| 摘要 |
<p>The present invention relates to a power supply network including at least one connection point (PCO) for connection to an upstream electrical network (REA) supplying operating power (Pf) to at least one input of a first power supply network (RE1) for supplying power to an electrically-propelled transportation system (ST) such as a trolley, tramway, subway, train or other forms of transportation, wherein said first electrical network (RE1) has peak-power fluctuations in accordance with the variable energy needs depending on the traffic associated with the transportation system, characterized in that: the first electrical network (RE1) comprises at least one power output (SP) capable of distributing energy, in particular energy recovered from the transportation system (ST) and the upstream electrical network (REA), to at least one second electrical network (RE2) for supplying power to power consumption points (Sc); at least one supervising unit (UC) monitors the energy distribution of said power output (SP) when at least the peak power required by the first transportation system (ST) is lower than the operating power (Pf) available upstream.</p> |
