- W4309228410 abstract "Nowadays Platform Screen Doors have become an essential safety infrastructure for high-speed metros, rapid rails, and bullet trains. PSD provides safety barriers, improved climate control, improved security, and reduced noise pollution in stations. The automatic sliding door is the main component of PSD which is driven by BLDC DC motors and controlled by door controllers. The dynamic weight of a single ASD may vary from 80 to 150 KG. ASD doors are generally installed in series along the platform and motors will operate with DC voltages. This result in a system with distributed DC inductive loads. Voltage drop varies in series from door to door. For a platform of 24 doors, 48 BLDC motors will work in series for half-height PSD and will require approximately 4kW of constant DC power and approx. 7kW of starting DC power. Considering all these requirements, an efficient power distribution scheme without single point failure is required. For calculating wire gauge, MCBs, fuses, and other distribution components mathematical modeling of inductive motor loads, and resistive cables are carried out and simulation results are analyzed to achieve efficient distribution architecture. Component selection criteria are discussed. Modeling and simulation carried out in ORCAD spice software. An efficient distribution scheme is proposed with calculated wire gauge regiments, MCB type with tripping curve requirements, single point failure avoidance scheme, and source load requirements are discussed." @default.
