Abstract

A wind turbine for generating electrical power having a vertical 'Savonius rotor type' wind rotatable turbine with multiple fixed pitch blades and a rotatable wind inlet duct having an identical number of multiple infuser-shaped aerodynamic guides as the pitch blades and is mounted in the duct to direct equal air flow at higher speed to load each of the multiple fixed pitch blades to form an infuser system. The wind-rotatable turbine is mounted within the inlet duct and infuser system. A synchronous generator is driven by the vertical turbine and an electrically driven hold-down spring system enables the wind turbine to disconnect from the generator when the wind speed is above maximum safe operating speeds. An automatic control system that controls electrical power to the electrically driven hold-down spring system enables the wind turbine shaft to be automatically loaded or unloaded to the generator shaft based on the incoming wind speed measurement as determined by a wind speed measuring system mounted to the rotating duct system and connected to the automatic control system.
