FIELD: electrical engineering; routine checkup and/or control of synchronous machines in power stations or installations incorporating mentioned electrical machine.
SUBSTANCE: proposed method and device for routine checkup of revolving synchronous electrical machine incorporating wound rotor and wound stator are used to measure stator winding current and voltage, rotor winding current, and temperature at minimum two points in electrical machine using electrical machine simulator and definite currents and voltages. These method and device make is possible to compensate for temporary high reactive power demand without detriment to available active power.
EFFECT: enhanced effectiveness of machine operation and its annual mean power output when using various cooling agents without introducing any modifications in electrical machine.
