Electric Power System Architecture for the Proton Accelerator Conventional Facilities

The Proton Engineering Frontier Project (PEFP), approved and launched by the Korean government in July 2002, consist of a 100 MeV proton linear accelerator development and programs for its utilization and application. According to PEFP, expected to complete in March 2012, proton accelerator research center will be founded on the project host site where Korean government will select. In this paper, electric power system architecture for the proton accelerator conventional facilities in PEFP is described. To supply electric power to the proton accelerator conventional facilities in PEFP, we adopted 154kV substation facilities with 2 transformers. For the emergency power system, we adopted emergency diesel generator, battery and UPS. To show the usefulness of the proposed electric power system, we compare them to that of SNS now constructing in USA and ESS in Europe
