Hi team. Im am a qualified high voltage electrician in the supply industry in New Zealand. On a recent visit to Germany to visit my girlfriend and a bit of a look into possible work opportunies if I were to move there. I took a strong interest in wind turbine maintanace as there were a lot of windfarms scattered across the country. Can I get any info on how a New Zealander with my qualifications would go about getting a job or if its even possible to be considered for one of these positions.
I was involved with building the terminal substation from a vestas wind farm in Western Australia also and was always wondered how to get into that type of role.
Thanks, appreciate any helf.
Wind speeds are slower closer to the ground. Wind speeds increase with height and accelerate as it rises over the eaves of a building. Air flow near the ground and other objects (buildings, trees, etc.) can create turbulent air flow, which can produce wind turbine vibration, noise and bearing wear. When a vertical axis wind turbine is mounted on a rooftop, the building redirects wind over the roof, increasing the wind speed entering the turbine. The energy that wind turbines generate is proportional to the cube of wind speed. A wind turbine in 20 mph of wind will generate 8x (eight times) as much energy as the same turbine in 10 mph of wind. In some wind shear locations, for every ten meters up, the wind speed can increase by 20% and the power output by 34%. Good locations for wind turbines are coastal areas with steady sea breezes, open flatlands such as the Great Plains, mesas, hilltops, ridgelines, etc. A turbine should be as high as possible and away from any obstructions. There is more wind the higher you get off the ground. Buildings, structures and trees play havoc with wind speed, direction and turbulence. A low-noise rooftop vertical axis wind turbine mounted at approximately 50% above the building height is located at the optimum height for maximum wind energy and minimum wind turbulence. A wind turbine spinning five feet above a rooftop will perform much better (2x better or more) if it’s 50 feet higher. Wind turbines with constant high wind speeds produce the best return on investment. The bottom of a horizontal turbine should be 3x above the nearest upwind barrier or 25 feet above any upwind obstacles within 300-500 feet.
Being exposed to, and harnessing the power of the wind, installation sturdiness needs to be given serious consideration. Strong gales must be allowed for. The writer has seen DIY wind turbines disintegrate – and in one case, an entire turbine head catapulted 200 feet from a freestanding tower. So, think sturdy and strong for your homemade wind turbine system. Doing it yourself is by and large just that. Professional consultants are a rare breed for the DIY type. Those that are available will almost always be working for a manufacturing outlet.
