SYSTEM AND METHOD OF MONITORING SYSTEM OF PARALLEL CONVERTERS Russian patent published in 2021 - IPC H02J3/36 H02J3/12 

FIELD: electrical equipment.

SUBSTANCE: invention relates to electrical engineering and discloses a method and system for monitoring a system of parallel converters. System of parallel converters includes common AC voltage controller and separate current controllers of each converter, wherein AC voltage controller generates reference values of active current, reactive current and phase of system voltage, these values as converter control signals by means of communication are sent to current controllers of each converter operating in island mode, at that, active and reactive current of the converter changes after the corresponding reference value of current, realizing the task of joint monitoring of voltage amplitude and frequency of AC supply lines by a system of parallel controllers.

EFFECT: technical result consists in improvement of efficiency and reliability of synchronization of several converters.
