Wind Power Generation and Wind Turbine Design Wei Tong

Forcing coal and gas-fired power plants to ramp up and down more frequently to compensate for the growing number of wind farms connected to the power according to a recent study funded by the U.S. Advances in residential turbines make them more affordable and easier to use than ever. Instead of generating electrical energy from the mechanical energy of the rotating blades, this device, called a Ewicon (short for Electostatic Wind Energy Converter) skips the whole mechanical energy part. The wind turbine would convert wind to energy without any moving parts. Offshore turbines are moving quickly from 3 MW to next-generation turbines rated at 5 MW and larger, on which blade lengths for both on- and offshore systems regularly exceed 45m/148 ft. The new blade is a unique development designed specifically for Alstom's next generation 6-megawatt (MW) offshore wind turbine. It comprises a steel Only a few prototypes have been built so far, but the inventors, Johan Smit and Dhiradi Djairam, think that if their design takes off, it could be a boon to wind power in cities, where massive turbines aren't an option. High Design: A Way to Store Wind Energy When the Wind Isn't Blowing May 1, 2013 - The intermittent nature of wind and solar power generation is one of the biggest challenges facing these renewable energy sources. It may look like a giant airplane window strung with Venetian blinds, but this structure, designed by Dutch architecture firm Mecanoo and installed at the Delft University of Technology in March, is a model of a machine that would convert wind to energy without any moving parts. Plants originally designed to provide baseload will in future have to operate on a load-following or cycling basis, ramping up and down at short notice. Harnessing the wind's energy is the objective of a new project, which aims to provide an important breakthrough in offshore wind industrial solutions. The more random power generators that get plugged into the grid by legal mandates of NET METERING, the more difficult load management will be. €�The secret to the air turbine design lies in using a fraction of the material necessary for a standard wind turbine. The Skystream 3.7 has an improved design that allows it to perform at lower wind speeds. Any mechanical moving parts, at least: California's San Onofre nuclear plant gets final death blow. Some quick history: Makani's creators several years ago came up with the idea of essentially combining kites with wind turbines in order to capture the strong and steady wind energy high up in the sky — too high for conventional wind turbines to capture. €�Vestas and Gamesa designed their turbines around the use of carbon fiber and, by virtue of that, the whole system cost is less than a system with an all glass-fiber blade,” confirms Dr. Schell, executive VP of wind energy at carbon fiber manufacturer Zoltek Corp.
