Provide an impact analysis on the energy supply assets if frequency increase is implemented on the Metro network. Design the new assets needed to run at this frequency in the N scenario and N-1 scenarios of all the substations.
Use the RET metro model to perform the study. The following questions can be solved: - How many new AC feeding points in the medium voltage network are needed to deliver all the necessary power to the network? - How many new substations are needed in the network and where they need to be placed? - How many new traction groups of existing substations are needed? - How many new feeding cables are needed in order to deliver all the power to the system? - How many km of aliuminium steel are needed in the 3rd rail feeding system to maintain the voltage above 600V? - Which strategies can be applied to maintain the rail-earth voltage below 120V?
