THE TECHNICAL FEASIBILITY OF RAILROAD ELECTRIFICATION WITH HIGH VOLTAGE (10-50 KV) DIRECT CURRENT

High-voltage (10-50 kV), direct-current power distribution may prove to be an economically and technically attractive option for railroad electrification of the future. There may be potential economic advantages in both wayside installation and operation, and in the propulsion equipment aboard the rolling stock. However, before an economic comparison with AC systems can be completed, the technical feasibility of DC systems must be determined, which is the purpose of this paper. This paper is directed toward the wayside equipment only. The problem of HVDC rolling stock is not considered. This analysis shows no technical obstacle to the use of HVDC power distribution systems for application to the wayside portion of railroad electrification. Circuit breakers, which can be applied to these systems, are in various stages of development, and with reasonably directed research can meet the duty requirements. Likewise, rectifiers which can satisfy both current and voltage requirements are within the state of the art. An alternate to using the DC breaker, namely, sectionalizing on the AC side of the system, is a viable option. This option may sacrifice some operational flexibility as well as performance.
