Soške Elektrarne Nova Gorica d.o.o. (SENG), an affiliated company of the Slovenian Energy Group HSE, has decided to invest in the first PSPP in the country. SENG has decided to install a 195 MVA reversible variable-speed unit providing several advantages when compared to the traditional solutions with fixed speed. The AC Excitation was delivered as a containerized solution, including the converter, control and protection cubicle and the water cooling unit. The ABB AC Excitation system is based on state of the art, three-level, and voltage source converter (VSC) topology. The control system of the AC Excitation is based on ABB's AC 800PEC platform, specially designed for high-speed control of power semiconductors. The control cabinet contains the AC 800PEC controller hardware and all the necessary I/O devices from/to generator/motor control system, AC Excitation converter, excitation transformer, cooling system and voltage/current transformers.
