At present, the traction supply system of electrified railways has adopted phase rotation power supply technique, the power supply mode results in electrical phase-splitting of the contact line, which reduces the capacity and safety of electric locomotive. By ensuring the output voltage strict accordance of each phase power supply device, smooth cophase power supply system can be constructed, completely cancel the electric phase-splitting, but multiple cophase power supply device through the parallel power supply will bring line circulation problem. Therefore, this paper analyzes the parallel circulation problem of the electric railway in cophase power supply system, using the control theory of non reciprocal connections, a general circulation suppression strategy is proposed for the parallel operation of multiple cophae power supply devices. The simulation results show that the parallel control strategy can effectively restrain the circulating current in traction network, which can greatly improve the capacity of the line.

With the development of science and technology, the demand for high quality power supply electrical equipment increasing application of analog circuit Control Research and Application Development of power for many years already, but it still has many shortcomings. FPGA as a highly integrated, economical, high speed, low power consumption, it is easy to develop and maintain a significant advantage (upgrades) and the like. And faster, more integrated, more versatile, and other advantages, stand out from the MCU and DSP integrated circuits, etc., become the research and application in the field of power electronics control hot spots. Briefly introduces the basic theory of digital systems, we analyze the structure model of digital systems. There is an overview of the design method of digital control system, the completion of the selected device selection and related development environment and tools. This paper proposes all-digital power control scheme of special surface treatment, and the completion of the controller hardware and software design and implementation.

“…Mochinaga proposed the RPC [9]; different control strategies and structures have also been proposed [10][11][12]. On the other hand, Li proposed the co-phase TPSS configuration [13], which was applied to engineering in 2011 [14]; various other structures have also been proposed [15][16][17]. Compared with the co-phase TPSS, the apparent drawback of RPC is that it cannot eliminate the neutral zones.…”

The severe power quality problems aroused by the single-phase 25-kV traction power supply system (TPSS), especially for the voltage unbalance (VU) and high-frequency harmonic resonance, have attracted increasing attention nowadays. In this paper, a novel hybrid power quality compensation system, including a power flow controller (PFC) and thyristor-controlled L and C-type filter (TCL-CTF), is proposed. The PFC can be used for VU compensation, and the TCL-CTF can be designed to filter out harmonics as well as compensate reactive power. Furthermore, an optimized compensation strategy is proposed, and the power quality of the TPSS can meet the requirements of the technology standard. Compared with the conventional scheme, the compensation capacity of the PFC can be reduced by 12%, as well as the cost. Finally, the effectiveness of the proposed system is verified by the simulation and experimental results.
