摘要： A wind turbine and generator arrangement comprises a turbine that drives a self-excited induction generator via a shaft and mechanical gearbox. The induction generator includes an electrical circuit that includes a variable capacitance and a variable resistance. The variable capacitance may be constituted by a fixed capacitor and a triac under the control of a controller, or by a bank of capacitors switched by a relay under control of the controller. The variable resistance includes a triac controlled resistor or a bank of relay-switched resistors which constitute heating elements for heating domestic hot water. In use the generator frequency and voltage are allowed to ‘float’ while the optimal generator power output is maintained, but adjusting the impedance of the electrical circuit as the wind speed varies.

摘要： A control circuit is for an electric power plant including an asynchronous generator of an AC voltage, a motor to rotate a rotor of the asynchronous generator as a function of a first control signal of a developed motor torque, and a bank of capacitors coupled to the asynchronous generator and having a total capacitance varying as function of a second control signal. The control circuit may include a monitor circuit to monitor at least one parameter of the AC voltage, and a control signal generator circuit cooperating with the monitor circuit to generate the first and second control signals by soft-computing techniques both as a function of the frequency and of a representative value of an amplitude of the AC voltage to make the AC voltage have a desired amplitude and frequency.

摘要： The disclosed voltage generating system includes certain known components, such as an induction machine driven as a generator, the output connections of which are coupled to the normal load connections of a switching system, which can be a bridge-type inverter. The system switching frequency f.sub.1 is regulated by firing pulses from a logic circuit in turn controlled by an oscillator. By controlling operation of the inverter switches with respect to the synchronous frequency (mechanical rotational speed) of the machine, a d-c voltage is provided on the normal inverter bus conductors.In the disclosed system the conventional inverter switches (such as SCR's) are replaced by true two-way power switches, capable of passing current in either direction. In addition the firing signals provided by the usual logic circuit and applied to these power switches are modified so that the switching occurs as a function not only of the first oscillator frequency f.sub.1 but also of signals received from a second oscillator at a frequency f.sub.2. In brief, the switching is accomplished with a gate circuit including an exclusive OR arrangement, fed by both the first and second oscillators, to produce an a-c output voltage on the inverter bus conductors. The frequency of this a-c output voltage is controllable independently of the generator speed, and the output voltage amplitude is controllable independently both of generator speed and load variations.By using an induction machine with multiple windings, and plural switching systems, multi-phase voltages can be supplied over multiple conductors to energize an a-c load.
