CURRENT TRANSDUCERS CONTROL METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC H02J3/18 

FIELD: electricity.

SUBSTANCE: invention is used in electrical engineering. Phase current values are registered at the junction (2) and are converted to current components of positive-sequence system, voltage values are registered at the junction (2) phases and are converted to voltage components of the negative-sequence system connected to the voltage controller. In order to reduce current in the negative-sequence system in the voltage controller (17) current components are generated for the negative-sequence system and supplied to input (28) of rated voltage values for the voltage controller (9). Current components of the negative-sequence system are at the input (8) of actual voltage values for the voltage controller (9) while values at the voltage controller output serve as switching current for switchgear at the current transducer.

EFFECT: eliminating negative-phase sequence voltage in polyphase electricity transmitting network (1) with polyphase connection (2).
