Tower Vibration Analysis Of20Kilowatt Island Wind Turbines

Wind power generator of the island is one of the main power equipment,Because of its installation, transportation cost is inland with type wind turbine hashigh cost, the running safety is very important. In the island of wind environment,Vibration of the blower turbine breakage caused by the main factors, The Island is aspecial wind environment, wind turbine tower wind vibration resistance performancein particular to a request. Further to island turbine in view of the island under thespecial environment vibration condition, it is very necessary.This paper establishes a20KW island wind turbine tower based on finite elementmodel; structural mechanics and classical fadeyev formula, on the wind turbine towermodal analysis, and using the classical structure mechanics formula on tower towernatural frequency for proof-reading, calculate the20KW Island turbine in the islandenvironment in the type of vibration, and vibration conditions.
