摘要： A primary and at least one backup alternating voltage source are coupled to a common load to provide interrupt free electric current to the load through a simplified interconnecting network. Phase control of all but one of the sources is accomplished by monitoring the phase difference across choke coils coupling the sources to the load.

摘要： A method and apparatus for controlling the level of power transferred through a stand-alone wind power generating system utilizing a wind turbine whose output is converted to electrical power by means of an induction generator are disclosed. In the disclosed system, the velocity of the wind incident upon the blade of the turbine is sensed by a velocity sensor. This information is then used to vary the excitation frequency applied to the generator to adjust the shaft speed of the turbine in proportion to the change in wind velocity. The excitation frequency is adjusted in accordance with a control algorithm so that the power output of the system is equal to a maximum fraction of available wind power at wind velocities below a pre-determined power/velocity point.

摘要： Each of at least two asynchronous generators connected to a common electrical load for uninterruptibility of the power supply is driven by a corresponding one of at least two drives in such a way that when any one of the generators is driven above synchronous speed by a slip fraction while its stator is electrically excited, its shaft mechanical power is converted to electrical output power at its output terminal. A control circuit is connected to the load, coupled to the output terminals of the generators and connected to the input terminals of the generators and provides an excitation voltage and controls the phase of the excitation voltage of each of the generators with respect to the load voltage. This controls the slip fraction of each of the generators loosely whereby load current from any source is completely controlled.
