FIELD: electric power industry.
SUBSTANCE: invention relates to electric power engineering and can be used in educational and research activities in educational institutions. Automated educational-laboratory complex of microprocessor relay protection contains a three-phase power supply unit, a single-phase power supply unit, a unit of measuring current and voltage transformers, a connector unit, a model of a power transmission line, an active load unit, units of current transformers, units of voltage transformers, a personal computer. Additional units of current transformers and additional units of voltage transformers, unit of three-pole switch with electric drive, unit of microprocessor relay protection are introduced. Three-pole switch unit with an electric drive is connected to a single-phase power supply unit, to which a personal computer is connected, as well as three-pole switch unit with electric drive is connected to three-phase power supply unit and microprocessor relay protection unit, which is connected through units of current transformers and units of voltage transformers with a model of power transmission line, connected to a personal computer through a unit of a connector and a unit of measuring current and voltage transformers, as well as to a unit of active load.
EFFECT: invention makes it possible to increase the efficiency of educational and research activities, due to simulation of relay protection and automation systems based on microprocessor units by introducing additional units of current transformers, additional units of voltage transformers, unit of three-pole switch with electric drive and unit of microprocessor relay protection.
