Normandeau Associates Inc. has unveiled its Remote Condor Observation Network (ReCON), which is designed to minimize impacts on California condors at renewable energy facilities, such as wind farms.
As the California condor population grows, the birds are re-establishing themselves in Arizona and Southern California, including in areas of existing and proposed wind energy development.
In response, Normandeau developed the ReCON system, which identifies VHF-tagged endangered California condors approaching a renewable energy facility and then immediately alerts personnel, who can take measures to minimize the potential for adverse impacts on the condor, the company explains.
“The ReCON system can detect a VHF-tagged condor from up to 30 miles away,” says Christine Sutter, a technical director with Normandeau and one of the principal developers of the ReCON system. “Typically, visual detection – even by an experienced condor observer – is limited to two to three miles.”
When a condor is detected, the system alerts the facility, which can then respond by sending out human observers to further assess the situation or can implement an automated response to initiate turbine shutdown.
In addition to the new ReCON product, Normandeau offers a remote bat acoustic monitoring system, which is often used at wind energy facilities.
NRG Systems has introduced a product that it says will give wind developers a deeper understanding of resource assessment in prospective locations.
Called Grand Symphonie, the product applies advanced technology to reduce both overall measurement uncertainty and total cost of ownership, notes NRG, adding that the integrated system employs smart sensors and wireless communications, and a cloud-hosted data management portal improves the quality, reliability and security of resource assessment data.
According to NRG, the sensors store data redundantly for up to one year, and system-wide features allow for quality control. Grand Symphonie also features automated data transfer from the GS-Logger to WindPortal, a cloud-hosted Web application that provides enterprise-grade security and backup of data, the company says.
In addition, NRG has introduced a new version of its WindSensor anemometer, the P2546C.
Designed for resource assessment, site calibration and power performance measurement, the WindSensor anemometer is designed to operate in turbulent environments. The new version of the WindSensor replaces the mercury switch with a coil-based signal generator that produces a sine wave output.
The P2546C is now available and ships free via surface freight to most destinations around the world, the company notes.
Gearbox and bearings provider Romax Technology has launched a new connector designed to enable its RomaxDesigner and RomaxWind product design and simulation software to integrate with the ANSYS mechanical suite.
The new connector allows RomaxDesigner and RomaxWind users to modify and connect these components, pass them to ANSYS, run Finite Element analysis in ANSYS and transfer the results back into RomaxDesigner for full system static and dynamic analysis, the company explains.
Sika Rolls Out
Sika Corp., a supplier of adhesive and sealant solutions, has launched a product to help with the repair of wind turbine blades.
The new SikaForce7818 L7 MixCan kit has been developed specifically for on-location wind blade repair applications. The kit contains pre-measured amounts of the two component adhesives needed in blade repair, and the end user adds the two components and mixes in the can.
The pre-measured amounts of both components give the user accurate mix ratio control for proper product performance. The structural adhesive, which displays properties conducive to sanding and finishing, is used for deeper surface repairs on wind blades, Sika notes.
Korean manufacturer Hyundai Heavy Industries (HHI) has developed a 5.85 MW permanent magnet synchronous generator (PMSG) for offshore wind turbines.
Based on the generator’s improved durability and minimized use of expendables, the machine’s product life is extended from 20 to 25 years, HHI says. The company plans to commercialize the generator by 2014 after finalizing field tests.
The manufacturer says the development of the PMSG will be a catalyst for it to enter into the 5 MW and 6 MW offshore wind turbine markets.
Wire Rope Hoist
Available In Canada
Columbus McKinnon Corp., a designer and manufacturer of material handling products, has made its Yale Global King electric wire rope hoist available in Canada as part of the company’s Quick Ship Program.
The program offers select Global King units as a standard monorail unit or as a complete plug-and-play crane kit, the company says, adding that both of the monorail hoist and plug-and-play crane kit offerings come in three-, five-, 7.5- and 10-ton units.
A three-year warranty is offered on the Global King hoists, the company adds.
Moog Inc., a designer, manufacturer and integrator of precision-control components and systems for the wind energy industry, has introduced its new wind turbine remote terminal software.
The software is designed to give wind farm operators and manufacturers greater control and understanding of the operation of pitch systems, which are critical to the efficiency and safety of wind turbines.
The remote terminal software can be accessed by both Moog engineers and the customer’s service personnel using a single graphical user interface. The software offers users the ability to remotely diagnose potential operational issues in the pitch system and take corrective actions, either by parameter editing or through preventive-maintenance actions, the company explains.
The tool is also intended to help operators plan on-site service work, allowing for targeted maintenance. Software updates can also be applied remotely to ensure that customers can take advantage of continuous improvements in the tool.
New Product Avoids Slip Rings
Diamond-Roltran has just completed its Roll-Ring rotor assembly, which is designed for use with the company’s generator collector test platform for wind turbines.
Roll-Rings are designed to help wind farm owners and managers reduce costs and increase uptime by eliminating slip-ring brush and rotor maintenance. And because Roll-Rings do not generate wear debris, they are capable of rolling up to 1 billion revolutions, according to the company.
The Roll-Ring wind collector rotor test assembly has two channels capable of carrying 600 amps each. Each channel has three grooves for Roll-Rings to roll in and conduct power between the stator and rotor assemblies. Each Roll-Ring will run in its own groove and, at three inches in diameter, is capable of conducting 200 amps each. The 62-pound rotor assembly was balanced to 2,000 rpm.
Diamond-Roltran says the next step in the development program is to install the rotor into the stator housing and then install Roll-Rings to conduct current between the rotor and stator conductive grooves. The assembled test unit will be operated at 1,800 rpm with 600 amps fed into one channel, shorted across the rotor posts and then back across the other channel.
Once testing is complete for the two-channel unit, a full-scale commercial prototype will be built. The Roll-Ring wind collector will have three phases capable of 600 amps each and one 600-amp ground leg, the company adds.
