Control unit of a hybrid power device to power a traction unit, hybrid power system and associated method

摘要

Control block of a hybrid power supply device for supplying a traction engine, hybrid power supply system and associated method Method of controlling a hybrid power supply device (6, 7, 13) of a train and comprising a primary source of energy (6) and a battery (7) and transported by a mobile platform (10) integral with the train (1), comprising: according to a power demand of said train on the cable of power (3), determine the power required by the train at the current instant; determining the power deliverable at the current instant by the primary energy source and by the battery, and, if said deliverable power is lower than said required power, determining, according to a template indicating a maximum power callable by the train as a function of the cable voltage, the cable voltage value corresponding to a maximum callable power equal to the maximum of the deliverable power; controlling the application of said determined voltage value, or of a voltage value lower than said determined voltage value, on said cable by said hybrid power supply device (6, 7, 13) for the supply of the train.
