METHOD TO CONTROL STATIC STABILISED DC VOLTAGE SOURCES OPERATING IN PARALLEL INTO COMMON LOAD Russian patent published in 2010 - IPC H02J3/46 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in organising electric power generation systems or uninterrupted power supply systems with sources connected in parallel into common load. Proposed method comprises generating voltage setting signal and measuring voltage at common load and output current of every source, generating negative voltage feedback signal and extra voltage signal by integrating negative voltage feedback signal. It includes also generating voltage control signal at common load by summing negative voltage feedback signal and extra voltage signal, generating load current portion setting signal for every source at common load in proportion to common load voltage control signal, proportionality coefficient being equal to source rated current-to-load rated current ratio, generating negative current feedback signal and extra current signal by integrating negative current feedback signal, and generating control signal for every source by summing three components, i.e. extra current signal, negative current feedback signal and that proportional to current of the given source.

EFFECT: expanded performances in standard and post-fault operating conditions.
