Power generating system including modular wind turbine-generator assembly

A power generating system for generating electricity from kinetic energy of a wind flow, the power generating system comprising:

• a turbine assembly comprising:
• an operative shaft having a longitudinal axis, the operative shaft being rotatable about its longitudinal axis;
• at least one mounting spoke projecting from the operative shaft, in a substantially perpendicular manner with respect to the longitudinal axis of said operative shaft, each mounting spoke being rotatable with the operative shaft and having an outer extremity defining an effective diameter about said operative shaft when rotated therewith;
• at least one aerodynamic blade operatively mounted onto an outer extremity of a corresponding mounting spoke and extending in a substantially parallel manner with respect to the longitudinal axis of the operative shaft, each aerodynamic blade having a particular profile being oriented, shaped and sized to be exposed to the wind flow in order to receive the kinetic energy thereof and convert it into a rotation of the operative shaft by means of the at least one mounting spoke connected thereto;
• and
• a generator assembly comprising:
• a base shaft having a longitudinal axis and being operatively connected to the operative shaft of the turbine assembly;
• a stator operatively mounted about the base shaft;
• and
• a rotor being relatively rotatable with respect to the stator, operatively via a rotation of the operative shaft, for generating electricity as a result of the rotor cooperating with the stator;
• wherein the system is grid connected or autonomous;
• wherein physical and geometrical configurations of the components are selected according to particular conditions of the wind flow for operating the system in a nominal working range so to maximize generation of electricity from the system;
• wherein the stator of the generator assembly is internal to the rotor of the generator assembly, the rotor being external with respect to the stator;
• wherein the system comprises a main brake assembly operatively connected between the turbine assembly and the generator assembly for braking a rotation of the operative shaft, the main brake assembly being an electro-mechanical brake assembly, and being lodged within the generator assembly;
• and
• wherein the main brake assembly comprises a brake subassembly and an electro-magnet subassembly.
