Abstract

Load in the utility network is predominantly non-linear and generating the highest harmonic components of current in the electrical power network, increases in the overall structure of electricity consumption. The results of experimental measurements and calculations for a number of household consumers as well as information from literature sources noted in the article indicate that the operation of modern appliances in electrical power networks generates sufficiently large currents of higher harmonic components of 3, 5, 7 and 9 orders of magnitude. The main share of emission of the current harmonic components in the city electrical power system networks is made by recreational and household appliances (computers, laptops, printers, TVs, etc.). Continuous growth of the specified capacity of nonlinear asymmetric and sharply variable loads in the electric power networks is not followed by timely implementation of solutions aimed to improve the quality of electrical energy, so, in recent years, the task of improving the quality of electricity associated with reducing the impact of higher harmonic components on the operation of electrical equipment is becoming more and more urgent and important. The listed measures and technical means of influence reduction of the higher harmonic components are considered in the article in details.
