“…In [38] there is the concept of the system for monitoring power supply reliability and power quality (SMR&Q) based on sensors for monitoring electrical parameters at both sides of a switching device -devices for monitoring the number and duration of power outages and voltage deviations (DMPO&VD). These sensors are installed at the consumers' inputs, at the outgoing electrical transmission lines (ETL) and at the low voltage (LV) buses of a transformer substation (TS).…”

“…The paper [14] focuses on introducing the coordinated voltage control technique for solving a voltage quality problem. Also, there is a large number of already developed means for increasing PSR and PQ, for example, systems for regulating electrical power quality parameters (for example, adaptive automatic voltage regulation [15]), transformer substation automation systems (Automatic Transfer Switches (ATS), automatic circuit reclosers (ACR) [16], under-frequency load shedding (UFLS), buses' load balancing [17]), systems of automatic regulation (compensation) of reactive power [18], [19]. At the same time, the implementation of these means as well as using methods for increasing PSR and PQ, including ones mentioned above, requires monitoring the electrical network parameters in order to accurately and quickly respond to any changes in a power supply system [20].…”

This article describes the features of voltage regulation in electrical networks of 35, 110, 220 kV. The structural diagram of the 35/10/0.4 kV network is presented. The paper also describes the adaptive automatic voltage regulation system which allows regulating the voltage taking into account the actual voltage values at the consumers’ inputs. The structural diagram of the adaptive automatic voltage regulation system in the 0.4 kV electrical network using a boost transformer as an additional means of voltage regulation is given. The system is based on voltage sensors installed in different parts of an eletcrical network sending information on voltage values to to the processing unit which generates a signal for voltage regulating supplied to the executive device and the working body whuch, in turn, change the on-load tap-changer position of a transformer. The paper justifies the need for the enhancement of the adaptive automatic voltage regulation system for different voltage classes wich allows controlling a voltage change at different power supply system levels and regulating voltage level in accordance with this change. For this problem the multi-level adaptive automatic voltage regulation systemis proposed. The system allows regulating the voltage not only in the 0.4 kV network but also in networks of higher voltage classes. The proposed system can be integrated into the structure of intelligent electrical networks.

“…The responsibility of the power supply organization to consumers for the reliability of providing them with electric power and its quality, in accordance with technical regulations and other mandatory requirements, is defined in the "Federal Law on Electric Power Industry". According to [1][2][3][4][5], consumers need to be supplied with electric power of appropriate quality. Power quality (PQ) is one of the factors affecting the work of electrical receivers, switching devices, etc.…”

The problem of improving power quality (PQ) in the integrated power grid of Russia is an urgent task. The article analyzes the number of power consumers' calls to Kromskiye District Power Networks "Orelenergo", a branch of the PJSC "IDGC of the Center" for the issue that power quality indices go beyond the standards established in the regulations. The most common complaints of power consumers are low voltage, high voltage, voltage fluctuations. This is primarily due to physical and obsolete depreciation of the main power grid equipment of the power supply organization, disinterest of consumers and the power supply organization in maintaining power quality at the level of regulations, as well as the lack of power supply or-ganization's software products that allow real-time voltage loss calculations and offer measures to improve the power quality. The presented algorithm, based on calculations of voltage losses, suggests measures to improve the power quality. The application of the proposed algorithm of the program will allow to increase PQ by means of timely determination of voltage losses.
