Uninterruptible power supply devices are the main sources of operational DC power supply to control devices and control devices. In addition, the charge-discharge rectifier devices in thermal power plants and substations are autonomous operational current sources of power plants and substations. This source is the main constant and alternating current source for relay protection devices, telecommunication devices, control and monitoring devices in power stations and substations. As switching devices, the most commonly used ones today are thyristor, controlled by the thyristor control electrode. It is possible to control the charging and discharging processes of the batteries. In this case, random charging or discharging of the battery will reduce its service life. Therefore, this article examines its management system. Today’s high-power uninterruptible power supply rectifier devices show that stations and substations are not ready for emergency situations due to their unstable operation and inability to control the state of the battery. Therefore, the improvement of this device remains the major issue.
