The needed high level of reliability and availability of power supply is achieved through an appropriate power supply concept. A double power supply system with modular thyristor rectifiers that operate in redundant parallel connection according to the principle n + 1, is foreseen. Each system has its own battery and main distribution board. Sub distributions are deployed in relay houses and each will be powered double-sidedly, independently from both DC sources.
The final factory system testing was carried out in the presence of purchaser’s representatives on end of February 2018, and the equipment delivery and works on the facility are planned for the April.
