CONTROL SYSTEM OF ELECTRIC ENERGY STORAGES FOR EXPANSION OF RANGE OF PERMISSIBLE MODES OF GENERATING INSTALLATIONS OF SOURCES OF DISTRIBUTED GENERATION AT VOLTAGE FAILURES

摘要

FIELD: electricity.;SUBSTANCE: invention relates to electric power industry and can be used in industrial power districts for expansion of range of permissible modes of generating installations of sources of distributed generation at voltage dips occurring in networks of external and internal power supply 6–220 kV, to prevent excessive tripping of generating installations by relay protection devices. Task set is achieved by a system for controlling electric energy storages for widening the range of permissible modes of generating installations of distributed generation sources at voltage dips comprising synchronous generators, current transformers, voltage transformer, accumulator, control system, electronic switch, rectifier, controlled inverter connected to control system, higher harmonic filter.;EFFECT: technical result consists in improvement of reliability of power supply by taking into account load characteristics of industrial consumers.;1 cl, 10 dwg
