  • the normally open contacts (a1, a2) of the closing relay are closed, and the normally open contacts (d1, d2) of the emergency relay 642 open after a delay of 3s after the coil loses power, so the coil of the medium voltage bus contactor 62 is delayed.

  • the first normally open auxiliary contact (k1, k2) of the medium voltage bus contactor 62 feeds back the closed state of the medium voltage bus contactor 62 to the processor 63; the second normally open auxiliary contact of the medium voltage bus contactor 62 (k3, k4) is closed to form a self-locking circuit, so that the coil of the medium-voltage bus contactor 62 is maintained in an electrified state.
  • the delayed opening of the emergency relay 642 ensures that the main inverter (mk1, mk2; mk3, mk4; mk5, mk6) of the medium-voltage bus contactor 62 opens its output contactor before closing to avoid differences Phase AC voltages are superimposed to cause overcurrent.

In addition to maintaining a good stable operation capability in the normal mode, it can also fully operate in the fault mode. The complementary and coordinating role of the systems is brought into play, thereby reducing the impact of failure, increasing the redundancy of auxiliary power and the availability of grid-connected power supply modes.

Abstract

La présente invention se rapporte à un système de commande d'alimentation électrique raccordé au réseau pour un véhicule ferroviaire urbain, et à un véhicule ferroviaire urbain. Le système de commande comprend un premier relais (11) et un contacteur de barre omnibus de tension moyenne (12). Le premier relais (11) est raccordé au contacteur de barre omnibus de tension moyenne (12) et à un processeur (13), et est utilisé pour recevoir une première instruction de commande envoyée par le processeur (13), et commande la mise en marche ou l'arrêt du contacteur de barre omnibus de tension moyenne (12) selon la première instruction de commande. Dans le système de commande d'alimentation électrique raccordé au réseau, la mise en marche ou l'arrêt du contacteur de barre omnibus de tension moyenne (12) est commandé non pas par un niveau haut ou bas émis par un système de réseau, mais par le premier relais (11) en fonction de la première instruction de commande reçue. Par conséquent, même si une défaillance se produit dans un module d'entrée/sortie du système de réseau, un système d'alimentation électrique de train se maintient dans un mode d'alimentation électrique raccordé au réseau avant que le premier relais (11) reçoive une instruction de commande, améliorant ainsi significativement le taux d'utilisation du mode d'alimentation électrique raccordé au réseau.
