Abstract

A nacelle for a wind turbine and a method for erecting a wind turbine are disclosed. The nacelle comprises a main unit arranged to be connected to a wind turbine tower, via a yawing arrangement, and at least one side unit mounted along a side of the main unit in such a manner that direct access is allowed between the main unit and the side unit(s), each side unit accommodating at least one wind turbine component, and at least one side unit being capable of carrying the wind turbine component(s) accommodated therein. The main unit and at least one of the side unit(s) are distributed side by side along a substantially horizontal direction which is substantially transverse to a rotational axis of a rotor of the wind turbine. A sufficient interior space of the nacelle is obtained while allowing the nacelle to be transported due to the modular construction. The weight of the wind turbine components is arranged close to the tower due to the transversal arrangement of the side unit(s) relative to the main unit.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method for erecting a wind turbine comprising:
 erecting a wind turbine tower at the wind turbine site;   transporting the main unit and the at least one side unit to the wind turbine site;   assembling a main unit and at least one side unit to form a nacelle;   mounting the nacelle on a yawing arrangement of the wind turbine tower,   wherein the at least one side unit is connected to at least one side of the main unit in such a manner that the main unit and the at least one side unit are distributed side-by-side along a substantially horizontal direction which is substantially traverse to a rotational axis of a rotor of the wind turbine after being mounted to the yawing arrangement.   
     
     
         2 . The method of  claim 1 , wherein the step of assembling the main unit and the at least one side unit occurs prior to transporting the main unit and the at least one side unit to the wind turbine site. 
     
     
         3 . The method of  claim 1 , wherein the step of assembling the main unit and the at least one side unit occurs prior to mounting the nacelle on the yawing arrangement of the wind turbine tower. 
     
     
         4 . The method of  claim 1 , wherein the at least one side unit includes at least one wind turbine component mounted therein prior to transporting the at least one side unit to the wind turbine site. 
     
     
         5 . The method of  claim 4 , wherein the at least one side unit includes at least one wind turbine component mounted therein prior to mounting the nacelle on the yawing arrangement of the wind turbine tower. 
     
     
         6 . The method of  claim 1 , wherein the step of assembling the main unit and the at least one side unit to form a nacelle occurs on the ground. 
     
     
         7 . The method of  claim 1 , further comprising:
 disconnecting the at least one side unit from the main unit; and   lowering the at least one side unit from the main unit directly adjacent and substantially parallel to the main unit.   
     
     
         8 . The method of  claim 4 , further comprising:
 hoisting a different side unit to a position adjacent to the main unit directly adjacent and substantially parallel to the main unit; and   connecting the different side unit to the main unit in such a manner that the main unit and the different side unit are distributed side-by-side along the substantially horizontal direction which is substantially traverse to the rotational axis of the rotor of the wind turbine.   
     
     
         9 . The method of  claim 1 , wherein the main unit has an interface to which the at least one side unit is connected, the method further comprising:
 disconnecting the at least one side unit from the interface of the main unit;   lowering the at least one side unit;   hoisting a crane to a position adjacent the interface; and   connecting the crane to the interface.   
     
     
         10 . The method of  claim 1 , wherein the at least one side unit includes a first side unit and a second side unit and the main unit has a first side and a second side opposing the first side, wherein the step of assembling the main unit and the at least one side unit further comprises:
 assembling a first side unit to the first side of the main unit and the second side unit to the second side of the main unit in such a manner that the main unit and the first and second side units are distributed side-by-side along the substantially horizontal direction which is substantially traverse to the rotational axis of the rotor of the wind turbine.
