| Summary: | One of the important requirements for electricity supply is ensuring the quality of electricity, which is understood as the degree of compliance of quality indicators with accepted standards. Deviation of voltage and other quality indicators from established norms significantly affects the operation of electrified equipment and electrical networks, which leads to electromagnetic and technological components of economic damage. Also, voltage asymmetry is one of the urgent problems of 0.4 kV three-phase electrical networks. The asymmetry of the voltage is manifested in the inequality between the models of the phase voltage vectors and the shift angles between them.
IEEE Std 1100-2005. IEEE Recommended Practice for Powering and Grounding Electronic Equipment [1] (hereinafter IEEE) and DSTU EN 50160:2014 "Characteristics of power supply voltage in electrical networks of general purpose" (hereinafter DSTU) [2] establish indicators and norms of power quality in electrical networks of power supply systems general purpose alternating three-phase and single-phase current with a frequency of 50 Hz at the points to which electric networks owned by different consumers of electric energy or receivers of electric energy (points of general connection) are connected.
The power quality standards established by the standard are electromagnetic compatibility levels for conductive electromagnetic disturbances in general purpose power supply systems. In compliance with established standards of electricity quality, electromagnetic compatibility of electrical networks of energy supply organizations and electrical networks of electricity consumers is ensured.
