Progress in the design of the DTT electrical distribution system

The Divertor Tokamak Test (DTT) facility is a key project for the exploitation of nuclear fusion as a sustainable source of energy. The accomplishment of this goal necessarily passes through the appropriate design of the Electrical Distribution System (EDS) managing the power, flowing from the national grid to the loads required for the facility operation. This design is not trivial due to the huge amount of power, the high number of loads with different characteristics and the inherent discontinuity of the operation. The objective of this paper is to present a general overview of the development on DTT EDS. Its architecture and design are based on the results obtained by Power Flow and Fault Analyses, implementing simulation models. The main criticalities and open issues are pointed out for future improvements and to provide guidelines useful for other similar facilities.
