Research and Markets has announced the availability of the latest report titled "Wind and Solar Power for Mobile Telecom".
Mistaya Engineering and Second Wind have partnered to integrate the Windographer analysis software of Mistaya Engineering and the wind data collection technology of Second Wind into a solution for helping energy companies select and evaluate the most productive locations for installing their wind turbines.
The wide bodied nacelle incorporated in the wind turbine comprises a central nacelle, two housings on the sides and a hub and allows easy access for maintenance. The electrical yaw and pitch control incorporated in this wind turbine maintains the rotor speed stably and cuts off the rotation during excessive winds.
The two sectional blade utilized in the wind turbine measuring a total of 62.50 m in length has an inboard section measuring 30.50 m and an outboard section measuring 32.00 m in length. The rotor of the wind turbine measures 128 m in diameter and offers a swept area of 12,868 m².
This wind turbine starts operating at 4 m/s wind speed, produces its optimal power of 3 MW at 12.5 m/s wind speed, and ceases its operations when the wind crosses the speed range of 20 to 25 m/s.
The permanently excited synchronous type of generator incorporated in the wind turbine achieves a rotary speed ranging from 240 to 792 rpm and this generator is connected to the grid through a 3 x 400 V inverter.
Vaigunth Ener Tek offers the AR 7500W small wind turbine. This battery charger wind turbine incorporates a fixed pitch 7.5 m diameter rotor and offers a swept area of 44.2 m². This upwind type of rotor incorporates three blades and each blade measures 3.2 m and weighs 40 kg.
This wind turbine comprise a fan cooled 4 pole, 3 phase induction generator manufactured by Rexnord. This generator outputs voltage in the range of 80 to 500 V AC in a frequency range of 20 to 70 Hz.
The cut in wind speed of this generator is 3.5 m/s and this wind generator can withstand a maximum wind speed of 50 m/s. For the purpose of battery charging applications a controller is utilized to convert the incoming 3 phase AC power from the wind generator.
Seajacks International has reached an agreement with Lamprell Energy PLC to develop Seajacks Zaratan, a self-propelled jackup, designed to serve the wind farm installation sector as well as the oil and gas industry.
