1. Способ стабилизации и регулирования параметров электроэнергии в трехфазных электросетях, по которому меняют величину и фазу добавочного напряжения на участке цепи или величину сопротивления этого участка путем перевода вспомогательных трансформаторов в различные режимы работы с помощью переключения тиристорных ключей этих режимов в определенные моменты времени, отличающийся тем, что переключение тиристорных ключей этих режимов выполняют за несколько промежуточных этапов, в каждом из которых исключают разрыв цепи тока нагрузки и перенапряжения на тиристорных ключах, а моменты перевода устройства в различные промежуточные этапы выбирают в зависимости от фазового угла нагрузки, совпадающими с временными зонами естественной коммутации выключаемых на этих этапах тиристорных ключей.1. A method of stabilizing and regulating parameters of electricity in three-phase power networks, which changes the magnitude and phase of the additional voltage in the circuit section or the resistance value of this section by transferring auxiliary transformers to different operating modes by switching thyristor switches of these modes at certain points in time, characterized in that the switching of the thyristor switches of these modes is performed in several intermediate stages, in each of which the breaking of the load current circuit and overvoltage on thyristor switches, and the moments of transferring the device to various intermediate stages are selected depending on the phase angle of the load, coinciding with the time zones of natural switching switched off at these stages of thyristor switches. 2.
