FIELD: power engineering.
SUBSTANCE: invention relates to electric power engineering and can be used in power districts for expansion of range of permissible modes of generating installations of distributed generation sources at short-term frequency deviations arising in networks of external and internal power supply 6–220 kV in order to prevent excessive shutdowns of generating installations by relay protection devices. Task set is achieved by the electric energy accumulator control system for expansion of the range of permissible modes of generating installations of distributed generation sources at short-term frequency deviations, including synchronous generators, current transformers, voltage transformer, a frequency measurement unit, a unit for measuring derivative frequency, a storage unit, a control system, an electronic switch, a rectifier, a controlled inverter connected to a control system, a high-order filter.
EFFECT: technical result consists in creation of control system of electric energy accumulator to prevent outages of generating units at short-term frequency deviations providing reliable power supply and taking into account industrial load peculiarities.
