In this paper, a hierarchical control of energy management strategy is proposed based on tram hybrid hybrid system. In this strategy, the top strategy achieves the energy distribution between the various systems under different operating conditions by dividing the running status of trams. And the bottom strategy achieves the energy distribution between multiple sets of each energy system. In the bottom...
In order to develop a fault diagnosis strategy in tramway environment, multiclass relevance vector machine (mRVM) based fault diagnosis strategy for proton exchange membrane fuel cell (PEMFC) of hybrid tramway is proposed. The method can quickly identify three kinds of fault states, such as the low hydrogen pressure, the low pressure of deionized water humidification pump and the bus communication...
