MAQOLA ANNOTATSIYASI

Due to the increase in population and the process of industrialization, energy needs have increased. The issues of ensuring the quality of electricity (CE) systematically arise in the electric power systems (EES) of different countries of the world. This is due to an increase in the share of electric receivers (ES) with specific loads in power supply systems, which lead to distortion of the shape of the voltage curve and to an increase in electricity losses in the networks. The deterioration of the indicators characterizing the quality of electricity in relation to the normative values according to leads to additional heating of the current-carrying parts of generators of power plants. This issue is of particular relevance in the EES with a significant share of the load capacity in relation to the installed capacity of generators. Modern power supply systems are connected to many non-linear loads. There are known ways to improve QE, including using the latest CLOUD COMPUTING monitoring information technologies. The influence of lowquality electricity in the power grids between the supplier and the consumer is considered. The ways of practical solution of the problem of electricity quality are given. The analysis of existing devices for measuring the quality of electricity and their main characteristics is carried out.
