  • Patent number: 9809118
    Abstract: A system and a method for parallel power supply control for auxiliary converters of a motor train unit in the presence of interconnecting lines. The system comprises multiple three-phase inverter modules. The multiple three-phase inverter modules are in parallel connection with each other. Any two-phase circuit of a three-phase inverter module is separately in parallel connection with a corresponding two-phase circuit of a three-phase inverter module adjacent to the three-phase inverter module by using a connecting line module. The connecting line module is connected to a control system. The three-phase inverter modules are also connected to the control system. The three-phase lines of the three-phase inverter modules are all provided with switches.

  • Publication number: 20170154393
    Abstract: A computer-implemented method of relating transport incident reports for transport incidents resulting from the same transport accident. A transport incident report including transport incident data for a transport incident is received, where the transport incident data includes at least geographical and temporal data for the transport incident. Transport accident data associated with a set of stored transport incident reports is retrieved, which also includes at least geographical and temporal data. The transport incident data and transport accident data is used to determine that the received transport incident report relates to the same transport accident as the set of stored transport incident reports. The received transport incident report is then added to the set of stored transport incident reports.
