Abstract

The article identified the place of electricity in the world market economy, noted the growing problem of lack of energy resources. The principles of reliable and uninterrupted power supply to consumers during a certain period of time are determined, the role of external factors on the quality of electricity supply is indicated. The paper notes that the main consumers of electricity are industrial facilities, whose technological processes are characterized by the presence of nonlinear loads, which leads to the emergence of transients that significantly affect the parameters of power supply systems, causing fluctuations in system parameters. In the presence of nonlinear consumers, their operation is able to produce reactive power in the network, which causes the circulation of power between the energy source and its consumers and leads to numerous negative phenomena - increased losses in conductive elements, the need for high power equipment, increasing cable and wire the emergence of harmonic fluctuations, increasing economic losses during operation. The paper reviews a wide range of literature sources devoted to the introduction of means and methods of reactive power compensation, determines the relevance of such studies. It has been proven that the variety of application conditions and the wide range of reactive power compensation devices require the use of modern computer software to study the operation of power systems. A model of the energy system was drawn up, which has the maximum approximation to the real scheme and contains loads of active-inductive nature. Based on the simulation results, graphical dependences were obtained, illustrating the nature of the change in maximum voltage and reactive energy production without and when applying reactive power compensation measures.
