Abstract |
High quality power supplying of high voltage distribution lines electric railway system is the important function high voltage distribution system is complicated witch is compose with distribution line, circuit break, protection facilities and so on Among this components, role of substation is most important for elevation of reliability in electric power system. Therefore, the enhanced reliability considering the preventive inspection, repair work, replacement is necessary. This paper proposes protection method in railway high voltage distribution lines. we model distribution system using PSCAD/EMTDC(Power System Computer Aided Design/Electro Magnetic Transients DC Analysis Program) and extract various fault data In conclusion this methods can protection of ground fault. |
