FIELD: oil and gas industry.
SUBSTANCE: invention relates to the sphere of production and preparation of gas condensate to a distant transport, in particular to automatic control of pump units providing supply of condensate to the main condensate line. The output of the parallel operating pump units is controlled by changing the frequency of the supply three-phase voltage, which is supplied to the electric motor of each component from its frequency converter. The frequency converter is assigned to frequency converter by individual proportional-integral-differentiating controller included in the structure of the automatic control system of technological processes of the plant for complex preparation of gas. The load is distributed as a function of the magnitude of current in power circuit of components of electric motors by changing the thereof rotation rate by frequency-controlled drive.
EFFECT: The load is distributed as a function of the magnitude of current in power circuit of components of electric motors by changing the thereof rotation rate by frequency-controlled drive.
