The solution of these problems, in some situations, is directly related to voltage regulation. Improving the reliability of the electric power system, equipment of power plants and substations, as well as reducing losses in electric networks, require optimal voltage regulation. Due to the constantly changing circuit-and-mode situation in electric power systems, the high workload of the dispatching and operational personnel, especially during the repair campaign, the need to take into account a number of factors that affect the operating mode of the electric power system, voltage regulation by dispatching and operational personnel is manually, necessary automation of the process of voltage regulation in electric networks.</p>
<p style="text-align: justify;">The article discusses the current principles of voltage regulation in the electric network of the Unified Energy System of Russia, outlines the main practical tasks related to voltage regulation. To solve these problems, it is proposed to create a special regime automation, namely, a centralized system for automatic voltage regulation. The structure and operation algorithm of a centralized system for automatic voltage regulation are described.</p>
<p style="text-align: justify;">The implementation of a centralized system of automatic voltage regulation in the Unified Energy System of Russia will reduce energy losses, as well as ensure acceptable voltage levels according to the requirements of the quality of electricity and working conditions of insulation of electrical equipment and prevent (eliminate) unacceptable current overloads of power lines and equipment in cases where the implementation of this tasks using existing tools are difficult. The implementation of such automation also allows to relieve dispatching and operational personnel.</p>voltage regulation automationcontrol computer complexcalculation model for assessing the stateoptimization of voltage and reactive power modevoltage graphавтоматизация регулирования напряженияуправляющий вычислительный комплексрасчетная модель оценивания состоянияоптимизация режима по напряжению и реактивной мощностиграфик напряжения[STO 59012820.27.010.001-2013.
