Abstract :
The research work presented in this paper proposes a compensation scheme to overcome voltage fluctuation on traction transmission line due to uncertainty in operation of locomotive loads under a section of traction transmission line(50 km) fed by local substation. Sudden loading of multiple locomotive loads on traction line yields to dip in voltage and voltage across locomotive motor may drop beyond its rated voltage and inefficient operation of motor takes place. Due to excessive load on a section of traction line of finite length may trips the circuit breakers without any fault on line. Application of Static VAR Compensator (SVC) in shunt with transmission line can effectively overcome the dip in voltage. Extensive simulations have been done to study the effect of multiple loads on section of traction transmission line.
