Design of DC Tramway Traction Power Network in Hebron

Abstract

Urban traction systems such as subways and trams transport millions of people every day. Hebron city suffers from the traffic issues, in order to solve the problem, a tramway network will be established in Ein Sara with 3.2 Km track covered with 7 passenger station spaced each 550 m. A brief introduction about electrical railway has been introduced and railway dynamics have been illustrated. DC traction substation was rated and located and the required equipment were selected. A proper earthing system for DC system and equipment was illustrated and current return circuit was designed. Over-head contact lines system and suspension system were designed. A protection scheme for DC traction system was designed. Also the system was simulated to study the system performance.
