Common Problems With Wind Turbines

It's easy to see why wind turbines are at least potentially hazardous for birds: massive blades with tips spinning at up to 179 mph (80 meters per second), hundreds of feet (at least 30 meters) in the air, are an obvious problem for anything flying near them [source: mit].the fact is, birds do fly into the path of the blades and die a grisly death.. In short, the timing of "symptoms of life" and the appearance of wind turbines show no relationship. problem #4: the geographic dispersion of complaints is too unlikely. if wind turbines did cause medical problems, we would expect to find a relationship between prevalence of the syndrome and populations living near wind farms. but we don't.. The most common turbines in the usa are manufactured by vestas, gamesa and general electric, while some older facilities use turbines from neg micon and zond. one of the most common turbines , the ge 1.5 megawatt model, has 116 foot blades on a 212-foot tower, while the vestas v90 has 148 foot blades on a 262 foot tower..

In that way the wind turbine will not consume reactive power, which is the most common problem with wind turbines that use induction machines. this leads to a more stable power system. moreover, with different control schemes a wind turbine with a permanent magnet synchronous generator can provide or consume reactive power.. Wind turbine failures - tackling current problems in failure data analysis m d reder, e gonzalez and j j melero circe-universidad de zaragoza, c/ mariano esquillor 15, 50018, zaragoza, spain. Most of these problems have been resolved or greatly reduced through technological development or by properly siting wind plants. this aerial view of a wind turbine plant shows how a group of wind turbines can make electricity for the utility grid. the electricity is sent through transmission and distribution lines to homes, businesses, schools.
