To date, the operation of electric receivers with a nonlinear characteristic is accompanied by the generation of higher harmonic components of currents and voltages in the network. As a result of these processes, there is a decrease in the quality of electricity, an increase in electrical energy losses, as well as equipment failure. As a result, there is an increase in the need for funds to compensate for the harmonic components of currents and harmonic voltages. The paper presents a study of the effect of electric receivers on electricity in the network (as an example, a simulation model is made for a high-voltage mine network in the Matlab software package with the Simulink extension package and the SimPowerSystems library).
