“…In addition, transient process II and transient process IV, the pantograph arcing is taken into account. We have built an extended habedank's equation‐based electromagnetic transient program (EMTP) model of pantograph arcing considering pantograph‐catenary interactions and HST speeds . This model is a combination of Mayr's equation‐based arc model and Cassie's equation‐based model, which can reflect the nonlinear characteristics of pantograph arc.…”

“…Here, the actual CRH2‐300‐Type locomotive speed of China Beijing‐Tianjin HSR line is applied. Considering the excessive HST before the main circuit breaker disconnect under the idle operation, when the train speed will be reduced passing the commutation phase connection section, so taking HST speed v = 280 km/h (ie, v = 280 km/h in the model).…”

“…Alternating current (AC) high‐speed railway (HSR) has been developing quickly over the past decades, with a combined length totaling 20 000 km and top traveling speed 380 km/h up to the September 10, 2016, due to the Zhengzhou‐Xuzhou HSR in China . However, traction power supply system (TPSS) is a special single‐phase power network, and locomotive is a fast‐moving and heavy‐current load . Compared with the other locomotives, the high‐speed train (HST) has the advantages of high efficiency, energy savings, and low emissions .…”

“…And the complex electromagnetic transient process will appear. Currently, the researchers regarding HST's passing spilt‐phase insulator mainly focus on the pantograph arcing and the overvoltage . As for the pantograph arcing, on the basis of the arcing test apparatus, Midya et al and Lan et al analyzed the influences of spilt‐phase overvoltage and harmonic, and the process of HST's passing spilt‐phase insulator under the generating arc was simulated in Cesario et al As for the spilt‐phase overvoltage, the impact of locomotive load on the spilt‐phase overvoltage was studied in Hsi and Chen and Jiang et al By using the resonance principle, Zhou et al analyzed the mechanism of the split‐phase overvoltage.…”

Summary In single‐phase alternating current (AC) traction power supply system, to balance 3‐phase load of power system, each phase of electricity is used in rotation. Based on the 7‐section articulated split‐phase insulator of China Beijing‐Tianjin high‐speed railway line, different electromagnetic transient processes are deeply analyzed considering pantograph arc and viaduct's electrical coupling in this paper. First, based on the lumped parameter model, the process of high‐speed train passing the articulated split‐phase region, concluding the upper viaduct part and the lower viaduct part, is deeply studied. Second, through state‐space technique, 4 independent electromagnetic transient processes in articulated split‐phase region of high‐speed railway are derived and analyzed thoroughly considering the impact of pantograph arc and viaduct. Finally, the integral transient process is accurately simulated and analyzed by ATP‐EMTP software under several circumstances, such as different topologies, initial phase and phase difference of feeders, and specific suppression overvoltage measures. The independent and integral comparison results illustrate that the coupled viaduct can lead to the more complex topologies and electromagnetic transient processes. Also, the coupled viaduct can play a significant topology discharge and pantograph overvoltage suppression role for the high‐speed train passing articulated split‐phase region.
