Abstract
An autonomous electromechanical complex is a partial version of an autonomous electric power system with electric machines as a source and consumer of electricity. Realization of idea of replacement of difficult synchronousgenerator on more simple reliable and relatively a cheapautonomous asynchronous generator with the short-curcuit rotor is done by impossible by the row ofthe difficulties predefined by the general lacks of asynchronous machines, in particular, by the necessity of separate source of reactive-power for the off-line system with an autonomous asynchronous generator. On the example of calculation and analysis of descriptions of physical model of autonomous electromechanics complex the shown possibilities and terms of compatible work of asynchronous generator and motor of comperative power are at the different variants of capacity excitation The distribution of capacities in asynchronous generator and motor for individual branches of the electrical circuit, unconnected conditions ferroresonance voltages was proposed to ensure the stable work of the dissimilar conditions in machines of comparable power in the autonomous electromechanical complex. Unlike other autonomous complexes with asynchronous machines only a complex is generalized compensated anautonomous asynchronous generator plus an asynchronous motor appears capable of working in the modes of starting and acceleration of asynchronous motor of comperative with the generator of power. Such starting comes true at the tripleincrease of total capacity of excitation by comparison to hersize for the normal mode.
