Considered is the control of the reactive power factor of the power supply system of an industrial enterprise, which includes: electrical receivers with asynchronous load; workshop transformer substations with and without regulated capacitor units, as well as the main step-down substation with synchronous motors powered from it. It is proposed to consider electrical receivers with capacitor units and a transformer substation as an object of reactive power factor control, on the basis of which the corresponding automatic control system (ACS) is built. An ACS with an algorithm formed as a function of active and reactive power of electrical receivers is considered. The ACS was developed by the reactive power factor of the power supply system of the entire enterprise with shop combined loads. A method is given for calculating the capacity of capacitor units of shop substations. The use of this control system will allow meeting the regulatory requirements for ensuring the limiting values of the reactive power coefficients and thereby reducing losses during the transportation of electricity and increasing the throughput of the electrical network.
