Tower section for automatically raising a wind turbine and automatic raising method for same

A system for assembling a wind turbine comprising;

• a nacelle, a rotor having blades and an upper tower section on which the nacelle and rotor are supported, the upper tower section having a base with a first width and a top on which the nacelle and rotor are supported, the top having a second width less than the first width;
• at least first, second and third spaced-apart tower foundations configured to support the wind turbine after the assembling, each of the first, second and third tower foundations having a center connection, the connection being located in the center;
• a plurality of modular frame structures that are configured to be vertically joined together in a sequential manner to form a lower tower section, each the plurality of modular frame structures including at least first, second and third vertical columns, each of the vertical columns comprising an upper end comprising a first flange and a lower end comprising a second flange, the plurality of modular frame structures configured to be attached to one another by a coupling together of the first and second flanges, the second flanges being configured to be attached to the connection of the tower foundations, the plurality of modular frame structures comprising an upper-most frame structure after the assembling;
• a transition piece configured to couple the upper tower section to the lower tower section, the transitional piece including an upper part that is configured to be coupled to the base of the upper tower and a lower part comprising a plurality of flanges that are configured to be coupled to the first flanges of the upper-most modular frame structure and also to the connections of the tower foundations, the upper part of the transition piece having a first width and the lower part of the transition piece having a second width greater than the first width;
• and
• a lifting system including at least first, second and third lifting subassemblies that are respectively supported on the ground, the first, second and third lifting subassemblies having disposed between them first, second and third joint structures that each moves vertically upward and downward between upper and lower points, the first, second and third joint structures configured to be respectively attached to the first, second and third columns of the first, second and third frame structures.
