| Abstract |
Recently, power quality problems in A.C High-Speed Railway system have been raised, because heavy train and its higher speed are required in addition to new control system by using the Electronic devices. The installation/operation of the Series Capacitor(SC) has been only a device for voltage drop in power system up to now. However, the sufficient effectiveness of compensating on voltage drop has not been proved yet because of technical limitationof SC, and harmonic resonance is attracting a attention as one of new issues. Several problems are expected such as locational problems of a traction substation, and overloading caused by a new construction of electric railway and the increment in transport. Therefore, extension of power feeding during the fault in the traction substation should be also considered. So this paper represents the application of TSC-SVC on the electric railway power feeding system as a device of voltage compensation, and the simulations are executed through PSCAD/EMTDC. |
