Introduction of static frequency converters on SEPTA's 25 Hz commuter rail system
A Southeastern Pennsylvania Transportation Authority (SEPTA) project to replace its 1928-vintage rotary converters and one of its converter stations with static frequency converters (SFCs) is described. An examination is made of the development of this project, including the rationale for maintaining a 25 Hz traction power system. The specific emphasis is on the power factor control and harmonic distortion on the utility company's 60 Hz system. The negotiations with the utility company to connect the first SFC to the existing 13.2 kV service and to provide a 230 kV service for the addition of two more SFCs are also discussed.<>
