FIELD: electric power engineering.
SUBSTANCE: automatic voltage reduction limitation (AVRL) system in industrial power supply areas 6–220 kV with distributed generation sources, comprises device(s) AVRL, which includes a unit for series disconnection of groups of connections, a unit for series connection of connections, a unit for determining modes of electric network, an analysis unit, a unit for setting settings of AVRL device. Additionally, there is a unit for storage of simulation results and selection of a version of the anti-accident control, a unit of start-up elements AVRL, a unit for monitoring the previous mode, unit for issuing (blocking) control actions and a block of preventive control actions, and analysis unit is configured to monitor process safety systems of industrial production of power district.
EFFECT: taking into account features of industrial power districts with sources of distributed generation at automatic limitation of voltage reduction.
