DEVICE FOR MODELLING THREE-PHASE MULTIPLE-WINDING TRANSFORMER Russian patent published in 2013 - IPC G06G7/62 

FIELD: electrical engineering.

SUBSTANCE: proposed is a device intended for modelling a three-phase multiple-winding transformer containing a computing unit; the digital input of the computing unit is connected to the digital input-output of the microprocessors unit, to the digital input-output of the multi-channel analogue-digital conversion unit, to the digital outputs of the digital-controlled longitudinal commutation units and the digital-controlled transversal commutation units; the other digital input-output of the microprocessors unit is connected to the PC/server; connected to the computing unit outputs are the multi-channel analogue-digital conversion unit and 3n voltage/current converters the number whereof is determined depending on the number of windings of the transformer being modelled, n, where n≥2; the outputs of each group of three per phase installed voltage/current converters are connected to the inputs of the computing unit, the inputs of the corresponding digital-controlled longitudinal commutation units and the digital-controlled transversal commutation units; the inputs/outputs of the digital-controlled longitudinal commutation units represent phase inputs/outputs of the device.

EFFECT: enhancement of transformer modelling accuracy and extension of functional capabilities of transformer modelling devices through ensuring automated change of parameters of the transformer being modelled.
