MULTIFUNCTIONAL FREE-RUNNING ASYNCHRONOUS GENERATOR Russian patent published in 2014 - IPC H02K17/14 H02K3/28 

FIELD: electricity.

SUBSTANCE: invention is related to the sphere of electric equipment and may be used for production of asynchronous generators of stand-alone power plants. Technical result is attained by the reason that in a multifunctional free-running asynchronous generator with capacitor excitation and a stator winding made of six coil group having outputs the first output of the winding is taken from the united end of the fourth and beginning of the first coil groups, the second output of the winding is taken from the united end of the first and beginning of the second coil groups, the third output is taken from united end of the sixth and beginning of the third coil groups, the fourth output is taken from the united end of third and beginning of the fourth coil groups, the fifth output is taken from the united end of the second and beginning of the fifth coil groups, the sixth output is taken from the united end of the fifth and beginning of the sixth coil groups, in parallel to the above stator windings there are six in-series delta-connected excitation capacitors, which can connect these capacitors and outputs of the second, fourth and sixth capacitors as per the wye-wye connection scheme and the load is connected to these outputs in compliance with the voltage value and phase number matching the required load.

EFFECT: expanding scope of application for multifunctional free-running asynchronous generators that allows changing the generator power and connecting load to different voltage.
