For this reason, regenerative inverters are increasingly installed in the substations of urban rail transit systems.

Up to now, the regenerative inverters have been used in more than 20 metro lines in China. The energy saving of   Likewise if the negative currents of the inverting substations exceed the maximum inverter DC current, the substation voltage sources are replaced by current sources of the current values of the maximum inverter DC current.

In order to reduce the voltage fluctuation of the DC network and improve the energy efficiency, the conventional diode rectifier is replaced by the controlled rectifiers in [8], [9], [17].

Railway rapid transit systems are key stones for the sustainability of mass transit in developed countries. The overwhelming majority of these railway systems are direct-current (DC) electrified and several energy-saving techniques have been proposed in the literature for these ://   The use of controlled rectifiers in the traction substations (TSs) was considered much later.

Thus, the first thyristor controlled rectifier (TCR) was put into service by Dallas Area Rapid Transit (DART) in the early nineties to take advantage of the DC voltage control, fault current limiting and leading to.
