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 fillin
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 ...

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]...
FIG. 3 represents a variant of the supply system according to the invention using an extra low voltage power supply substation placed at each stopping station and this all along the length of the line; FIG. 4 is a circuit diagram of the power supply means on board the vehicle, ...
Keywords: traction substation transformer; traction load shock; total harmonic distortion; transient impulse voltage; temperature rise; partial discharge 1. Introduction Traction substation transformers are one of the key components of the traction power supply and distribution system of a high-speed ...
The main innovative value of the work is to improve a simulation model of a trolleybus grid through a data-driven approach by using measurements of voltage and current output from a traction substation. The measurements are essential for understanding the behavior of vehicle weight variation through...
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 ...
