartridge valves for yaw and shaft braking functions on Guodian wind turbines produced in Hebei Province. Eaton will also supply Aeroquip MatchMate Plus hose and Winner fittings for turbine brakes.
Eaton says it also offers customers power-unit-design capabilities, local production expertise, and technical and application engineering support.

Continental Disc Corp. also manufacturers rupture-disc devices for a variety of process industries, including chemical, petrochemical, aerospace, electronics, and others.
A new rupture-disc assembly for wind-turbine hydraulic brakes protects equipment from damage and down time in the event of overpressure. Intended for the hydraulic brakes and yaw brakes of wind turbines, the rupture-disc assembly, model CD31179 provides accurate and leak-free overpressure relief for the control valve and hydraulic accumulator system. The hydraulic braking device, from Continental Disc Corp, Liberty, Mo, comes in a range of sizes, materials, and burst pressure ratings to protect wind turbine equipment.
Low pressure course on hydraulics for wind turbines

A four-and-a-half-day training course is aimed at sales and maintenance personnel who must understand hydraulics systems used in wind turbine operation. Wind Turbine Fundamental Hydraulics will be offered by industrial manufacturer Eaton Corp.
“Nearly half of the utility-grade wind turbines in service depend on hydraulic pitch and yaw controls. Many of the others use electric drives controls but may use hydraulics for braking or a forced lubrication system,” says Eaton’s Manager-training Services Tom Blansett. “The new course will provide a solid foundation in hydraulic fundamentals and operating principles with special emphasis on wind-turbine operations, including pitch and yaw control, braking, and cooling and filtration systems.”
Classes are slated for July 27 to 31, aug 17 to 21, and Oct 5 to 9, all in Maumee, Ohio.
The course will focus on component construction and operation with a goal of understanding the interaction of individual components in an integrated wind turbine hydraulic system. Topics include:
- Hydraulic principles and fundamentals
- Graphic symbols
- Hydraulic fluids and reservoirs
- Gear, vane, and piston pumps
- Pressure controls
- Directional controls
- Flow controls
- Cylinders
- Hydraulic motors
- Contamination control
- Electro-hydraulic valves
- Screw-in cartridge valves
- Accumulators
