A wind-driven power generating apparatus which includes a main support for securement to a fixed structure. A main drive shaft is retained by this main support and is connected at one of its outer ends to a support block having a plurality of angularly spaced, radially extending, support shafts, each one of which carry a windmill-type blade. The other end of the main drive shaft extends into a housing having a support frame for retaining a gear drive mechanism. One of the gears in this gear drive mechanism is connected to the main drive shaft. Also included within the gear drive mechanism located within the housing is a second gear which drives a pair of alternators for generating electrical power as the support block is rotated by the wind vanes. A first speed control mechanism is associated with each of the vanes and rotates the vanes axially about their longitudinal center line in proportion to the speed of the wind in order to protect the apparatus against excess rotation due to excess wind speed. A second speed control mechanism is associated with the apparatus and prevents energization of the field windings forming part of the alternators which generate the current, if rotation of vanes does not achieve a minimum speed.
