Patent ID: 8878384

Claim:
A wind power electrical power generation system comprising: a fluid pump having an input port and an output port; a rotating blade mechanically connected to the fluid pump, the rotating blade and fluid pump being configured to operate the fluid pump to move fluid from the input port to the output port in response to rotation of the rotating blade; a proportional flow valve fluidly coupled to the output port of the fluid pump, the proportional flow valve being configured to divert a first portion of the fluid from the output port to a first fluid motor and a second portion of the fluid from the output port to a second fluid motor; the first fluid motor fluidly being coupled to the proportional flow valve; the second fluid motor fluidly being coupled to the proportional flow valve and configured in parallel with the first fluid motor; a first electrical generator mechanically coupled to the first fluid motor; a second electrical generator mechanically coupled to the second fluid motor; and a proportional integral controller operatively connected to the proportional flow valve and configured to operate the proportional flow valve with reference to a difference between a set point for a parameter for the first fluid motor and a signal indicative of a current value for the parameter for the first fluid motor to enable the first fluid motor to operate at a predetermined rotational speed in response to the first portion of the fluid from the proportional flow valve while the second fluid motor operates at a varying rotational speed in response to the second portion of the fluid from the proportional flow valve.
