Airfoils for Enhanced Wind Turbine and Cooling Tower Efficiency

Wind power and capacity has risen dramatically with a 2015 increase in global capacity of 23.2%, according to Navigant’s 2016 World Wind Energy Market Update. This growth in wind capacity has occurred due to the increase in both on- and off-shore wind turbines and through the increasing presence of grid-connected wind power. As a result of this increased capacity, wind efficiency and blade design is increasingly important.

An important parameter for the design of wind turbine, or... read more

L-TERRA (LIDAR Turbulence Error Reduction Algorithm)

Wind resource assessment and turbine power performance testing are typically conducted through the use of instruments on meteorological towers. Recently, LIDAR (light detection and ranging) instruments have started to replace the use of meteorological towers for these applications due to their flexibility and ability to take accurate wind speed measurements from higher heights above ground. While LIDAR instruments can measure mean wind speeds accurately under most conditions, they frequently... read more

Wind Turbine Blade Testing System Using Base Excitation

Recently, there has been a rapidly growing demand for renewable energy, including wind energy. To meet this demand, wind turbine designers are working to provide blade designs that allow a turbine connected to the wind turbine blades or to the rotor to effectively convert wind into electricity. The blades must also be designed properly to withstand inertial forces, aerodynamic forces, and structural forces so as to provide a relatively long service life and safe operation. Like all rotating... read more

Adaptive Pitch Control for Variable Speed Wind Turbines

Wind energy is increasingly recognized as a viable option for complementing and even replacing other types of energy such as fossil fuels. In the early development of wind energy, the majority of wind turbines or wind turbine generators were constructed for operation at a constant speed, but more recently, the trend is toward using variable-speed wind turbines to better capture available wind power. In most cases, wind turbine pitch angles can be adjusted to control the operation of the... read more

Variable-Speed Wind Power System with Improved Energy Capture via Multilevel Conversion

 

Power converters are used to convert alternating current (AC) electric power from a fixed-frequency and fixed-voltage to different frequencies and different voltages for powering loads, such as electric motors. They are also used in reverse to convert variable-frequency, variable-voltage, AC electric power to fixed-frequency, fixed-voltage electric power. Electric generators driven by wind turbines rotate at different speeds, depending on wind conditions, so they produce... read more

Wind Turbine Tower for Storing Hydrogen and Energy

Around the world, there is an increasing demand for satisfying energy requirements in ways that use less or no fossil fuels. These alternatives need to be reliable, cost effective, and environmentally sound to be adopted on a large scale. For example, as the need to stabilize energy resources increases, many nations and electric utilities are evaluating the increased use of wind as a portion of their power generation mix. Additionally, the use of hydrogen as a “clean” fuel to... read more

Wake Control System Based on Wake Tracking

There is a growing interest in the design of wind plant control systems to coordinate the controls of individual turbines to achieve improvements in the overall wind plant performance, such as total power production. Currently, individual turbine controls are adjusted to improve the total output of the plant above what would be achieved if each turbine pursued its individual optimal output. In general, current methods look to improve performance by accounting for the way turbines interact in... read more

Dual-Axis Resonance Testing of Wind Turbine Blades

Wind turbine blades must undergo strength and fatigue testing in order to be rated and marketed appropriately. Presently, wind turbine blades are fatigue-tested in the flapwise direction and in the edgewise direction independently. This testing involves placing the blades through 1 to 10 million or more load or fatigue cycles, which may take 3 to 12 months or more to complete for each tested direction. There is a need for blade testing techniques that are less expensive to use and require... read more

dlCC Opt: Optimization Software for Renewable Energy Projects

There are numerous options for renewable energy systems development. Location, size, type of system, and a number of other criteria need to be considered. The objective of this program is to determine the optimal size (capacity, Kilowatt (kW)) of a renewable energy generator, based on minimizing life cycle cost (LCC).

The reason for developing such a program is driven by three major issues. First, the need to evaluate a very large number (tens of thousands) of project opportunity sites.... read more

Renewable Energy Load Matching Software

The most common way of describing the quality of an existing or potential wind or solar power generation site is the total amount of energy expected to be generated based on typical weather patterns. This total amount of energy is characterized by the capacity factor (the ratio between the expected generated amounts to the maximum possible amount for hypothetical conditions of constantly blowing wind or sunshine for a 24 hour period). The capacity factor gives a correct estimate for the... read more

Coating Surfaces with Superhydrophobic Powder
Researchers at ORNL have developed a method of modifying existing coating techniques to include a bonded superhydrophobic outer coating layer. Superhydrophobic powder will not readily bond to most substrates directly, since superhydrophobic powder is almost entirely made up of fluorinated particles of silica glass, which is chemically inert to most materials. In a standard electrostatic powder spraying process, dry resin powder is sprayed on to a given substrate. The powder adheres to the... read more
