CONTROL METHOD OF FUNCTIONING OF ROTATING ELECTRIC MACHINE AND CONTROL SYSTEM FOR IMPLEMENTATION OF ABOVE SAID METHOD Russian patent published in 2015 - IPC H02K11/00 G01R31/34 

FIELD: electricity.

SUBSTANCE: invention relates to a control method of functioning of a rotating electric machine, namely an asynchronous double-current machine with a power range of 20-500 MVA. The invention proposes a control method of functioning of a rotating electric machine that includes the following: a rotor rotating about the axis and concentrically enveloped with a stator; the rotor and the stator include a multilayered rotor element and a multilayered stator element respectively, which are assembled of sheets laid in layers and pressed in an axial direction with formation of laminated material and compressed by means of electrically insulated tightening bolts passing through the multilayered rotor element and the multilayered stator element in an axial direction and insulated relative to the multilayered elements; with that, to each of the tightening bolts there supplied is the specified potential relative to the corresponding multilayered element by means of a voltage source, and current passage through the voltage source and/or through the corresponding tightening bolt is measured and evaluated.

EFFECT: reliable control of insulation of tightening bolts during continuous operation of a rotating electric machine.
