At an electrical power plant that includes multiple bus systems and consumers, a looped network structure with radial feeders is currently implemented. Each bus can be supplied by multiple sources, usually two or three. However, in case of an outage, there is currently no automatic power restoration to the buses and, consequently, to the consumers. As part of the project, a solution for switching automation has been considered and implemented to ensure voltage switching at two levels. The first level involves local switching at five key bus connection points within the plant, while the second level involves cascaded switching when it is necessary to ensure power supply to multiple buses for uninterrupted plant operation during outages. The task of the switching automation system is to automatically sequence the power supply of the plant's internal consumption based on defined primary, secondary, and/or tertiary power sources. This is done using positional signaling, voltage presence, protection system checks, and other conditions. The switching automation system ensures sequential power supply to the plant's own consumption of electrical power. Additionally, it is responsible for enabling the black start sequence of the power plant using a diesel generator. Since the plant's own consumption includes electrical motor drives, equipment for synchronism control and fast switching is required to ensure uninterrupted power supply to the motor drives during voltage switching. All switching automation systems should be interconnected and exchange information. They should be integrated into the existing SCADA system, allowing intuitive control of voltage switching by the operational staff.
