Abstract:
1. In a wind power generating system comprising at least two wind turbines mounted in common on a horizontally rotatable support in spaced relationship with each other on opposite sides of the axis of the support for rotation about horizontal axes, each turbine being connected in driving relationship with an electrical generator in turn connected with an external load; an improved control system comprising a DC boost converter with variable pulse width capability receiving the output of at least one generator, sensing means monitoring at least one of the power, speed, voltage, and current outputs of said one generator, a controller connected with and receiving signals from said sensing means and including a reference in the form of a desired performance curve for said generator, the controller also being connected in controlling relationship with said generator through said boost converter and operating to adjust the generator output, whereby said at least one generator is operated by said controller to adjust generator output and thereby adjust thrust of the turbine associated therewith and the angular position of the accelerator.
