Abstract The electrified railway has power quality problems such as three phases seriously unbalanced, large harmonics, and reactive power. In addition, the neutral section exists at each supply section, which restricts development of high-speed heavy-haul railway. This paper proposes a novel co-phase traction system (TPSS) based on YNvd balanced transformer, can not only solve above but also s...

It is very difficult to built reliability design model of structural parts working in a complex and uncertain environment because of their dynamic time-dependent characteristic, an intelligent method of reliability analysis based on integration algorithm is presented in this paper, RBFNN and finite element analysis combined with Monte Carlo numerical simulation is integrated to improve simulati...

Zhangjiakou regional network belongs to the Jibei power grid in Northern China and locates at the midway of the power transmission corridor from Inner-Mongolia to the rest of Jibei power grid. Zhangjiakou regional network consists of several area networks connected to the main network through 500kV stations. In recent years, renewable energy in rural areas has developed rapidly and electrified ...

With the increasing requirements of railway sector for electrified railways and development society, traction power supply system needs to become more flexible, economic reliable. The traditional has many problems due its own topology, such as negative sequence current, load fluctuation, low utilization rate regenerative braking energy, inability use distributed generation along railway. In ord...

The penetration of electric vehicles is becoming more and widespread recently buses trains are fetching the attention researchers developers. In this review, we examine charging systems applied to fast as well strategies, mainly buses. We also briefly delve into power topologies for a electrified railway system where discuss their different supply motor drive systems. Problems charge challenges...
