“…Modern railway line voltage stabilization is made using a static VAR compensator (SVC), located near the neutral zone [19,20] , or using mobile reactive power compensation strategies [3,21,22]. The railway power conditioner system (RPC) is employed in conjunction with V/V transformers and offers very good performance regarding 3-phase power balancing and power factor correction [10,23,24].…”

The high dynamic power requirements present in modern railway transportation systems raise research challenges for an optimal operation of railway electrification. This paper presents a Monte Carlo analysis on the application of a power transfer device installed in the neutral zone and exchanging active power between two sections. The main analyzed parameters are the active power balance in the two neighbor traction power substations and the system power losses. A simulation framework is presented to comprise the desired analysis and a universe of randomly distributed scenarios are tested to evaluate the effectiveness of the power transfer device system. The results show that the density of trains and the relative branch length of a traction power substation should be considered in the evaluation phase of the best place to install a power transfer device, towards the reduction of the operational power losses, while maintaining the two substations balanced in terms of active power.

“…In this section we demonstrate, using time-domain simulations, the referred capabilities of the RIPFC system regarding active and reactive power management: balancing the active power supplied by both substations and imposing a near unitary power factor in the substation. Of course, the reactive power capability could be used to stabilize the voltage Eng 2024, 5 at the neutral zone point, but this functionality is usually achieved by an SVC only [23,24]. As already pointed out in the phasor analysis, we will show that compensating the reactive power in the substation has a side effect of also stabilizing the voltage along the catenary.…”

This paper gives an overview of the operating characteristics of the railway interline power flow controller (RIPFC) regarding the capability of transferring active power between two sections of an electrified railway line separated by a neutral zone and proposes its use for compensating the power factor at the substation instead of regulating the voltage level at the neutral zone. The basic analysis is based on simplified steady-state models for the energy supply architecture, while detailed time-domain simulations are used for more realistic tests. The paper mainly focus on active power balancing between two neighbouring substations and the global losses in the system. Other functionalities of the RIPFC system are also analysed, like reactive power compensation at the substations. The paper presents the main operating principles of the system, shows results for some representative scenarios (generic and reduced) and discusses the results. The most relevant conclusions are related to substation active power balancing and peak shaving, power factor compensation in the substation, voltage stability at the neutral zone and system power losses.
