Reactive power control

Bulletin of NTU "KhPI". Series: Problems of Electrical Machines and Apparatus Perfection. The Theory and Practice, 2021
В статье исследуются способы управления режимами реактивной мощности. Показано, что обеспечение экономичности передачи и распределения электроэнергии неотделимо от постановки и решения задач, связанных со снижением потерь электроэнергии в сетях. Причем одним из наиболее эффективных способов снижения потерь электроэнергии, а также повышения ее качества ...
