    Abstract : The introduction of performance based tariff regulations along with higher media and political pressure have increased the need for well-performed risk and asset management applied to electric power distribution systems (DS), which is an infrastructure considered as a natural monopoly. Compared to other technical systems, DS have special characteristics which are important to consider. READ MORE

  3. 3. Optimal Railroad Power Supply System Operation and Design Detailed system studies, and aggregated investment models

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Lars Abrahamsson; Lennart Söder; Arnd Stephan; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Railway power supply systems (RPSSs) differ mainly from public power systems from that the loads are moving. These moving loads are motoring trains. Trains can also be regenerating when braking and are then power sources. These loads consume comparatively much power, causing substantial voltage drops, not rarely so big that the loads are reduced.
