Abstract
The article deals with studying the power supply system. At present the problem of saving energy is particularly acute. It is solved by means of reducing consumption (introducing modern energy-saving technologies) and reducing energy losses. One of the components of the electrical power loss is the presence of reactive power in the enterprise network. Reactive power is generated by electrical equipment with inductive resistance. The presence of reactive power has a negative impact on the electrical network of an industrial enterprise, namely, the networks capacity is reduced, and the load on power transformers increases. The authors propose an integrated approach to introducing compensation devices to reduce losses, provide a calculation of the compensation sets power depending on the active load of the enterprise and depending on the power factor.
