This paper presents a balanced 3/1 supply scheme for electrified railway. By employing an active filter, the current of the three phase power delivery system is balanced while the load is in single phase, which makes it possible for the traction system to behave like a three phase balanced pure resistance load to the power delivery system, with unity power factor and no harmonics. Simulation results are presented to verify the scheme′s topology and control regularity.

A fault current limiter (FCL) with series compensation is proposed. Triggered vacuum switch (TVS) is the key control apparatus in FCL. Its structure, principle, characteristics, and the way to choose parameters of the capacitor and reactor in FCL are introduced. Because of the replacement of many power electronic components series parallel connection with single TVS, investment of the FCL and its power loss during operation is reduced. Combining series compensation function with fault current limiting function in one device improves device use rate. As the FCL limits fault current, it can also mitigate the overvoltage of capacitor group. Theory analysis shows the device can improve power delivery systems stability. With simulation method comparing model with FCL and model without FCL proved the FCL can limiting fault current and it is useful for total power network mechanical stability and thermal stability design.
