FIELD: converter engineering.
SUBSTANCE: proposed system designed for automation of control processes for group of parallel-running water-pump induction-motor drives has adders, integrator, odd number of relay components, diagnosing unit built around series-connected frequency divider, proportional-differential section, and demodulator. INHIBIT function buffer, thyristor voltage regulators incorporating provision for phase control, 2AND function units, and driving induction motors connected to water pumps.
EFFECT: enhanced operating reliability of system due to automatic throwing of serviceable regulation channel in operation.
