Abstract
The optimal conditions for provision of a required power factor at the point of electric energy transmission in the reactive power compensation mode in a low power supply system of industrial enterprises are considered. Resonant phenomena in a 6/10-kV network with cosine capacitors are investigated. A conformity analysis of the voltage unsinusoidality to the norms set by GOST (State Standard) 32144-2013 was carried out. The values of the maximum permissible rated power of the higher harmonics source depending on the short circuit power, taking into account the permissible overloading of capacitors by a higher harmonics current, as well as provision of correspondence to the requirements concerning the standard for the harmonics composition of the voltage at the point of transmission of electrical energy, are determined.
