Problems of the current state of power quality and proposals for their solution

Abstract

The power quality in Russian electrical networks does not meet the requirements of regulatory documents. Big problems occur in all areas of people’s lives for this reason. Economic damage is one of the serious consequences. In the context of digitalization of the economy, the requirements for the power quality are increasing, because digital electrical equipment requires high power quality. The paper presents the history of solving the problem of thepower quality in Russia, including three periods - before the adoption of the Federal Law “On Electric Power Industry”, after its adoption and after the adoption of the resolution of the Russian Government on the creation of a digital economy. Examples of the consequences of low power quality. To achieve a high level of power quality, it is proposed to create a power quality management system that meets the requirements of the emerging intelligent electrical power systems and digital economy.
