1. A method for installation of a power control module in a tower for a wind turbine, comprising:

providing a power control module,

providing a tower section,

wherein the method further comprises:

a) providing a temporary support device,

b) placing the power control module on the temporary support device,

c) placing the tower section around the power control module,

d) connecting the power control module to the tower section, and

e) removing the connected power control module and tower section from the temporary support device,

wherein steps a-e are carried out in the mentioned sequence.

2. The method according to claim 1 , further comprising performing the steps b, c and e by vertically moving the respective item.

3. The method according to claim 1 , further comprising the further steps of:

f) moving the connected power control module and tower section to a vessel for transportation to an off-shore erection site, and

g) placing the connected power control module and tower section on an off-shore located foundation.

4. The method according to claim 1 , wherein step d includes hanging the power control module suspended in the tower section.

5. The method according to claim 4 , further comprising hanging the power control module suspended in at least three bars.

6. The method according to claim 5 , further comprising attaching the bars to an internal flange of the tower section.

7. The method according to claim 1 , wherein step d includes attaching an internal support on the tower section, and placing the power control module to stand resting on the internal support.

8. The method according to claim 7 , further comprising attaching the power control module to the internal support.

9. The method according to claim 1 , further comprising the further step of mounting an elastic member between the power control module and the tower section.

10. The method according to claim 9 , wherein the elastic means includes a plurality of rubber elements.

11. The method according to claim 10 , wherein at least some of the rubber elements are vulcanised to steel brackets.

12. An aggregate component for a wind turbine, which component includes a power control module and a tower section, which power control module is connected to and supported by the tower section in a state as a pre-fabricated and mobile component wherein the power control module hangs suspended in the tower section;

wherein the power control module includes a first compartment, the first compartment including a first platform and a first framework of rigid beams extending upwards from the first platform; and

wherein the power control module includes a second compartment, the second compartment including a second platform and a second framework of rigid beams extending upwards from the second platform.

13. The aggregate component according to claim 12 , wherein the component further includes one or more temporary support.

14. The aggregate component according to claim 12 , wherein the power control module hangs suspended in the tower section using at least three bars attached to an internal flange of the tower section.

15. The aggregate component according to claim 12 , wherein the power control module includes equipment for control of the wind turbine and for transferring generated current to an appropriate electric output for a power grid.

16. The aggregate component according to claim 12 , wherein the power control module includes a transformer, a converter, and an internal power supply system.

17. The aggregate component according to claim 12 , wherein the power control module includes a third compartment, the third compartment including a third platform and a surrounding fence.

18. The aggregate component according to claim 17 , wherein the first framework of rigid beams of the first compartment is attached to the first platform of the second compartment, wherein the second framework of rigid beams of the second compartment is attached to the third platform of the third compartment, and wherein the entire power control module is configured to be lifted by wires attached to the third compartment.
