aIn the right diagram it is extended to 4 km (Rline = 200 mΩ), which is approx. the maximum distance after which a new traction power substation is placed in the line. 在正确的图它延伸到4公里 (Rline = 200 mΩ),大约是。 最大距离,在之后一个新的牵引力量分站在线安置。 [translate] ...
The raw data are collected from Danyang traction substation in Jiangsu, China. The specifications of ESS are set as 20 MW in power and 3200 kW h in capacity. The triggered value of peak shaving and valley filling is set as 22.4 MW. The simulation results of power diagram before and after...
Unlike the traditional traction power supply system which enables the electrified railway traction substation to be connected to power grid in a way of pha... Q Li - 《Journal of Modern Transportation》 被引量: 25发表: 2015年 Research on Fault Diagnosis and Protect Model for DC Traction Power...
Hence the traction load is smoothly decreasing at one substation while increasing at the neighboured substation as the train runs along the line. Thus load steps caused by cut off power of trains when passing neutral sections will not occur. The impacts of flicker and voltage dips on the 3-...
In contrast to the Imax function, the fluctuation of the substation voltage and the voltage drop under load is taken into account with this function. • Frequency monitoring This frequency monitoring function is used to monitor the harmonic component at the contact line. • Switching ...
DC-link voltage, contact-line voltage, and traction chain current are presented. Initially, the system is operating at a stable state close to the substation; then, the power supply impedance is increased in three steps. The first step change of 0.5·𝑍𝑠0.5·Zs occurs at 𝑡=5t=5 s...
Table 1. Specifications of the traction substation, autotransformer, and the trains in the simulation. Due to real-time operation and for better convergence of the optimization algorithm, Equations (15)–(19) were used for generating the initial population in the decision space. As mentioned, tw...
Figure 6: Diagram showing a 3rd rail DC power supply system and how current rail gaps are provided where the substations feed the line. Normally, each track is fed in each direction towards the next substation. This allows for some over supply and provides for continuity if one substation ...
