DEVICE FOR TOLERANCE CONTROL OF TRANSIENT FREQUENCY DEVIATION Russian patent published in 2023 - IPC G01R31/00 H02P9/00 

FIELD: electrical engineering.

SUBSTANCE: means for functional diagnostics of electrical units with internal combustion engines, part of systems for diagnosing the technical condition of mobile power stations for assessing transient frequency deviation during load surge. A device for tolerance control of transient frequency deviation is proposed, consisting of a generator 1, clamps for connecting 2, a starting element 3, a diode 4, a limiter-shaper 5, an inverter 6, a short pulse shaper 7, the first 8 and second 9 delay elements, the first 10, second 11 and third 12 logical elements I, first 13, second 14 and third 15 memory registers, first 16 and second 17 subtractors, first 18, second 19 and third 20 numerical comparators, first 21 and second 22 master registers, memory block 23, stable frequency pulse generator 24, pulse divider 25, pulse counter 26, RS trigger 27, indicator 28, START bus 29, three-phase active power sensor 30 with digital output, first 31 and second 32 logic elements OR, electronic switch 33, second shaper 34 of short pulses and the second RS-trigger 35.

EFFECT: increasing the efficiency of the assessment.
