0

3TIER, a global leader in renewable energy risk analysis, announces the release of new 90 Meter Wind Prospecting Tools. The Web-based service gives wind project developers and financiers immediate access to 90 meter resolution wind resource data across the continental U.S.—the highest resolution data currently available on demand. Such finely detailed data reveal how even small terrain features will affect wind power generation, enabling anyone with a financial stake in a project to better manage spatial risk during the earliest stages of project development.

“This low cost offering provides wind project developers and financiers with an unrivaled ability to pinpoint promising sites and begin the process of assessing their long-term potential,” says Scott Eichelberger, director of resource assessment. “It lets them more quickly and accurately evaluate sites before deciding whether to invest in more costly on-site observational campaigns and in-depth resource assessments that are required to generate ‘bankable’ production estimates.”

3TIER developed the 90 Meter Wind Prospecting Tools as a direct result of client interest in affordable access to high-resolution wind resource data. Clients can now purchase instant, online access to the entire continental U.S. or just a specific region of interest. The tools provide high-resolution wind resource data at multiple hub heights via an online interface that allows clients to view annual and monthly mean wind speed data, Weibull distribution parameters, and wind direction data. In addition to viewing the data online, clients will be able to download data in GIS format for a small incremental cost.

To produce an accurate and cost-effective 90-meter resolution dataset, 3TIER used a combination of mesoscale numerical weather prediction modeling and its own proprietary downscaling technology. Blending the two approaches achieves a commercially desirable balance between cost and accuracy, giving clients an affordable tool to effectively manage their wind resource risk during the preliminary stages of project development.

“We have created a very affordable point of entry into a suite of services that help our clients manage the risk of wind resource variability,” Eichelberger says. “At each step, we balance the accuracy we can achieve with the cost of achieving it, providing a laddered approach that ultimately yields the level of certainty each client requires to effectively manage their wind resource risk.” To learn more go to www.3tier.com.

0

In the quest for more efficient supply-chain operations, wind energy manufacturers are devoting more and more time to managing their relationships with suppliers. So what is the key to maintaining a long-term supplier relationship, and how can suppliers ensure they live up to their clients expectations?

With the increasingly trans-national nature of manufacturing and supply chain activities, many suppliers must now also prove that they possess the infrastructure capability to roll out components, modules or products on a global scale, while also providing assurances over its on-going financial stability. “OEMs look for short and flexible reaction times. Suppliers must also support improvements in the yield of customers products,” says John Kop, Commercial Director at Netherlands-based Advanced Tower Systems. Jaime Anso, from Acciona Windpower, says that “We consider that supplier relationships must bring value to both companies, as we understand that that is the only way to build long lasting relationships.”

Reflecting the importance of forging industry relationships, leading manufacturers and suppliers have committed to meeting this September to address the most crucial issues of key selection criteria and inter-company requirements.

With 14 turbine manufacturers, more than 10 suppliers in addition to offshore owner/operators, the Global Wind Turbine Supply Chain Conference—to be held September 7-8, 2011, at the Hotel Kempinski in Hamburg, Germany—is set to be the premier forum for suppliers to connect with their customers and determine how to move forward in establishing key relationships and securing long term contracts.

New Wind Turbine Pitch System from Moog

0

At the WINDPOWER 2011 conference, Moog Industrial Group—a division of Moog Inc.—unveiled a new electric pitch system that offers wind turbine operators higher performance, reliability, additional safety, and lower maintenance costs to address key challenges faced by wind turbine manufacturers and operators. The Moog wind turbine pitch system is equipped with Moog’s new AC synchronous electromagnetic brushless servo motor, which meets the requirements of onshore and offshore wind turbines. The pitch systems also include Moog’s pitch servo drive and backup systems.

Pitch control systems are responsible for the precise positioning of blades, which enable wind turbines to operate at optimum speeds to ensure the highest availability and safety. The harsh conditions that turbines operate in require the pitch system and its components to face, among other things, low and unsteady wind speeds and ambient operating temperatures ranging from -30° C up to +50° C (-22 to +122° F).

“Striking a fine balance between parameters like performance, reliability, safety, and costs are key challenges facing wind turbine OEMs and operators,” says Mauro Gnecco, business development manager, wind energy. “When compared with conventional DC pitch systems, the AC brushless technology is designed to be a very high performance system with lower maintenance costs.”

“A key challenge for wind turbine manufacturers is the selection of a motion control supplier who is capable of providing a pitch control system that maximizes reliability and minimizes mechanical complexity,” according to Sal Spada, research director at ARC Advisory Group. “Pitch control systems combined with synchronous servo motors harness advanced technologies that deliver reliable and consistent performance enabling wind turbine manufacturers and operators to maximize productivity and ROI.”

Moog designed its new wind turbine pitch servo motor to withstand extreme temperatures, vibrations, and humidity. When coupled with the associated Moog wind turbine pitch servo drive, the motor has a very high peak power density and also has the capability to be controlled in sensorless mode, which enables the servo drive to control the motor in situations where position information is lost from the servo motor’s encoder or resolver.

Moog built its pitch servo motors to meet the requirements of corrosion class C5M (according to DIN 12944 standards) and with wind-proof connector technology. The motor is suitable for Hot Climate Versions (HCV) as well as Cold Climate Versions (CCV) in both onshore and offshore environments. For more information please visit www.moog.com/wind.

Nordex Equips Germinon Wind Farm

0

With 30 N100/2500 wind turbines and a total capacity of 75 MW, the Germinon wind farm located to the west of Paris is currently the largest Nordex wind farm in France. On April 6, 2011, the customer GDF Suez officially inaugurated the wind farm. Germinon features the first Gamma Generation series turbines, which Nordex launched in spring 2010. In developing this high-efficiency class, Nordex drew on its 10 years of experience in the operation of multi-megawatt turbines. The Gamma Generation combines proven technology with specific enhancements derived from the latest research and meeting current market requirements.

With the N100/2500 turbine, utility GDF Suez selected a wind power system that makes optimum use of the mean wind speeds of 7.4 m/s prevailing at the site. As a result, the wind power systems will deliver a combined total of some 226,000MWh of clean energy each year, sufficient to cover the electricity requirements of around 265,000 people. Nordex handed over the wind farm to GDF Suez back in autumn 2010. Briefly after connection to the grid, the majority of the turbines achieved a reliability of over 97 percent.

During the execution of the project last year Nordex organized more than 360 heavy-load hauls to transport the turbine components to their destination. In fact, if all the towers segments were to be laid out end to end they would have a total length of three kilometers. For more information go to www.nordex-online.com.

O-INSPECT Multisensor Measuring Machine from Carl Zeiss

0

The successful O-INSPECT multisensor measuring machine from Carl Zeiss allows the very easy, very accurate, and thus very efficient inspection of complex parts. It can be used in the electronics and plastics industries, for medical and automotive technology, and precision engineering. A chromatic white light sensor is now available for O-INSPECT.

The white light sensor enables the measurement of parts that cannot be captured with a contact sensor or a camera. This includes very small and sensitive workpieces that feature a transparent, glossy, or low-contrast surface. Reflections or lack of contrast, which can impede the correct focusing of a camera, will no longer be a relevant factor. With the addition of a chromatic white light sensor to O-INSPECT, even workpieces such as these can be measured with maximum precision. “Carl Zeiss thus closes the final gap in the O-INSPECT measuring range,” says Dr. Dietrich Imkamp, who is in charge of visual systems at Carl Zeiss in Oberkochen.

The workpiece is illuminated with bundled white light. Special optics with chromatic aberrations in the probe split the light into its spectral colors. A spectrometer analyzes the reflected light and determines which color has the highest intensity. The measuring machine can determine the distance from the sensor to the surface using the spectral color, and it derives the exact topography of the part from this information.

The results are displayed using CAD-based CALYPSO measuring software. It enables extensive size, form, and position measurements with systematic user guidance and makes deviations visible and quantifiable. Furthermore, O-INSPECT features an additional light source on the contact-scanning sensor that can be turned on to illuminate the measuring field when the machine is reprogrammed. With this enhancement to O-INSPECT, not only its range of use improves, but also its user friendliness. Obtain more information at www.zeiss.com.

Sensor Products to Market Fuji Prescale Film

0

Sensor Products, Inc., a leader in the field of tactile pressure and force measurement, is pleased to announce it is offering Fuji Prescale pressure film. The film is a mylar tactile pressure indicating sensor film that instantly reveals surface pressure magnitude and distribution between contacting or impacting surfaces.

When placed between the surfaces it permanently turns different shades of red, with the color intensity being directly proportional to the amount of pressure applied. Prescale pressure indicating film shows precisely how bolted joints engage and deform under stress. Pressure variations are shown by the color changes left on the film. These colors can be compared to a color calibration chart to determine the exact pressure distribution.

While no instrumentation is required, the film impression can also be digitalized through imaging. Topaq, an imaging analysis program, assigns colors to pressure values. This graphic reveals pressure variations in a bolted joint interface. The non-uniform pressure distribution may be caused by a variety of factors including dimensional irregularities, surface roughness, and uneven bolt torque.

Since it is difficult to measure the force exerted by the bolts directly, torque values are often assigned for assembly based on trial and error. Prescale speeds assembly by quickly validating and confirming sufficient bolt torque to assure uniform interfacial pressure. To adjust torque values, the film is placed at the bolted joint interface and the bolts are tightened to apply pressure. The film is then removed and reviewed to see if the pressure is uniform. Common applications include measuring the interface pressure of bolted joints, gaskets, clamps, fasteners, connectors, flanges, valves, o-rings, and welding heads, among others. Wind applications include testing the bolted joints used in turbines.

Prescale is thin and flexible, allowing it to conform to both curved and straight surfaces. It may be hand or laser cut to fit unusual shapes and dimensions. It is ideal for invasive and intolerant environments not accessible to conventional transducers. The film confirms FEA predictions and has widespread applicability in research, design and test; assembly and production, quality control, and maintenance.

ECN Wind Energy to Collaborate with Sandia National Laboratories

0

On March 31, 2011, the Energy research Centre of the Netherlands (ECN) and Sandia National Laboratories signed a Memorandum of Understanding in which both parties agree on future collaboration in the field of wind energy. Sandia Laboratories focuses on applied scientific research for national security in the U.S., with sustainable energy being one of their key research areas. In the field of wind energy Sandia works on many aspects of wind turbine design, but it has a longstanding history in rotor design with a focus on higher efficiency, reliability, and monitoring technique for optimizing operational management and maintenance to wind turbines.

The joint Sandia-ECN research will focus mainly on scaling up (offshore) wind turbines and developing so-called intelligent blades to further increase the yield of wind turbines, while reducing the mechanical loads. This enables lighter wind turbine designs, longer operating lives, and lower electricity production costs per kWh. Various wind turbine manufacturers have already shown interest in this development. Tests with this type of dynamic blades, which can be adjusted with respect to shape and/or aerodynamic characteristics depending on the operating conditions, can be conducted at the ECN test site in Wieringermeer or at the test site of Sandia in the U.S. Additionally, both Sandia and ECN are already involved in collaborations with Delft University of Technology in this research area. Further collaboration will also be started in the field of aerodynamic wind farm modelling and maintenance and operational management of offshore wind farms. The first concrete projects are expected to start this summer.

The Energy research Centre of the Netherlands (ECN) is the largest research institute in the Netherlands in the field of energy and holds a strong international position. Go to www.ecn.nl. Sandia National Laboratories is managed by Sandia Corporation—a full subsidiary of the Lockheed Martin Corporation—and constitute the most important national laboratories of the U.S. Department of Energy. Next to research on reliable and safe nuclear technology, Sandia’s mission is to secure the future energy system and to make it more sustainable. Visit online at www.sandia.gov.
