“…For CMII and CMIII, it can be seen from Equation ( 21) that the value of ε U1p and ε U1q are not unique, and the value of K N1 and K N2 are also not unique according to Equation (22), when the value of ε U1 is given. And the value of K C1 and K C2 are also not unique according to Equation (24).…”

“…For CMI, as the negative sequence current generated by I Lp1 and I Lq1 is compensated independently each time, when the value of ε U1 is given, the value of ε U1p or ε U1q is also determined uniquely, and the value of K N1 and K N2 is also determined uniquely according to Equation (22). In the same way, the value of K C1 and K C2 can be obtained according to Equation (24).…”

“…As the PF remains unchanged, according to (24), it can be obtained that K C = K C1 = K C2 = 0. According to Equation (22), the value of K N1 in case 2, 3 and 4 are 0.039, 0.57 and 1 respectively. The simulation is carried out according to the strategy shown in Figure 4, and the three-phase current of A, B and C at PCC after simulation is shown in Figure 11.…”

“…Different from the parallel bilateral power supply adopted by Russia, a tree‐shaped bilateral power supply is proposed, which can effectively avoid the generation of extra power flow [20, 21]. In order to avoid the problems of train passing through the neutral section, automatic over‐phase technologies are applied in Japan and other countries, but the negative sequence problem remains unsolved [22]. In China, researchers have done a lot of beneficial researches on co‐phase power supply technology, especially the combined co‐phase power supply technology, which can cancel the neutral section at the exit of traction substation [5, 23].…”

With the large‐scale increasing demand for passenger transportation, the alternating current (AC) 25 kV traction power supply system (TPSS) of electrified railway is introduced into the construction of urban rail transit in China instead of the direct current (DC) TPSS. In order to suppress the negative sequence current and cancel the neutral section at the exit of traction substation of the AC TPSS, a novel AC integrated power supply system (IPSS) of the urban rail transit based on single‐phase static var generator (SVG) is proposed, which the capacity of SVGs can be further reduced. The topology of the novel AC IPSS is introduced. By defining the constraint factors of negative sequence current and reactive power compensated, the comprehensive compensation model of negative sequence current and reactive power of the novel system is established based on the corresponding standards, which the full compensation and satisfactory compensation can be achieved. The method of determining the compensation scheme and the control strategy are proposed. Taking the actual data as an example, the effectiveness of the compensation scheme is proved. In addition, the correctness of the control strategy proposed is proved by simulation and experiment.

AcknowledgementsThe energy storage system for d.c. traction power supply was realized by introducing technologies of Hitachi Corporation and the system of "zero-emission station" was of Mitsubishi Electric Corporation, respectively. We deeply acknowledge their sincere cooperation. AbstractAfter the 3.11 earthquake in Tohoku district in Japan, energy saving and renewable energy utilization become one of the important problems in Japan. East Japan Railway Company, as a public transportation company, tries to contribute to solve these problems by realizing eco-friendly railway transportation system. In this paper, three realized and under construction projects are summarized which enhance efficiency of traction power supply system. First project is installation of lithium ion battery at Haijima Substation on February 20th, 2013 to make use of regenerative power in d.c. traction power supply. Second project is the power conversion application to be installed at Ushiku sectioning post for a.c. traction power supply and will start operation in the end of 2013 fiscal year. The last project but not least one is "zero-emission station" realized at Hiraizumi Station on June 28th, 2013. The total electric power of the station is supplied from solar power even in the evening using lithium ion batteries. The detail of the operation data of "zero emission station" is shown in this paper.
