METHOD OF INCREASING ENERGY EFFICIENCY OF PRESSURE GAUGE UNITS WITH CENTRIFUGAL ELECTRIC PUMPS CONTROLLED BY CONTROLLED FREQUENCY CONVERTERS UNDER LAW OF PID REGULATION Russian patent published in 2017 - IPC F04D15/00 F04D13/14

Abstract RU 2623585 C1

FIELD: engines and pumps.

SUBSTANCE: method of increasing energy efficiency of pressure gauge units with centrifugal electric pumps controlled by frequency converters according to PID regulation includes determination and monitoring of the operating pumps number n, measurement of active load current of each running pump motor I_ai, determining the deviation of the active load currents of each running motor from their rms value, calculated according to the formula , stepwise input of the correction value of the control signal frequency in the control unit for each running motor equal to the product of the least significant digit of the control frequency by the scaling coefficient I_ai=o_a.

EFFECT: improved energy efficiency due to improvement of its general efficiency during the pressure head regulation process in the pressure mains of a customer.
