SYSTEM CONTROL METHOD FOR CATENARY-LESS TRAM IN DEAD BLOCK

摘要

PURPOSE: A system control method of a tram with less catenary in a transition a catenary section and a less catenary section is provide to steadily drive the system in a reciprocity transition from a catenary section to a less catenary section. In a catenary section, a tram with less catenary is driven by supplying electricity through a feeder. In a less catenary section, a tram with less catenary is driven using electricity of a battery mounted inside the vehicle. CONSTITUTION: A system control method of a tram with less catenary capable of transiting a catenary section and a less catenary section comprises the following steps: a first step which controls a DC/DC converter(150) to a discharge state, and which controls an HSCB(High-Speed Circuit Breaker)(130) to an open state in order to be put into an input terminal of an inverter(120) controlling a motor(110) for driving a vehicle by a power source of a battery(100) when a vehicle is driving in a less catenary section; a second step which controls in order to block an operation of a DC/DC converter, and which conducts the HSCB in order to operate a vehicle by a coasting when the vehicle enters in a transition section from a less catenary section to a catenary(1) section; and a third step which controls to block an operation of the DC/DC converter, and which maintains the HSCB in a conducted state in order to apply a catenary power supplied through a catenary to the inverter when the vehicle completely enters in a catenary section.
