CONVERTING VARIABLE RENEWABLE ENERGY TO CONSTANT FREQUENCY ELECTRICITY BY VOLTAGE-CONTROLLED SPEED CONVERTER

A wind, river, tidal, or ocean current harnessing module harnesses a value of energy from variable water or wind flow. A water, river or wind turbine or a solar panel may generate variable direct current electrical voltage or variable alternating current. The harnessing module harnesses variable wind, water and solar renewable energy and is connected to a feed forward and feedback voltage regulator apparatus of, for example, a land module and the voltage regulator automatically provides a control voltage to a control motor for a dual ring gear speed converter. Received variable electric power input from harnessing modules is fed forward to the voltage regulator. Variable frequency output of an output generator is corrected by feeding back sampled voltage output of the output generator to the voltage regulator.
