FIELD: electricity.
SUBSTANCE: device for uniform distribution of reactive power between voltage supplies connected to parallel operation is equipped with voltage controls of those supplies with equal number of input clamps of each control, transformers of parallel operation and as many groups of coils of the first and the second differentiating measurement current converters as each control has input clamps; each of the above coils of any group is connected to current lead of load current of one of voltage sources; in addition, there also introduced are equalising connections, one for each group of coils of the first and the second differentiating induction measurement current converters; such number of block contacts of switches of voltage supplies and switches connected between beginnings and ends of primary windings of transformers of parallel operation is introduced that the device can have one transformer of parallel operation, one block contact and one switch to each input voltage control terminal of each voltage supply. Transformers of parallel operation, which refer to one voltage supply, form block of transformers of parallel operation, one block per each voltage supply.
EFFECT: improving electric energy quality, eliminating pulses of the voltage generated with voltage supply when it is not connected to common buses at simultaneous provision of possibility of parallel operation of any voltage supply with the other one not covered with the action of the device for uniform distribution of reactive power.
