6 System composition
6.1 Overview
The ground system for vehicle braking regenerative energy utilization of urban
rail transit is divided into:
- feedback-type ground system for vehicle braking regenerative energy
utilization;
- storage-type ground system for vehicle braking regenerative energy
utilization;
- hybrid-type ground system for vehicle braking regenerative energy
utilization.
6.2 Feedback-type ground system for vehicle braking regenerative energy
utilization
The feedback-type ground system for vehicle braking regenerative energy
utilization is composed of energy-fed transformer, AC (low voltage) circuit
breaker, double quadrant converter, DC isolating switch, DC reactor,
measurement and control system and so on. The typical topological structure
of the main circuit is shown in Figure 1.
The energy-fed transformer completes the electrical isolation between the
double-quadrant converter and the AC grid and the functions of step-up and
step-down. AC (low-voltage) circuit breaker realizes protection and isolation
between the double-quadrant converter and the energy-fed transformer. The
dual-quadrant converter realizes the conversion function of electric energy from
AC to DC or from DC to AC. The DC isolating switch realizes the isolation of
the double-quadrant converter and the DC negative bus. The DC reactor
completes the filtering and current limiting functions with the DC bus. The
measurement and control system complete the measurement, protection and
contro...
