Analysis of NPP power distribution in Bangka Island for electricity system of Sumatera

Energy diffusion target on the regulation No.5, 2006, says that 2 % of total national energy need is come from nuclear energy. National Nuclear Energy Agency (BATAN) as the promoter of the development Nuclear Power Plant(NPP), has made a long term road map, whereas in the year of 2024, Nuclear Power Plant from Bangka Island will be injected to the Sumatera interconnection system. For the system and transmission planning preparation, the simulation has been made with Electrical Transient Analyzer Program (ETAP) Software. The are three assumption in this research, 10,2 % annual load growth until 2024, enhancement of NPP with 2 x 1000 MW capacity at Bangka island, and improvement of the system and transmission line to deliver the power from NPP to Sumatera interconnection system. The research result gives that the optimum power distribution by north Sumatra sub system through IBT Seirotan or Paya Geli. Total losses whole system of this distribution is 157 MW or 1,646%, and improvement total IBT condition voltage as many as 43,4 % . (author)
