Fig. 1 is the structure and position view of EMS in tractive power supply system provided in an embodiment of the present invention, referring to Fig. 1, EMS is by central controller and energy transfer converter (the Energy Transfer for being connected in parallel on all differential gap two sides Converter, ETC) composition.ETC is used and RPC (Remote Procedure Call Protocol, remote procedure call association View) identical circuit topology is two-way AC-DC-AC converter.EMS connects all power supply sections using 2n -1 ETC, So that whole railway power system " perforation ", provides hardware foundation to expand the flow range of regenerating braking energy.Center control Device processed optimizes allocation algorithm using regenerative brake power according to the traction power or regenerative brake power information of each power supply section, The transimission power of each converter is calculated, and it is given as it to distribute to each converter.The controller completion pair of each converter The closed-loop control of transimission power.By the coordinated control of central controller and ETC, the common orderly stream for completing regenerating braking energy Dynamic and optimization distribution, improves effective rate of utilization of the regenerating braking energy in tractive power supply system.

The present invention realizes that the principle of full line regenerating braking energy regulation is based on following three points:

1, during optimizing distribution to full line regenerative brake power using EMS, regenerating braking energy is in route It is unavoidable with the loss in device for power switching.However no matter regenerating braking energy is to flow directly into public electric wire net, also It is to flow to traction load after being regulated and controled by EMS, can all generates line loss.Simultaneously as the AC resistance of contact net unit length Value is smaller, and accounting for for line loss is smaller, such as the line loss of regenerating braking energy accounts for about in high speed rail system 0.2%.Therefore the present invention ignores line loss, only considers transducer effciency.If ETC uses cascaded H-bridges structure, it is also necessary at it It outputs and inputs side and increases step-down transformer, therefore its efficiency is 1 γ 2 of η=γ γ, wherein γ is the change of bi-directional electric power electronics The efficiency of parallel operation, γ 1 and γ 2 are respectively the efficiency of left and right sides step-down transformer.If ETC uses MMC structure, can be direct Supply arm is connected, is not necessarily to transformer, then its efficiency eta=γ.No matter any structure is used, the present invention is by the efficiency of each ETC Uniformly it is denoted as η.

2, since regenerating braking energy will cause by multiple ETC transmission simultaneously, efficiency is lower, energy waste.Therefore, may be used It at most can be simultaneously by ρ ETC transmission to set the regenerative brake power in each power supply section.Meanwhile in order to reduce change as far as possible Parallel operation loss maximally utilizes regenerating braking energy as principle using preferential neighbouring power supply section, optimizes the corresponding power supply section of distribution Interior regenerative brake power.

3, when a certain power supply section memory needs to shift in regenerative brake power, and the adjacent power supply section of its two sides is When with electricity condition, no matter to which side transmission regenerating braking energy, it can achieve the purpose that improve regenerating braking energy utilization rate, But since safe operation of the TS input side three-phase current unbalance to power grid will cause greatly to threaten, and it is this unbalanced The difference power of main cause two power supply sections in same TS.Therefore, consider for regenerating braking energy to be transferred to first Power supply section in same TS, remainder consider further that the power supply section for being transferred to the other side adjacent thereto.This is beneficial to Reduce the difference power of two power supply sections in same TS, and alleviates the imbalance of three-phase current.
