More Power from Light Winds
More Power from Light Winds

Would a 20% increase in low-wind performance improve your bottom line? Two Rutgers researchers have developed a blade deflector that takes advantage of tangential forces wasted by typical blades. Laboratory-scale models confirm computer simulations, and the technology was recently licensed to a commercial technology vendor. Even a fractional 5% power increase translates to a 20% profit improvement, notes Wind Power Engineering.

Impact of Wind Turbines on Radar Returns
Impact of Wind Turbines on Radar
Returns
Remcom (USA)

Wind turbines located near a radar installation can significantly interfere with the ability of the radar to operate properly. Remcom has used our tools and expertise in radar scattering to perform a number of research efforts into the impact that wind turbines and wind farms have on radar returns for Air Traffic Control (ATC) radar, early warning radar, weather radar, and instrumentation radar. Download this paper for highlights and relevant samples of these projects.

Designing for Hurricanes

Designing for Hurricanes Are all offshore wind locations basically alike? Not if you factor in the hurricanes and extreme tides that affect the shores of North America. The National Renewable Energy Lab (NREL) recently recommended a completely different design approach for American offshore facilities. Extended power storage for maintaining emergency yaw control is one example of new recommendations from the NREL.

Spinning in the Wind
The International
Electrotechnical Commission

Wind turbines are sophisticated machines and converting mechanical wind energy to electrical power requires a number of components. One of these, the gearbox, is essential for uprating the low speed of the main shaft attached to the rotor hub. Discover IEC's published International Standard requirements for wind turbine gearboxes.

Distributed Wind — What's Holding It Back?

Distributed Wind — What's Holding It Back? Net metering brought distributed solar energy to the grid, but distributed wind generation has been less successful. According to Renewable Energy World, the primary barriers to neighborhood wind are noise, appearance, and durability. Noise control is possible, but requires tradeoffs between efficiency, blade speed, and storm resistance. Appearance may be the real hurdle, since turbine towers rarely blend into the landscape.

Not Just a Job...

Not Just a Job... For anyone thinking about running a wind farm, this day-to-day job description from Power Technology is enlightening. Managing a 54-turbine farm off the coast of England is neither boring nor repetitive. Priorities change constantly, but one of the biggest seems to be attracting and keeping good staff. Prior experience is important, but other attributes are equally necessary for a successful turbine industry career.

Bankability — the Five Key Factors

Bankability — the Five Key Factors Do you know the five primary factors affecting wind farm bankability? The most important, says North American Windpower, is your ability to mitigate financing and development risks. By the time permitting and financing are completed, an exhausted developer has just started climbing the profitability ladder. Access to efficient distribution lines, experienced staff, and robust technology are a few of the remaining steps that go into a profitable project.

Blade Flaps Yield SMART Results

Blade Flaps Yield SMART Results Fixed airfoil blades may soon be a thing of the past. Tests of the SMART rotor — three 9 m turbine blades with trailing edge flaps along 20% of the blade length — promise improved strain relief and vibration damping capabilities. In one Sandia National Labs test, blade load reductions of 14% were noted, although actuation times were challenged by delays in the actuator mechanisms and electronics.

Cold Climate Considerations

Cold Climate Considerations Cold climates, with their high winds and residential energy requirements, can be very attractive to wind farm operators. Unfortunately, icing is a major threat to blades, towers, and even data cabling and transmission lines. With 57% of new generating capacity planned for ice-prone regions, North American Clean Energy expects the International Energy Agency to increase its focus on cold-climate research.

Separating Infrasound Fact from Fiction

Separating Infrasound Fact from Fiction Wind farm infrasound exists, but a study from the Australian Environmental Protection Agency puts it into perspective. Urban areas are far noisier, with air handlers and cars identified as primary infrasound generators. In rural areas, natural breezes create more infrasound than wind farms at distances of 1.5 km or more. The report's conclusions should bring a smile to every turbine operator.
